ABS (Antilock Brake System)

DTC C0274/14 Short to B+ in ABS Motor Relay Circuit

DESCRIPTION

DTC Detection Condition:

The ABS motor relay supplies power to the ABS pump motor. While the ABS is activated, the ECU turns the motor relay on and operates the ABS pump motor.

If the voltage supplied to the motor relay (+BM) is below the DTCs detection threshold due to low voltage from the battery/alternator, the DTCs may be stored.
