Advanced Circuit and Electrical Testing (ACE)

This class is about using wiring diagrams as part of a larger strategy to increase testing accuracy and decrease testing time (and even the number of tests performed). We’re combining wiring information with codes, symptoms, system interactions, Scan Tool PIDs & controls, and other observations. Without having tested a single circuit you’ll be able to: 

  • Classify the fault (open, short to ground, short to power, short to circuit, resistance faults, etc.)
  • Trace series & parallel current paths through diagrams for every operating condition
  • Cross off whole sections of the wiring diagram that can’t be the cause
  • Select fast and simple tests appropriate for the conditions and for the classification

A/C Service Essentials (ACS)

Brief Review of Fundamentals

  • Types of compressors
  • Heat exchangers
  • Pressure reduction devices
  • Refrigerant storage devices

  • Normal gauge readings for various types of compressors

Advanced Scan Tool Diagnostics (AST)

This seminar was built using a completely different approach – to show the best PIDs, controls and other Scan Tool functions to use for each diagnosis. Instead of simply explaining Scan Tool functions, we’ve organized the seminar and manual by OBD II Monitors and trouble codes. This gives you a very specific diagnostic strategy based on how the PCM determines that a trouble code needs to be set and what PIDs and controls are supported for each system variation. There are dozens of examples of this strategy in action, diagnosing the most common powertrain codes including:

  • P0171 & other Fuel Trim codes
  • EVAP leak and other functional failure codes
  • Misfire code isolation techniques
  • EGR functional and flow codes
  • O2 and Air/Fuel sensor codes
    • There are also examples showing similar strategies at work solving various body & chassis trouble codes, as well as Scan Tool no-communication faults. This isn’t a button-pushing seminar – come to learn great new techniques for zeroing right in on a root cause.

Chrysler Engine Performance (CEP)

Chrysler diagnostics have always been challenging because of parts incompatibility, failed new parts, no-code faults, and trouble codes that really mean something else. So DENSO has assembled the best tests and tricks to get past all of these diagnostic distractions. This seminar covers new systems through 2012, but we’ve also taken a fresh look at common diagnostic problems on systems back to 1996. As usual, we help you get the most diagnostic information with the least effort. With this information you can ‘think’ your way through diagnostics to beat the flowchart.

  • New Atkinson (variable compression) engines
  • Definitively identifying failed PCMs
  • Crazy Fuel Trim & O2 sensor issues
  • Making sense out of complex position signal faults
  • Discerning between engine timing & trigger faults
  • Best tests for LDP, NVLD & ESIM EVAP systems

GM Duramax Diesel Engine Performance (DDP)

More and more GM Duramax 6.6 liter Engines are coming into repair shops with an Engine Performance issue or Check Engine (C/E) Light "ON". Come to this class and get the training and information you need to quickly and correctly diagnose and repair the five generations of this engine:

  • Unique Duramax Systems & Components
  • Intake Air Heater
  • New Exhaust Particulate Filter & Service
  • Glow Plug Systems
  • High and Low Pressure Fuel Supply Systems
  • Fuel Injector Diagnosis
  • Common Rail Fuel Injection System
  • Variable Geometry Turbocharger
  • Engine Management Strategies
  • Fuel Injection Control Module (FICM)

Evaporative Emissions Systems (EES)

OEM flowcharts routinely make EVAP system diagnostics too complicated. Despite the wide variety of systems out there, our research has revealed that a layered approach is much faster than the linear OEM approach, leading to a profitable diagnosis without the wasted (and unbillable) diagnostic time or multiple trips for your customer. This is the 2nd subject in our Import Series, but also comes with a thick Domestic section. First, we show you universal techniques applicable to every system. If no leaks are found, the procedures become more system-specific, but not yet manufacturer-specific. All systems fall into one of four categories listed below, and by following our universal procedures, you can still avoid the technical nonsense that typically lengthens diagnostic times! Most faults are found using these first two layers. We have also included manufacturer and systemspecific tips and tricks for those cases where you’ll need to go that deep.  

