Automatic Dimming Inside Mirror Test

Automatic Dimming Inside Mirror Test

1. Check for obstructions (parking stickers, labels, etc.) over the front-facing lux level sensor.

2. Remove the roof console front cover.

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





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

- If there is continuity, go to step 5.
- If there is no continuity, check for:
- An open or high resistance in the ground wire.
- Poor ground (G601).

5. 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 6.
- 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.

6. 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).
