DOOR LOCK TIMER UNIT INSPECTION

id091400830200

1. Measure the voltage at each terminal (other than terminals 1E and 2W).

  • If not as specified, inspect the parts listed under "Inspection item (s)".

2. Disconnect the negative battery cable.

3. Inspect for continuity at terminals 1E and 2W as indicated below.

4. Disconnect the door lock timer unit connector and inspect for continuity between terminals 1E or 2W and the bracket.

5. If the parts and wiring harnesses are normal but the system still does not work properly, perform the troubleshooting.