System coverage includes:

  • Traditional & Split Purge/Seal Systems
  • Leak Detection Pumps (KOER & Key-OFF)
  • Natural Vacuum (EONV, NVLD, ESIM)
  • DMTL (comparative current flow)


Emissions Theory & Diagnosis (ETD)

Most technicians must now diagnose emissions and evap system failures. This course will help you evaluate and repair emissions control systems and drivability problems prior to smog/emissions testing. It can also help you maintain professional credentials such as ASE L1 test certification or the BAR 90 certificate.

If you are new to emissions diagnostics, it will provide you a basis to understand OBD-I and II diagnostics, diagnose emissions related drivability DTCs, and diagnose and Repair EVAP system failures:

  • Identification of common emissions failures and how to test the various systems
  • Review evaporative emissions system function and testing procedures
  • Discuss factors and sensors which might cause emissions failures
  • Explain catalytic converter operation and diagnosis
  • Explain verification tests and PCM reset procedures
  • Describe the computerized systems diagnostic chart flow logic
  • Describe HC, CO, CO2, O2, and NOx emissions failure causes and diagnosis
  • Discuss how a 5-gas analyzer shows component failures

Ford Engine Performance (FEP15)

This all-new Ford Engine Performance training manual and seminar cover the evolving failures of both new and legacy engine management sys-tems. We provide in-the-trenches explanations of systems and failures, including case studies that show the latest tricks for finding root causes fast. This isn’t just a summary of OEM information and training material, but was built by analyzing actual diagnostic struggles and documenting the shortest diagnostic paths.

  • Gasoline Direct Injection (GDI) valve deposits and cleaning restrictions on EcoBoost applications
  • Engine mechanical faults, including the ‘shell game’ of telling the difference between VCT, timing chain, oil pressure, and valve train failures
  • Mechanical pin-type VCT systems as well as traditional oil-controlled VCT systems
  • Tricky symptoms actually caused by Rear Fuel Trim
  • Practical Throttle Actuator Control (TAC) diagnostics
  • The new Universal (Wide Band) HO2S
  • Misfiring: Root cause or just a symptom?


Ford Hybrid Diagnostics (FHD1)

Ford hybrids have been extremely reliable, but they are much more integrated than Toyota hybrids. When they do fail, this integration means that the more invasive Toyota testing methods don’t always apply, and the parts you’ll replace are much more expensive. So if you’re going to diagnose these, it’s very important to be right the first time.

We’ve built this seminar to address the hybrid diagnostic and repair challenges you’re most likely to face, so we’re confident that it contains tests and information you can use now and into the future. This hybrid seminar was built from the actual failures occurring in a variety of Ford hybrid models, so it applies directly to the diagnostic, repair, and normal service challenges you’ll be seeing in your shop. You will learn to confidently diagnose the main hybrid drive components: batteries, inverters and transaxles. However, we’ve also included the following systems and issues you’re likely to be faced with:

  • Identifying module responsibility by model (PCM, TCM, TBCM, BECM, BPSM & BEC)
  • Disabling, interlock circuits, inertia switches, and other power-up/power-down information
  • Traction battery air & HVAC cooling systems
  • Transaxle cooling and controls (MECS)
  • Various combinations of electro-hydraulic braking systems
  • Electric power steering & HVAC compressors
  • Hybrid drive diagnostics, including high voltage isolation faults, battery performance, transaxle performance, battery cooling, and transaxle cooling
      • We show multiple tool & test solutions, including a number of tips you can quickly apply to rule out many faults, saving hours of diagnostics time. Why learn the hard way? Come to this seminar to gain an edge when diagnosing & repairing Ford hybrids.

