Door Lock Circuit Protection
WARNING: This page is about a different car, the 2009 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.
The TIPM controls the door lock relays. If the door lock switch is actuated continuously for more than five seconds the TIPM will turn the output driver OFF (the TIPM would consider the switch stuck). Each lock motor is protected with a Positive Temperature Coefficient device that prevents motor burn out.
