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 brake-actuator leakage. CORRECTION Remove and replace ABS brake actuator assembly. Perform actuator initialization and brake-system bleed. Clear DTC C1391.

CUSTOMER CONCERN Customer states the engine overheats and coolant leaks from the radiator area. CAUSE Inspection identified the larger radiator nearest the engine as the leaking engine-cooling radiator. CORRECTION Remove and replace engine radiator. Refill and bleed engine cooling system and verify no coolant leaks.

CUSTOMER CONCERN Customer states brake pressure was lost at the right rear after rear brake and caliper replacement, and conventional bleeding did not restore the pedal. CAUSE Air remained trapped in the electronically controlled brake system and the hydraulic pump required scan-tool activation. CORRECTION Operate brake pump and perform complete hybrid ABS bleed procedure with a compatible scan tool. Verify brake-pedal pressure.
