Vehicle Stability Control System (For BOSCH Made)

DTC C0273/13 Open or Short Circuit 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 switches 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 or alternator, the DTC may be stored.
