Aftertreatment 101
Electrical Diagnosis: A Start on Networks - Scan Tool to DLC
Electrical Diagnosis: A Start on Networks - Scan Tool to DLC
As a diesel service manager, service writer, or technician, are you up to date on aftertreatment?
2007 and later diesel-powered vehicles have used aftertreatment systems. This includes Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF) and later models have added a Selective Catalyst Reduction (SCR). These emission control systems have brought about numerous issues and are often come-backs for a drive-in service shop.
In this course, we will be discussing the operation and diagnosis of these systems. Sensors and components will be reviewed. Regeneration will be viewed and discussed with actual case studies from vehicles diagnosed and repaired in a drive-in shop. Discussion will include service information from GM, Ford, and RAM. There will be mention of other makes, but the training will focus on the reality of issues found with the DPF and SCR. DEF fluid can affect the reduction of NOX emissions while the DPF aids in reduction of particulate matter or soot.
Engine driveability issues affect aftertreatment operation. Training will include common maintenance and faults that cause issues with premature aftertreatment failure.

Duramax L5P Introduction
Duramax L5P Introduction
Light Duty Diesel Review
The latest model Duramax V8 6.6L engine is the L5P which is the newest diesel offered by General Motors. This V8 diesel is found in the Chevrolet Silverado and GMC Sierra and provides 445 horsepower and 910 foot pounds of torque.
This 1.5 hour webinar will instruct the attendee on the Duramax L5P, its subsystems and how it compares to early LML systems. There will be discussion on the L5D found on medium duty trucks and International applications. This information will include new diagnostic strategies and use of the scan tool. Service information discussion will cover typical Diagnostic Trouble Codes and service procedures.

Duramax L5P Diagnostics
Duramax L5P Introduction
Duramax L5P Diagnostics
Note: This is a continuation of L5P Introduction course.
We will discuss the diagnostic techniques to be used on a Duramax L5P. Diagnosis will require the technician to have knowledge and understanding of the subsystems in this newer L5P Duramax.
Subsystems we will train on are:
- Engine overview, compression and intake - not always a basic thing!
- Denso Common Rail Fuel injection system
- Turbocharger
- Aftertreatment (DOC, DPF and SCR)
Diagnosis will begin by using a basic strategy and continued with the scan tool using diagnostic trouble codes (DTC). Diagnostic Codes to be reviewed will cover fuel timing and aftertreatment. Training will also cover lift pump operation and network communication.
This course will review issues found with injector timing and volume DTCs that can be an issue especially setting after an injector replacement.
Use of the service manual procedures will be demonstrated and emphasized. Scan tool data and screen shots will be demonstrated.

Powerstroke 6.7L Common Rail Testing
Powerstroke 67L Bosch Piezo Common Rail (CR) has challenged the diesel technician in diagnosis.
In this course, we will review the description and operation of the common rail fuel injection system found on the Powerstroke 6.7L engine.
The low pressure, high pressure and return system found on this complete CR system will be discussed. We will use not only fuel pressure tests, but discuss cap and debris inspection as well.
The CP4 injection pump has had issues, which is reviewed, and provide tips to prevent the catastrophic destruction of this pump.
An emphasis on the specific return tests and review of the operation of the volume control valve (VCV) and the pressure control valve (PCV) will be presented.
Fuel filter replacement has been a concern in the life of this CR system. We will review the proper procedures of their replacement.
Service information and use of the scan tool using IDS will be demonstrated.
