Test W: The Reversing Lamps Are On Continuously

PINPOINT TEST W: THE REVERSING LAMPS ARE ON CONTINUOUSLY

Normal Operation - Automatic Transaxle
When the transaxle is placed in REVERSE (R), the transmission control module (TCM) sends gear status information (through the instrument cluster [IC] gateway) to the smart junction box (SJB). When the SJB receives a message indicating the transaxle is in REVERSE (R), the SJB provides ground to an internal relay, which routes the voltage to circuit CBP12 (GN/WH) to the reversing lamps and the electrochromatic rear view mirror (if equipped).

Manual Transaxle
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