GM Engine Performance (GEP)

The push for better performance and lower emissions has resulted in some complex new technologies on General Motors General Motors Trucks and Vans with Diesel Engines are coming into repair shops with Engine Performance or Check Engine Light problems every day. In the past, these vehicles may have been hard to repair, or the information to repair them may have been difficult to find. Come to this class and get the latest repair information and help you need to diagnose these diesel engines. Our trainers are presenting a brand new program on the General Motors 6.6 liter Duramax engine. Did you know there are 5 different generations of the Duramax engine? And there are major differences in systems and components between each generation. Let us teach you how to use this information to quickly and accurately diagnose any Duramax engine! Information to be covered in class:

  • Unique Duramax Systems & Components
  • New Exhaust Particulate Filter & Service
  • Intake Air Heater
  • Variable Geometry Turbocharger
  • Glow Plug Systems
  • High & Low Pressure Fuel Supply Systems
  • Common Rail Fuel Injection System
  • Fuel Injector Diagnosis
  • Engine Management Strategies
  • Fuel Injection Control Module (FICM)
  • Honda/Acura Engine Performance (HEP)

    Throughout the 1990s the Honda/Acura product line has grown, and the vehicles and systems are much more complicated. The manual includes hundreds of live Scan Tool, Lab Scope, and Graphing Multimeter captures from known good and faulty systems, as well as, voltage and current measurements.

    This information is not in the factory manual nor in your repair information system! With information not available anywhere else, documented using field research, you will learn how the following systems function on applications from the early 1990s through current year models:

    • SCS Diagnostics
    • Drive-By-Wire Systems
    • VTEC and i-VTEC Systems and Var Intake Manifolds
    • Onboard Ign Voltage Monitoring
    • Multi-Speed Fuel Pumps and Air Bypass Systems
    • HO2S and A/F Sensor Diagnostics
    • Electronic Load Detection Charging Systems
    • Hybrid Vehicle Service

    Hybrid Vehicle Safety & Service (HVS)

    Unlike other hybrid vehicle training, this class does not go into hours of technical explanation for systems you will never work on. The premise of this class is that you need to know what systems you can work on, what systems to leave alone, and how to safely and profitably service these vehicles. Every hybrid vehicle still has a PCM, a gas engine, hydraulic brakes, and standard vehicle components.

    This class takes the mystery out of these vehicles and gets them in-and-out of the service bay profitably and quickly:

    • Driving and operating characteristics
    • Safety information
    • Disabling procedures for the high-voltage systems
    • Drive-By-Wire throttle controls
    • Coil-On-Plug ignition system controls
    • Power conversion and inversion
    • Normal engine services (fluids, mechanical repairs)
    • Dual cooling systems
    • Regenerative braking

    Intermittent Electrical & Drivability Diagnostics (IED)

    DENSO seminars contain great strategies for thinking your way through a diagnosis. However, most strategies call for duplicating the symptom or code. This can be extremely frustrating with intermittent problems. Faults are usually present and measurable even if the symptoms or codes are intermittent, so we’ve developed a repeatable strategy for flushing out these elusive faults. Additionally, we have assembled the best tools and tests for isolating faults and validating repairs, including:

    • Customer and technician worksheets
    • Best practices for voltage measuring tools
    • Specific Scan Tool tips and tricks
    • Largely unused DVOM features & functions
    • Homemade tools for:
      • Circuit isolation
      • Fault isolation
      • Load substitution
    • Other inexpensive tools and techniques
    • Tool limitations & traps
    • Case studies to reinforce every concept

    Mechanical & Variable Valve Timing & Lift (MVT)

    Mechanical timing problems have been around as long as the internal combustion engine, but more complex timing and valve train systems have flooded the market in the last decade. Now they’re showing up in your

    shop, and the stakes are high. Position sensor codes are often mechanical or variable timing faults. Variable valve timing (VVT) codes are often mechanical timing faults or lubrication issues. Even Fuel Trim, MAF, MAP, and other codes and symptoms can be caused by a variety of timing and lift faults. When it really is a VVT system fault, it’s hard to tell if the root cause is an oil, solenoid, actuator, or other mechanical fault. What’s

    needed is a repeatable strategy to avoid testing ‘everything’, and instead quickly eliminate possible causes. In this first class of our new ATG Import Series, we’ve fine-tuned this approach to include manufacturer-specific ATG Tips for quick solutions you’d spend hours discovering on your own.

