  1. Faulty Actuator: The actuator is a component that is responsible for controlling the movement of a specific part of the vehicle, such as a door lock or a mirror. If the actuator is faulty, it can cause the B173D code to be triggered.
  2. Wiring Problems: Wiring problems can also cause the B173D code to be triggered. This can include damaged or corroded wires, loose connections, or incorrect wiring.
  3. Faulty Body Control Module (BCM): The BCM is the vehicle's onboard computer system that controls a variety of functions, including the actuator circuit. If the BCM is faulty, it can cause the B173D code to be triggered.
