C2005 Code: Meaning, Causes, and Symptoms | OBD2 Codes
C2005 – Right Actuator
C2005 Possible Symptoms
Anti-Lock Brake System (ABS) Warning Light ON,Engine Light ON (or Service Engine Soon Warning Light)
C2005 Possible Causes
Faulty Right Actuator,Right Actuator harness is open or shorted,Right Actuator circuit poor electrical connection,Faulty Anti-Lock Brake System (ABS) Module
When the Anti-Lock Brake System (ABS) Module receives a parking brake apply or release request, the ABS module sends voltage to the parking brake actuator motors. The ABS module also monitors the current draw of the actuator motors to determine when the brake pads contact the brake disc, to determine when the appropriate amount of clamping force is being applied to the brake disc and to determine when the brake pads are retracted to their start position. The ABS module runs self-tests before, during and after an apply or release request. These self-tests are done to determine parking brake system functionality. High actuator motor circuit resistance, a short to ground, a short to voltage, an open circuit, a mechanical or electrical failure of the actuator motor or an internal failure of the ABS module may cause one or more of these self-tests to fail resulting in the ABS module setting one or more Diagnostic Trouble Codes (DTCs).
