GM/Detroit 6.5L – General Information – COURSE OVERVIEW

The focus of this booklet and its related two-day course is electronic fuel system operation and diagnosis on the 6.5L EFI V8 diesel engine (figure 1 -1). This course is intended for technicians who have diesel engine mechanical experience, but who may be less familiar with electronic engine management systems and โ€œScanโ€ tool diagnostics.

Because the Powertrain Control Module (PCM) is such an integral part of fuel system management, and because it is new to diesel applications, a great deal of time will be devoted to PCM operation and diagnostics. Every attempt will be made to present this new information within the context of existing 6.5L V8 knowledge and experience.

This course also includes numerous studies intended to provide hands-on implementation of the diagnostic strategies, especially โ€œScanโ€ tool usage.
