Automotive Training Group: Duramax Diesel Engine Performance
-(Johnson City and Knoxville Markets Only)
Diesel engines are very simple – just compress some air and fuel and you get combustion. However, with the advent of common rail fuel pressurization and delivery systems, diagnosis and repair became a complicated and time-consuming game. Add variable vane turbochargers, feedback EGR systems, and exhaust after treatment systems like Diesel Particulate Filters, Selective Catalyst Reduction, and Diesel Exhaust Fluid injection, and it’s hard to know where to start. System, code, and system diagnosis covered in this seminar includes:
• Finding elusive internal fuel leaks
• Great vacuum-side fuel system tests
• Common mechanical issues
• Modifications & retrofits that make sense
• Tips for getting DPFs to regenerate
• Help for stuck DEF messages and codes
• New pressurized fuel return
• Simplified no-start & hard-start diagnostics
• Variable Vane Turbo issues & diagnosis
Other published Duramax repair information is inconsistent, and many of the flow charts run you in circles performing tests that would actually take days to complete. In contrast, our approach looks for high-level indicators to make a better possible-cause list and then offers multiple simple tests to trim that list as quickly as possible without taking too much apart.
Duramax coverage includes special tools, workarounds, unused Scan Tool functions, and other great shortcuts for ruling out time-consuming tests. From a simple high-level pass to system-specific tips, this seminar covers the entire diagnostic process. We have included dozens of real-world examples to prove that these strategies will find the root cause of your code or symptom in the shortest amount of time.
Automotive Training Group: Evaporative Emissions Systems
-(Chattanooga and Nashville Markets Only)
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 un-billable)diagnostic time or multiple trips for your customer.
This is the 2ndsubject 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 system-specific 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)
At the manufacturer and system-specific layer, Scan Tool PIDs and controls are inconsistent. While we cover them all for you, we also discuss the back-up plans that may involve a power probe, jumper wires, a gas analyzer, Mode $06, or other simple tools and methods to get your EVAP system to give up its secrets.
From a simple high-level pass to system-specific tips, this seminar covers the entire diagnostic process.We have included dozens of real-world examples to prove that these strategies work quickly on the vehicle’s first trip into your shop. We are confident that this seminar will enable you to be a lot more successful in finding leak or flow codes, and in verifying proper component functionality.
February 2018 Classes:
Automotive Training Group: Safety And Accessories System Diagnostics

Several case studies help attendees learn from specific problems that have been experienced and successfully resolved. Includes: Tire Pressure Monitoring Systems (TPMS), various Theft Deterrent and Security Systems (SKIS, PATS, PASS-Key & PASS-Lock, & Immobilizer), Steering Systems & Electric Power Steering, ABS & Traction Control Systems, SRS Occupant Detection, and Power Window Module relearning.
• Tire Pressure Monitoring Systems (TPMS)
• Security (PATS, SKIM, Immobilizer, etc.)
• Instrument Panel Clusters (IPC)
• PCM controlled charging systems
• Power window relearning
• Steering Angle & Yaw sensor relearning
March 2018 Classes:
Garage Gurus: Diagnosing Variable Valve Timing
This class will focus on the different types of variable valve timing (VVT) systems used by vehicle manufacturers today. After multi-valve technology
became standard in engine design, VVT became the next step to enhance engine output, increasing engine power and torque output along with reducing emissions. Without VVT technology, engineers previously had to choose the best compromise in valve/cam timing and ended up sacrificing one thing to gain in another area. VVT allows the best of both worlds' increased performance and economy and lower emissions. There are a multitude of Diagnostic Trouble Codes (DTCs) that can set related to VVT faults stemming from oil contamination to inoperative cam actuators and oil control solenoids. We will explain the variations of VVT systems used by manufacturers today and look at diagnostic tests that can be performed on this system using the scan tool and other diagnostic equipment to confidently diagnose these systems before the costly and labor intensive engine teardown for service.
After completing this seminar, the student will have the knowledge to:
• Identify the VVT system types used by manufacturers
• Understand the VVT DTC stored in the Powertrain Control Module (PCM)
• Relate to the scan tool parameters used by various manufacturers to validate camshaft control and operation
• Realize the importance of lab scope testing to validate camshaft to crankshaft correlation
• Perform mechanical engine tests with a variety of test equipment to avoid timely engine tear downs for diagnostic purposes
• Utilize new scan tool information and techniques to reduce diagnostic time in the service bay for VVT related faults or symptoms
