NOTE: Before testing, check the No.13 (7.5 A) fuse.

1. Remove the front ceiling light.




2. Disconnect the 3P connector from the mirror.
3. Check for voltage between the No.3 terminal and body ground with the ignition switch ON (II).
- If there is battery voltage, go to step 4.
- If there is no voltage, check for:
- an open in the wire, or
- poor ground (G401, G402).

4. Check for voltage between the No.2 terminal and body ground with the ignition switch ON (II) and A/T gear position in [R].
- If there is battery voltage, replace the mirror by removing three screws.

- an open in the wire, or
- faulty reverse relay, or
- faulty A/T gear position switch, or
- faulty diode.
