2.

CHECK BACK DOOR OPENER SWITCH OPERATION

1. Turn ignition switch OFF.

2. Disconnect back door opener switch connector.

3. Check continuity between back door opener switch terminals 1

and 2.

Is the inspection result normal?

YES

>> GO TO 3

NO

>> Replace back door opener switch.

3.

CHECK BACK DOOR OPENER SWITCH GROUND CIRCUIT
