Manual Transaxle
WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
Voltage is supplied to the reversing lamp switch through circuit CBP18 (GY/OG). When the transaxle is placed in REVERSE (R), the reversing lamp switch routes the voltage to circuit CBP12 (GN/WH) to the reversing lamps and the electrochromatic rear view mirror (if equipped).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Reversing lamp switch
- Rear view mirror
- SJB
