Open or Short Circuit in ABS Motor Relay Circuit (C0273/13)
DESCRIPTION
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 ...
