this product. It
is a part of a total product support
program.
The manual is organized so that all the information on a
particular system is kept together. The order of grouping
is as follows:
• Table of Contents
• General Diagnostic Information
• Specifications
• Electrical Wiring Harness Legend
• Component Location
• System Schematic
• Wiring Harness
• Troubleshooting Chart
• Theory of Operation
• Diagnostics
• Tests & Adjustments
• Repair
Note: Depending on the particular section or system
being covered, not all of the above groups may be

Each section will be identified with a symbol rather than a

numbered.
Headings
in each section
indicate
the
job being
performed. A heading with no model designation applies