    • Hydraulic, Electronic & Magnetic Clutch VVT systems
    • Variable lift & valve clearance faults
    • Finding stretched/jumped timing without disassembly
    • Differentiating mechanical & VVT failures
    • Stuck actuators vs. stuck solenoid diagnostics
    • Finding internal oiling faults from the outside
    • Leverage Scan Tool PIDs & functions to eliminate the most possible causes with the least effort

    Advanced Scan Tool Beyond the Flowchart (STB)

    This all-new Scan Tool seminar was built using a completely different approach – to show the best PIDs, controls and other Scan Tool functions to use for each diagnosis. We’ve reinvented Scan Tool training because

    button-pushing and menu navigation don’t make you more successful. Rather, success comes when you know your Scan Tool so well that you can set the flowchart aside and ‘make up’ your own diagnostic path.

    Not only is this path more accurate – it’s quite a bit shorter than the flowchart. There are dozens of examples of this strategy in action, diagnosing the most common faults:


    • Fuel Trim codes
    • EVAP leak and other functional failure codes
    • O2 and Air/Fuel sensor codes
    • Misfire code isolation techniques
    • EGR functional and flow codes
    • Body & Chassis codes
    • Scan Tool ‘No-Communication’ faults

    Toyota/Lexus Engine Performance (TEP)

    Now is a good time to prepare yourself to diagnose the engine and emissions control systems on these vehicles! This new training course is packed with critical information that explains how to test and repair OBD II systems (1996-2003), but also includes tips and strategies for those troublesome OBD I components and systems (1990-1995).

    Information Provided:

    • Revised OBD II Drive Cycles
    • Diagnostic Strategies
    • Engine Position Signals (NE, G1, G2, etc).
    • Fuel Injectors & Variable Speed Fuel Pumps
    • IAC, EGR, and Enhanced EVAP Diagnosis
    • Oxygen & Air/Fuel Sensors & Heaters
    • Variable Valve Timing (VVT-i & VVTL-i)
    • Acoustic Control Induction Systems
    • Direct Gas Injection Systems
    • Distributor, DIS, Coil On Plug, and Combination (COP & DIS) Ignition Systems

    Toyota & Ford Hybrid Diagnostics (TFH)

    Early hybrid training was great, but now we have years of data on actual maintenance issues, trouble codes, costly diagnostic mistakes, specific failure patterns and other ‘in the trenches’ information to share. We’re not offering another class about how planetary gear sets work, or theory about brushless AC motors. Because in the shop, those facts don’t fix hybrids. What fixes them in knowing how they systems interact, how they decide to set certain codes, and how to pick the best tools and tests to safely isolate faults.

      LEARNING OBJECTIVES:

    • High voltage battery failures
    • Low voltage faults causing misleading codes & symptoms
    • Battery and transaxle overheating faults
    • Various READY-up issues
    • Escape A/C-cooled traction battery faults
    • Electric power steering and A/C system faults
    • ABS & regenerative braking problems
    • Shifting and Park command faults
    • Prius coolant storage, HC storing cats, and exhaust-heated cooling systems
    • Engine no-start, no-crank, misfire, whining, rumbling, and other diagnostic tips
      • All modern vehicles have systems that communicate with and rely on each other, but this integration is far more complete on a hybrid…and it sets more confusing codes. Both Ford and Toyota modules will see a fault and set a code, but then enter a default operating mode and then set another code for the default condition they just commanded! We help sort through these multiple-code faults codes to help you find the one you should actually be diagnosing. And we’ve included as many testing options as possible so that you have a diagnostic path forward no matter what level of equipment you have.

    Toyota Hybrid Diagnostics (THD1)

    While hybrids have been around for over a decade, the sales numbers really shot up after the initial success of the Gen 1 Prius. This means that there are hundreds of thousands of Gen 2 & 3 Prius, Camry, Highlander and other Toyota & Lexus hybrid models coming out of warranty. So now is the perfect time to prepare for this growing segment of your business.

      Early hybrid training was great, but now we have years of data on actual maintenance issues, trouble codes, costly diagnostic mistakes, specific failure patterns and other ‘in the trenches’ information to share. We’re not offering another class about how planetary gear sets work, or theory about brushless AC motors. Because in the shop, those facts don’t fix hybrids. What fixes them is knowing how the systems interact, how they decide to set certain codes, and how to pick the best tools and tests to safely isolate faults.

