Test W: The Reversing Lamps Are On Continuously
PINPOINT TEST W: THE REVERSING LAMPS ARE ON CONTINUOUSLYW1-W2:
W3-W8:
Normal Operation - Automatic Transaxle
When the transaxle is placed in REVERSE, the transmission control module (TCM) sends gear status information to the instrument cluster over the communication network. The smart junction box (SJB) receives transmission gear status from the instrument cluster over the communication network. When the SJB receives a message indicating the transaxle is in REVERSE, the SJB provides ground to an internal relay, which routes the voltage to circuit CBP12 (GN/WH) to the reversing lamps.
Normal Operation - Manual Transaxle
Voltage is supplied to the reversing lamp switch through circuit CBP18 (GY/OG). When the transaxle is placed in REVERSE, the reversing lamp switch routes the voltage to circuit CBP12 (GN/WH) to the reversing lamps.
Possible Causes
- Circuit CPB12 (GN/WH) short to voltage
- Reversing lamp switch
- Rear view mirror
- Instrument cluster
- SJB
