Toyota Camry (XV70): Brake Pressure Control Solenoid "A" Control Circuit Short to Battery (C13C012,...,C13C949)

Toyota Camry Repair Manual XV70 (2018-2024) / Brake / Brake Control / Dynamic Control Systems / Vehicle Stability Control System (w/ Electric Parking Brake System) / Brake Pressure Control Solenoid "A" Control Circuit Short to Battery (C13C012,...,C13C949)

DESCRIPTION

The ABS solenoid relay and master cylinder cut solenoid valves are built into the brake actuator assembly.

Depending on the operating conditions, the master cylinder cut solenoid valves regulate the brake fluid pressure generated by the pump motor.

When this DTC is stored, the fail-safe function operates and the ABS solenoid relay is turned off to prevent the master cylinder cut solenoid valves from operating.

DTC No.
