Test X: The Reversing Lamps Are Inoperative

PINPOINT TEST X: THE REVERSING LAMPS ARE INOPERATIVE

X1-X3:

Normal Operation
When the transmission control module (TCM) detects the transmission in REVERSE, a signal is sent to the smart junction box (SJB) over the communication network. The SJB then provides voltage to the reversing lamps through circuit 1367 (WH/YE).

Possible Causes
- Circuit 1367 (WH/YE) open
- SJB
