Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello my name is***** am an ASE Master Technician and I am glad to help you with your question.
Here is a diagram of how the system works. This could be a problem with the vehicle security module or VSM.
Please reply to this if you need more help and we can continue this conversation at no extra charge. This does not have to be my only answer. If you are satisfied with my service, please rate at the top of the screen. Rating does not close out your question. Remember, sometimes it is difficult to completely diagnose your vehicle without being there, but I will try to give you the best answer I can. Hoping to be giving you 5 star service.
With a scan tool that can access this module, there may be codes in the VSM that is the first step.
Also check the liftgate ajar switch and the liftgate glass ajar switch.
Have you checked for voltage at the door switches? Not all scan tools can access the VSM you need a dealer quality scan tool for this.
Yes use a volt meter.
If there is voltage, check the switches with meter set to read ohms. If switches are good, then check the grounds.
The grounds are labeled in the wiring diagram I sent you. At the bottom right of the diagram.
Ok let me know if you have any more questions. thanks.
