C0612Right Park Brake Actuator Control Circuit High

The C0612 code indicates that the electronic brake control module has detected an abnormally high voltage on the control circuit for the right-side park brake actuator, which is the electric motor that applies the parking brake on that wheel. This high voltage condition typically means the circuit is open, shorted to power, or the actuator motor has failed, preventing proper park brake operation.
