C0278 TOYOTA - Open or Short Circuit in ABS Solenoid Relay Circuit
C0278 Toyota DescriptionThe solenoid relay supplies power to the Anti-Lock Brake System (ABS) solenoid and TRAC solenoid.
After the ignition switch is turned on, the vehicle speed has reached 4 mph (6 km/h) and the solenoid is determined to be normal by the initial check self- diagnosis, the relay switches on. If any open or short circuits are detected, the relay switches off.
These DTCs may be set if the voltage supply to the solenoid relay (+BS) falls below the DTC detection threshold due to the battery or generator outputs being insufficient.
