Inner Rear View Mirror: Inspection: 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.

1. INSPECT INNER REAR VIEW MIRROR ASSY 
   1. Check operation of the electrochromatic inner mirror.
      1. Connect the battery positive (+) lead to terminal 1 and the negative (-) lead to terminal 4.
      2. Attach black colored tape to the forward sensor to prevent it from sensing.
      3. 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.
