My problems started with Door Ajar. Then door ajar, pinging, dome lights, driver window and power lock button in-op, and door lock solenoid cycling continually unless manually locked.
Occasional low beam message and light out.
Door panel removal reveals bad wire ribbon connection. Private garage suggests buying used DDM and try to replace, download software patch or reload. What Diagnosis system or tool do you recommend and what troubleshooting do you suggest?
