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

Toyota Corolla Cross (2022-2025) Service Manual / Brake / Brake Control / Dynamic Control Systems / Electronically Controlled Brake System (for Gasoline Model) / 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.	Detection Item	DTC Detection Condition	Trouble Area
C13C012	Brake Pressure Control Solenoid "A" Control Circuit Short to Battery	A short to +B in the master cylinder cut solenoid circuit is detected during the self test.	Skid control ECU (brake actuator assembly)
