PINPOINT TEST T: THE REVERSING LAMPS ARE INOPERATIVE

T1-T2:

Normal Operation
The PCM monitors the digital TR sensor. When the PCM detects the transmission is in REVERSE, a signal is sent to the SJB over the communication network. Power from the SJB is sent through circuits 1362 (DG/OG) and 1367 (WH/YE) to the LH and RH reversing lamps respectively. Ground is supplied individually to the reversing lamps through circuit 1205 (BK).

Possible Causes
- SJB
- PCM