        Included are many known good Scan Tool and Lab Scope examples from the most problematic systems, as well as some great fault examples, including:

        • High voltage battery failures
        • Low voltage faults causing misleading codes & symptoms
        • Battery and transaxle overheating faults
        • Various READY-up issues
        • Escape A/C-cooled traction battery faults
        • Electric power steering and A/C system failures
        • ABS & regenerative braking problems
        • Shifting and Park command faults
        • Prius coolant storage, HC storing cats, and exhaust-heated cooling systems
        • Engine no-start, no-crank, misfire, whining, rumbling, and other diagnostic tips
            • All modern vehicles have systems that communicate with and rely on each other, but this integration is far more complete on a hybrid…and it sets more confusing codes. Toyota modules will see a fault and set a code, but then enter a default operating mode and then set another code for the default condition they just commanded! We help sort through these multiple-code faults codes to help you find the one you should actually be diagnosing. And we’ve included as many testing options as possible so that you have a diagnostic path forward no matter what level of equipment you have.

    Transmission In-Car Diagnostics (TIC)

    Whether you’re a transmission specialist or not, you share a common problem – how to efficiently diagnose the root cause of a transmission code or complaint in a reasonable time. This is even more important for

    modern, integrated drivetrains where drivability problems are often transmission-related, and transmission complaints often end up being engine-related. That’s why we’re bringing the strategies we’ve learned from

    emissions and drivability diagnostics into the world of automatic transmissions. Our focused, repeatable strategy allows you to more quickly find the fault while taking apart the fewest components.

    • Quickly differentiate between transmission, engine mechanical, engine management, suspension & other possible causes
    • Use application charts to map out power flow to determine what components are being used under fault conditions
    • More effectively test sensors, switches & solenoids under loaded conditions
    • Leverage Scan Tool PIDs & functions to eliminate the most possible causes

    We’re not trying to teach anyone how to rebuild transmissions – transmission techs already know how, and know that it’s a specialty you need to dedicate considerable time to learning. But all technicians will benefit from diagnosing better and faster. The specialist will use that diagnosis differently than the non-specialist, but whether you end up repairing, rebuilding, subletting, or replacing, ‘fast and accurate’ is better than ‘time-consuming’ and ‘I think it needs.’ We’ve included dozens of real-world examples to prove the point. We’re confident that this seminar is exactly what is needed to make you a lot more successful at diagnosing transmissions, whether you rebuild them every day or haven’t ever had one apart.

    VW/Audi Engine Performance (VEP)

    Throughout the 1990s, the German product line has grown and the vehicles and systems are much more complicated. The training manual includes hundreds of live Scan Tool, Lab Scope, and Graphing Multimeter captures from known good and faulty systems, including voltage and current measurements.

    This information is not in the factory manual or in your repair information system. With information not available anywhere else, documented using field research, you will learn how the following systems function on applications from the early 1990s through current year models:

    • The latest tips and fixes from our talented instructors
    • "Current Track" wiring schematics
    • Repair information on ignition, fuel, and emissions
    • Throttle Adaptation
    • Test and repair Volkswagen and Audi OBD-II systems

    • Diagnósticos con los Indicadores (Gauge)

    Advanced Drivability Diagnostics Strategies (ADD)

    This seminar brings practical and real-world tests to quickly isolate a root cause for drivability and trouble code faults on Domestic, Asian & European gasoline engines. Traditional diagnostics tell us to ‘check the basics’, but that means hours of compression, vacuum, fuel pressure/volume and other time-consuming tests. So we’ve developed top-down tests for engine mechanical and engine management that help you drill down along the most effective diagnostic path. We’ll show you the latest ‘geeky’ tools like transducers and processed Scan Tool functions, but we’ll also include great ways to get results using the Scan Tools and traditional test equipment you already own.

