It does read codes from all the modules, clears DTCs and resets service reminder. It helped me track down a problem with my door lock and key remotes not working so it's already paid for itself. Doesn't take long when compared to the cost of going to the dealer.
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?
