C146c Description

The ABS Motor Relay supplies power to the Pump Motor. While the ABS is activated, the Skid Control ECU turns the ABS Motor Relay on to operate the pump motor. If the voltage supplied to the ABS Motor Relay is too low due to low voltage from the battery or alternator, the Diagnostic Trouble Code (DTC) may be stored.