    Most technicians have been using the Scan Tool for years for more than just pulling codes, but very few get the full potential out of this very powerful tool. In this class you will learn what Scan Tools can and cannot do and get tips for diagnosing certain faults without OEM Scan Tools:

    Topics include:
    • Engine breathing tests, including Volumetric Efficiency, VE mapping & crankcase pressure
    • Engine fueling tests, including Fuel Trim by condition, Rear Fuel Trim, and VE relationships
    • Simplified cylinder contribution & misfire detection strategies and root-cause analysis

    Advance Lab Scope (ALS)

    This seminar covers the testing procedures for manufacturer specific systems and components. This new manual & seminar goes deeper into the test equipment instead, so there’s more time to discuss emerging tools & techniques in voltage and current testing. One of the greatest features of the manual and seminar is a thorough explanation of voltage, resistance, and current test strengths and weaknesses for each low current (sensor) and high current (actuator). While we show a variety of tests so you have the flexibility, we focus on the one that makes the most sense for each type of circuit.

    As usual, that’s the test that gives you the most information for the least effort. So you’ll not only pick up some new testing techniques, but you’ll always know the most efficient test to perform first during each diagnosis. Diagnostic time will drop as accuracy increases!

    New to Lab Scopes? The manual is great for the technician that has a dusty Lab Scope not quite sure how to get started. Lab Scope time and voltage settings, trigger, slope and coupling are all covered, as well as specific circuit connection tools, techniques and rules.

    Advanced User? Even the most experienced Lab Scope users will benefit from the cool tricks we’ve gathered from the field, as well as some we’ve developed in-house. We’ll show the logic behind some great time-saving combination tests and back that up with examples from actual repairs.

    Specific topics discusses include:

    • Hand held and PC-based Lab Scopes
    • Little used high side & ground voltage drop waveforms
    • Mechanical analysis using voltage & current waveforms
    • Detailed pressure/vacuum transducer explanations & examples
    • When the Graphing Multimeter function is a better alternative
    • Current probe testing strategies
    • Available minimally-invasive circuit connection tools
    • The best test setup for the specific weaknesses of each component

    Chrysler Ignition & Fuel Systems (CEP1)

    Chrysler diagnostics have always been challenging because of parts incompatibility, failed new parts, no-code faults, and trouble codes that really mean something else. So DENSO has assembled the best tests and tricks to get past all of these diagnostic distractions. This seminar covers new ignition & fuel systems but we’ve also taken a fresh look at common diagnostic information with the least effort.

    Ford Fuel & Ignition Systems (FEP1)

    While Ford design and build quality has improved, the traditional "linear" approach to diagnostic isn’t working any better. In fact, with the increased complexity and system interaction, it’s becoming more important than ever to be able to sort through data quickly to choose the test that gets you the most information with the least effort.

    That takes training! And this training was developed in the field, working on the same problems you see every day in your shop. Our goal, as always, is to offer training that pays you back in faster, more accurate diagnostics, and happier customers.

    This one-night seminar will cover new Ford Ignition and Fuel systems, as well as a fresh look at older systems using information gathered as the vehicles age.

    Ignition System Coverage

    • COP & DIS ignition system construction and numerous test alternatives using Lab Scopes, Scan Tools, etc.
    • Better methods for isolating misfiring

    Ford Air Management & Emissions Systems (FEP2)

    While Ford design and build quality has improved, the traditional "linear" approach to diagnostic isn't working any better. In fact, with the increased complexity and system interaction, it's becoming more important than ever to be able to sort through data quickly to choose the test that gets you the most information with the least effort.

    That takes training! And this training was developed in the field, working on the same problems you see every day in your shop. Our goal, as always, is to offer training that pays you back in faster, more accurate diagnostics, and happier customers.

    This one-night seminar will cover new Air Management and Emissions systems, as well as a fresh look at older systems using information gathered as the vehicles age.

    General Motors Ignition & Fuel Systems (GEP1)

    This class covers all of the newest GM technology, but emphasizes evolving failure patterns on older systems as well. With our tips and intuitive tests, you can quickly differentiate between electronic and mechanical issues plaguing the GM models most likely to come into your shop. Misfire, Fuel Trim, valve seat issues, cam timing faults, and cylinder-kill system failures can all cause similar symptoms and codes. This seminar helps you make a better ‘first pass’ to look for clues that create the shortest diagnostic path. We’ve been refining these ‘beat the flowchart’ methods for years, so you’ll find something you can use right away.

