Automatic Dimming Inside Mirror Test

Automatic Dimming Inside Mirror Test

1. Disconnect the 6P connector (A).





2. Turn the ignition switch to ON (II).

3. Measure the voltage between terminal No. 6 and body ground.

- If there is less than 0.2 V, go to step 4.
- If there is more than 0.2 V, check for:
- Poor ground (G401).
- An open or high resistance in the ground wire.

4. Measure the voltage between terminal No. 7 and body ground.

- If there is battery voltage, go to step 5.
- If there is no voltage, check for:
- Blown No. B5 (7.5 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 transmission range switch in R position.

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