C0278

DTC C0278/11 Open in ABS Solenoid Relay Circuit

DESCRIPTION

DTC Detecting Condition:

The solenoid relay supplies power to the ABS solenoid.

After the ignition switch is turned on, the vehicle speed has reached 3 mph (5 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 the DTC detection threshold due to the battery or alternator outputs being insufficient.

HINT: C0278/11 and C0279/12: The skid control ECU begins to detect these DTCs when the vehicle speed exceeds 4 mph (6 km/h).
