Operation CHARM: Car repair manuals for everyone.

Diagnostic Charts Usage

The diagnostic charts are used to find and repair Malfunctions which the self-diagnostics have found. These can be:
1. Charts which locate a display Malfunction that keeps the technician from using the on-vehicle diagnostics.
2. Charts where a Diagnostic Trouble Code (DTC), Driver Information Center (DIC) message, or combination of both leads you to a particular Malfunction.
