Information For Diagnosis

This manual contains the cable diagrams as well as the individual circuit drawings, operational explanations, and troubleshooting hints for each component required to facilitate the task of troubleshooting. The information is compiled in the following manner:

1. Cable diagrams show the connector positions, etc., on the actual vehicle as well as the harness path.

2. Circuit drawings show the configuration of the circuit with all switches in their normal positions.

3. Operational explanations include circuit drawings of voltage flow when the switch is operated and how the component operates in reaction.

4. Troubleshooting hints include numerous examples of problems which might occur, traced backward in a common-sense manner to the origin of the trouble. Problems whose origins may not be found in this manner are pursued through the various system circuits.

NOTE: Components of MFI, ETACS, ECS, etc. with ECU do not include (3) and (4) above.
