C2006 Code: Meaning, Causes, and Symptoms | OBD2 Codes

C2006 – Left Actuator


C2006 Possible Symptoms


Anti-Lock Brake System (ABS) Warning Light ON,Engine Light ON (or Service Engine Soon Warning Light)


C2006 Possible Causes


Faulty Left Actuator,Left Actuator harness is open or shorted,Left Actuator circuit poor electrical connection,Faulty Anti-Lock Brake System (ABS) Module


C2006 Description


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).
