The Anti-Lock Brake System (ABS) motor relay built into the Skid Control ECU (Brake Actuator Assembly) supplies the power to the ABS Pump Motor. While the ABS is activated, the Skid Control ECU (Brake Actuator Assembly) turns the motor relay ON and operates the ABS pump motor. If the voltage supplied to the motor relay is below the Diagnostic Trouble Code (DTC) detection threshold due to low voltage from the battery or alternator, these DTCs may be stored.
