3.
Refer to Component Parts and Harness Connector Location for the Systems described in each
section for identification/location of components and harness connectors.
4.
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 Wiring Diagram in each individual section and Harness Layout in EL
section for identification of harness connectors.
5.
When checking circuit continuity, ignition switch should be OFF.
6.
Before checking voltage at connectors, check battery voltage.
7.
After accomplishing the Diagnostic Procedures and Electrical Components Inspection, make sure
