SSM 53894

Some 2022-2025 Transit vehicles equipped with a 360 degree camera may exhibit one camera display inoperative with diagnostic trouble codes (DTCs) B12BE:31, B148E:31, B12BF:31 and B115E:31 stored in the image processing module B (IPMB). These DTCs will set when only one camera has the condition. Replacement and/or reprogramming of the IPMB will not resolve this condition. To properly identify which camera/circuit has the condition and requires repair, visually confirm which camera display is inoperative (grayed out/blank/blue). If the condition is intermittent, interview the customer to find out more details and/or review the DTCs stored in the IPMB. The DTC with a status byte of 2F (example: B12BF:31:2F) indicates which camera/circuit has the condition. Repair as necessary. Refer to the Workshop Manual (WSM), Section 413-13C.
