Toyota Corolla Cross: Left Front Wheel ABS Hold Solenoid Control Circuit Short to Battery (C12A512,...,C12B049)
DESCRIPTION
The ABS solenoid relay and solenoid valves are built into the brake actuator assembly.
The front solenoid valve LH controls the brake fluid pressure of the front wheel cylinder LH of the vehicle.
When this DTC is stored, the fail-safe function operates and the ABS solenoid relay is turned off to prevent the solenoid valves from operating.
