Automatic Dimming Mirrors Test

1. Turn the vehicle to the ON mode. Measure the voltage between terminal No. 7 and body ground.

• If there is battery voltage, go to step 3.
• If there is no voltage, check for:

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 voltage more than 0.2 V, check for:
• • -

    An open or high resistance in the ground wire

  • -

    Poor ground (G401)

Measure the voltage between terminal No. 5 and body ground with the shift lever in R position/mode.

• If there is battery voltage, replace the rearview mirror .
• If there is no voltage, check for:
• • -

    An open or high resistance in the wire

  • -

    Faulty under-dash fuse/relay box

  • -

    Faulty reverse relay circuit

  • -

    Faulty transmission range switch
