Normal Operation
When the powertrain control module (PCM) detects the transmission in REVERSE, a signal is sent to the smart junction box (SJB) over the communication network. Voltage 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
