Automatic Dimming Inside Mirror Test/Replacement

1. Remove the roof console front cover.

2. Disconnect the 6P connector (A) from the automatic dimming inside mirror (B).





3. Check for continuity between terminal No. 6 and body ground.

- If there is continuity, go to step 4.
- If there is no continuity, check for:
- An open or high resistance in the ground wire.
- Poor ground (G601).

4. Measure the voltage between terminal No. 4 and body ground with the ignition switch turned to ON (II).

- If there is battery voltage, go to step 5.
- If there is no voltage, check for:
- Blown No. 21 (10 A) fuse in the driver's under-dash fuse/relay box.
- An open or high resistance in the wire.

5. Measure the voltage between terminal No. 5 and body ground with the ignition switch turned to ON (II) and the transmission range switch in R position.

- If there is battery voltage, replace the mirror assembly.
- If there is no voltage, check for:
- An open or high resistance in the wire.
- Faulty driver's under-dash fuse/relay box.
- Faulty transmission range switch.
- Poor ground (G101).