    OTHER TOPICS INCLUDE:

    • New GM “lean” diagnostics (no more flowcharts!)
    • Misfired diagnostics to quickly differentiate between ignition, fuel & base engine faults
    • Emerging base engine failure patterns, including roller lifters & valves
    • New COP cassette ignition with built-in current ramping
    • Tips for finding the root cause of misleading CMP & CKP sensor codes
    • Conventional fuel delivery & injection
    • Gasoline Direct Injection diagnostics
    • Fuel Trim, Rear Fuel Trim & O2 Sensors

    General Motors Air Induction & Emissions Systems (GEP2)

    This GM Air Induction & Emissions Systems seminar is the latest offering in the popular Engine Performance series. While it covers all of the newest information, we’ve also found that older systems are failing in different ways than they were years ago. That’s why we also focused on the existing systems that you’re seeing in the shop today. We’ve designed this seminar so that you get a return on your investment right away as the tests and tips save you time and keep you on the right path. To that end, we’ve included the following information: This new class covers all of the newest GM technology, but emphasizes evolving failure patterns on older systems as well. With our tips and intuitive tests, you can quickly differentiate between electronic and mechanical issues plaguing the GM models most likely to come into your shop. Misfire, Fuel Trim, valve seat issues, cam timing faults, and cylinder-kill system failures can all cause similar symptoms and codes. This seminar helps you make a better ‘first pass’ to look for clues that create the shortest diagnostic path. We’ve been refining these ‘beat the flowchart’ methods for years, so you’ll find something you can use right away.

    Intermittent Electrical Diagnostics (IED1)

    DENSO seminars contain great strategies for thinking your way through a diagnosis. However, most strategies call for duplicating the symptom or code. This can be extremely frustrating with Intermittent problems. Faults are usually present and measurable even if the symptoms or codes are intermittent, so we’ve developed a repeatable strategy for flushing out these elusive faults. Additionally, we have assembled the best tools and tests for isolating faults and validating repairs, including:

    • Customer and technician worksheets
    • Best practices for voltage measuring tools
    • Largely unused DVOM features & functions
    • Specific Scan Tool tips & tricks
    • Homemade tools for
      • Circuit isolation
      • Fault isolation
      • Load substitution
    • Other inexpensive tools and techniques
    • Tool limitations and traps
    • Case studies to reinforce every concept

    Intermittent Drivability Diagnostic Strategies (IED2)

    Other classes teach how every system and component functions, but there hasn’t been a "big picture" class until now. We’ve assembled the best "first" tests that give you the most information with the least effort, so you can drill down to the root cause of a drivability fault faster than ever without getting sidetracked. Simple and easy tests quickly answer the questions: Can it breathe? Is it fueling? and Can we blow it up? These aren’t direct compression, fuel pressure, and ignition tests, but rather inferred test values from commonly available visual and Scan Tool information. This class has everyday value in every shop. You’ll get:

    • Customer and technician worksheets to focus the diagnosis of code and n-code drivability faults
    • Disciplines for testing effectively while not unintentionally correcting the fault before defining it
    • Volumetric Efficiency testing to verify MAF, compression, cam timing, intake, and exhaust systems
    • Fuel Trim testing over a wider range of conditions to let adaptation indicate the nature of the fault

    Hyundai & Kia Engine Performance (KEP)

    Progressively better styling and a consistently low price have finally gained Hyundai & Kia some serious market share. While the return on the time /money invested in receiving specific Hyundai and Kia training has been questionable in the past, we think it’s time to take a deeper look for a few reasons:

    • Hyundai and Kia have some very unique solutions to engine management challenges
    • OE Scan Tools are now very reasonable, and aftermarket tools more capable than ever
    • The Hyundai and Kia OE repair websites are free and accessible to everyone, but the system descriptions are very general, and the flowcharts are more linear and time-consuming than most

    We’ve found that even with free access to information, and increasingly better access to Scan Tool data and functions, it’s hard to earn a diagnostic dollar on these models. At DENSO, we research how each system really "thinks" to create short lists of focused tests. So instead of using a flow chart, you get to "chart your own flow."

