DTC C0278/11 Open or Short Circuit in ABS Solenoid Relay Circuit

DESCRIPTION

DTC Detection Condition:




The ABS solenoid relay supplies power to the ABS solenoid.

The solenoid relay is turned on 1.5 seconds after the ignition switch is turned on (IG), and is turned off if an open or short in the solenoid is detected by self diagnosis performed when the vehicle starts running. The ABS solenoid relay is housed in the skid control ECU in the brake actuator assembly.

HINT: If a speed signal of 4 mph (6 km/h) or more is input to the skid control ECU, with the ignition switch on (IG) and the stop light switch off, the skid control ECU performs self diagnosis of the motor and solenoid circuits.
