DTC C0278/11 Open or Short Circuit in ABS Solenoid Relay Circuit: Description
WARNING: This page is about a different car, the 2009 Toyota Sequoia. However, it is still accessible from the selected car via links, so may be relevant.
The solenoid relay (skid control ECU interior circuit) supplies power to the ABS solenoid and TRC solenoid.
After the ignition switch is turned ON, the vehicle speed has reached 23 km/h (14 mph) 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.
This DTC may be set if the voltage supply to the solenoid relay (+BS) falls below the DTC detection threshold due to the battery or alternator outputs being insufficient.
