Most Reported On
C2005 is an OBD-II diagnostic trouble code meaning “Right Parking Brake Actuator Circuit.” A chassis code, most commonly documented on Ford vehicles with an electronic parking brake, indicating the ABS or EPB control module detected a fault in the right-side parking brake actuator motor circuit. The motor is either mechanically jammed, has a wiring fault, or is not responding to apply/release commands. Symptoms include a parking brake warning light and an EPB that will not fully apply or release; service braking is normally unaffected. Sub-codes narrow it down: :11 short to ground, :12 short to battery, :13 open circuit, :15 short to battery or open, :31 no signal, :92 performance or incorrect operation. C2006 is the same fault for the left-side actuator. This code is most commonly reported on 2014-2022 Land Rover Range Rover Sport, and 2016-2020 Mazda CX-5 (Touring, Grand Touring, Signature), with repair costs ranging from $150 to $900.
