Normal Operation
When the transmission is placed in REVERSE (R), the powertrain control module (PCM) sends a signal to the smart junction box (SJB) over the communication network. The SJB then provides voltage through circuits 1362 (DG/OG) and 1367 (WH/YE) to the LH and RH reversing lamps, respectively. Ground for the lamps is provided through circuit 1205 (BK).

DTC B2525 - sets when the SJB detects an open or short to ground on the LH reversing lamp voltage supply circuit.

DTC B2532 - sets when the SJB detects an open or short to ground on the RH reversing lamp voltage supply circuit.

Possible Causes
- Circuit 1205 (BK) open
- Circuit 1362 (DG/OG) open or short to ground
- Circuit 1367 (WH/YE) open or short to ground
- SJB
