CUSTOMER CONCERN The display switches to the reverse-camera screen, but no camera image appears. Replacing the camera did not correct the concern. CAUSE Voltage and continuity testing confirmed damaged backup-camera wiring in the tailgate circuit. CORRECTION Repair the backup-camera wiring in the tailgate circuit.

CUSTOMER CONCERN Customer states the ABS and brake warning lights are on and the ABS pump runs repeatedly. DTC C1391 is stored. CAUSE No external brake-fluid leak was found, and accumulator pressure dropped after pump shutdown, confirming internal leakage in the ABS brake actuator. CORRECTION Remove and replace ABS brake actuator assembly. Perform actuator initialization and complete brake-system bleed, clear DTC C1391 and verify accumulator pressure holds.
