DESCRIPTION
While driving at night, if a large difference exists between the intensity of the light surrounding the vehicle and the light entering the inside rear view mirror (typically from the vehicle headlamps behind your vehicle), this system automatically reduces the reflection rate of the mirror.
The reflection rate of the outside rear view mirrors varies in accordance with the change in the reflection rate of the inside rear view mirror.

- INSPECT INNER REAR VIEW MIRROR ASSY Check operation of the electrochromatic inner mirror. Connect the battery positive (+) lead to terminal 1 and the negative (-) lead to terminal 4. Attach black colored tape to the forward sensor to prevent it from sensing. Shine an electric light on the mirror. Check that the mirror surface changes from bright to dark. If the result is not as specified, replace the mirror assy.
- INSPECT OUTER REAR VIEW MIRROR ASSY LH Disconnect the mirror connector. Apply battery voltage to the mirror and check operation of the mirror face. OK: MEASUREMENT CONDITION SPECIFICATIONS Measurement Condition Specified Condition Battery positive (+) --> Terminal R39-7 (EC+) Battery negative (-) --> Terminal R39-15 (EC-) Mirror surface darkens If the result is not as specified, replace the mirror assy.
- INSPECT OUTER REAR VIEW MIRROR ASSY RH Disconnect the mirror connector. Apply battery voltage to the mirror and check operation of the mirror face. OK: MEASUREMENT CONDITION SPECIFICATIONS Measurement Condition Specified Condition Battery positive (+) --> Terminal R40-7 (EC+) Battery negative (-) --> Terminal R40-15 (EC-) Mirror surface darkens If the result is not as specified, replace the mirror assy.