    In addition to these issues common to the Hyundai and Kia models you currently see, this class and manual offer a comprehensive look at the best diagnostic practices on the latest systems, including Gasoline direct injection (GDI) and Turbocharging. And just like other DENSO seminars, our goal is to help you leverage the tools and information you have to get the best test results with the least effort. Hyundai and Kia are here to stay, and DENSO is here to ensure that you can profitably service them.

    There’s profit waiting behind these and many more topics unique to Hyundai and Kia:

    • They actually create voltage drop in some ignition circuits to infer current flow
    • Some EVAP systems use heated leak detection pumps – learn how they work and fail
    • Find out how Monitors are disabled by a poorly documented sensor that never sets codes
    • Learn about the strangely named PIDs that you actually know quite well by more common names
    • Hyundai and Kia have long used Air/Fuel sensors, but the signals don’t react like you’d expect
    • Some mechanical procedures are "rigged" for failure, but we’ll help you avoid the traps
    • Poor maintenance causes many variable camshaft issues, so we have some great tips to quickly find these faults

    Hyundai & Kia Fuel & Ignition Systems (KEP1)

    Hyundai and Kia models are gaining market share, so you’ll be seeing more of them in your shop every year. From early OBD II applications through the latest models, their unique engine management systems create some great diagnosis and repair opportunities, but their systems and trouble codes are poorly documented. The most common objection to obtaining Hyundai and Kia training is that they offer the 100,000 mile powertrain warranties. However, we’ve found that just about everything that actually fails isn’t covered, and major engine management components are being rejected for warranty after as little as 60,000 miles.

    DENSO has assembled the most concise system and monitoring explanations, and developed the tests that get you the best results with the least effort. With this information you can "think" your way through diagnostics to beat the flowchart.

    Hyundai & Kia Air Management & Emissions Systems (KEP2)

    Progressively better styling and a consistently low price have finally gained Hyundai and Kia some serious market share. While the return on the time/money invested in receiving specific Hyundai and Kia training has been questionable in the past, we think it's time to take a deeper look for a few reasons:

    • Hyundai and Kia have some very unique solutions to engine management challenges
    • OE Scan Tools are now very reasonable, and aftermarket tools more capable than ever
    • The Hyundai and Kia OE repair websites are free and accessible to everyone, but the system descriptions are general, and the flowcharts are more linear and time-consuming than most

    Ford Powerstroke Engine Performance (6.0L & 6.7L) (PEP)

    Most available powerstroke information is simply reprinted and rearranged OEM information mixed with some field research. While helpful, this strategy mostly repeats the linear diagnostic process found in all OEM information. Considering how much time it takes to diagnose and repair powerstroke engines, this traditional linear approach could cost you hundreds in un-billable time. That’s why we've built this manual and training seminar to give you ways to peel in quickly to the actual fault without wasting time or guessing with expensive parts. Like our General Motors Duramax Training Manual, this powerstroke product has been assembled using actual diagnosis and repair of a wide variety of engine management, emissions, and trouble code faults. We've included pictures, Scan Tool captures, Lab Scope waveforms and much more from simple tests to full tear-downs. Powerstroke engines are known for two things:

    • Trouble codes that DO NOT directly point to the fault
    • Unpredictable interactions between components that make it difficult to even determine which system is the source of the fault

    These two factors make powerstroke diagnostics a real guessing game, but we’ve included all the tips and shortcuts you need to avoid the most common misdirection. Additionally, we’ve documented the many hidden secondary faults that result in unplanned repairs being necessary before the vehicle can be returned to service.

    Powerstroke engines have many expensive problems and can take days to repair, but armed with the information in this manual and seminar you can unlock the opportunities presented by this drivetrain. Systems covered include:

    • Mechanical issues, including lifters, cylinder heads, and common leaks
    • Low and high pressure oil systems, including shortcuts to quickly differentiate between oil faults, high pressure leaks, injector control issues, and many other causes of the most common complaints: No-starts and hard-starts.
    • The complex relationships between turbo controls and EGR systems
    • Dual sequential turbo systems
    • The newest diesel emissions systems, including Diesel Oxidation Catalysts (DOC) and Diesel Particulate Filters (DPF)
