Normal Operation
Under normal operation the auto-dimming mirror receives power from circuit C_CBP18 (GY/OG) and ground from circuit GD133 (BK). If the vehicle is placed in REVERSE, voltage is sent to circuit CBP15 (BN/DB) and the auto-dimming mirror will turn the dimming feature OFF.

Possible Causes
- Open in circuit C_CBP18 (GY/OG), GD133 (BK) or CBP15 (BN/DB)
- Inoperative auto-dimming mirror.
