NOTE: Trouble diagnoses indicate work procedures required to diagnose incidents effectively. Observe the following instructions before diagnosing.

Before performing trouble diagnoses, read the Preliminary Check, the Symptom Chart or the Work Flow.
After repairs, re-check that the incident has been completely eliminated.
Refer to Component Parts and Harness Connector Location for the Systems described in each section for identification/location of components and harness connectors.
Refer to the Circuit Diagram for quick pinpoint check. If you need to check circuit continuity between harness connectors in more detail, such as when a sub-harness is used, refer to Circuit Diagram in each individual section and Harness Layout in SYSTEM WIRING DIAGRAMS for identification of harness connectors.
When checking circuit continuity, ignition switch should be OFF.
Before checking voltage at connectors, check battery voltage.
After accomplishing the Diagnostic Procedures and Electrical Components Inspection, make sure that all harness connectors are reconnected as they were.
