If there is continuity:
- To specify the malfunctioning location, go to the next step. If there is no continuity:
- There is no short between circuits, therefore the inspection is completed.

Refer to the wiring diagram and verify if there is a common connector between the applicable circuits.

If there is a common connector:

Disconnect the common connector and inspect the connector and terminal. (See CONNECTOR INSPECTION .)

Inspect each common connector for continuity to determine the malfunctioning location.
