HOW TO FOLLOW TROUBLE DIAGNOSES
Description INFOID:0000000001503192
NOTICE:
Trouble diagnoses indicate work procedures required to diagnose problems effectively. Observe the following
instructions before diagnosing.
• Before performing trouble diagnoses, read the “Work Flow” in each section.
• After repairs, re-check that the problem 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.
• When checking circuit continuity, ignition switch should be OFF.
• 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-har-
ness is used, refer to Wiring Diagram in each individual section and Harness Layout in PG section for identi-
fication of harness connectors.
• Before checking voltage at connectors, check battery voltage.
• After accomplishing the Diagnosis Procedures and Electrical Components Inspection, make sure that all
harness connectors are reconnected as they were.
