Diagnosis Procedure

Check steering angle sensor mounting condition. Refer to "EXPLODED VIEW ".

Is the inspection result normal? 

YES: GO TO 2.

NO: Repair or replace error-detected parts.

1. Turn the ignition switch OFF.
2. Disconnect steering angle sensor harness connector.
3. Check voltage between steering angle sensor harness connector and ground.
