DTC C0279/12 Short to B+ in ABS Solenoid Relay Circuit

DESCRIPTION

DTC Detection Condition:

The ABS solenoid relay supplies power to the ABS solenoid and TRAC solenoid.

The solenoid relay is turned on 1.5 seconds after the engine 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 actuator assembly.

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