Fault Diagnosis With the Aid of Wiring Diagrams

INTRODUCTION
On the following pages we will explain how the wiring diagrams are compiled.

SERVICE CATEGORIES
The wiring diagrams are divided into different system groups. The division in this manual has been adapted to the division that applies in other manuals and in WIS:
1 Service
2 Engine
3 Electrical system
4 Transmission
5 Brakes
6 Steering system
7 Suspension, wheels
8 Body

The wiring diagrams within the groups in each service category are arranged in ascending order.

For example, the first wiring diagram in the group Engine is "Trionic Engine Management System" and the last one is "Radiator fan".

A complete list of all systems, arranged in service category order, can be found on the next page.
