ELECTRICAL OTHER SYSTEM (DCMD)
Hi, here is what happened to me today. Truck came in with a complaint that driver window,

door lock, dome light and mirror adjustment not working.
First thing I've done was to disconnect battery for a good 5 minute. Not working.
Second, connect with DL8, no fault code. Get into the windows template screen, then | noticed

that the "return control to vehicle button was clickable", | hit it. Dome light turn ON, and

everything on that switch panel has come back. Wasn't able to duplicate trouble after that.
An other computer issue to my mind. How to explain it? I'll try to pay attention for future

comeback for that truck.

Is there any water intrusion at Deutsch connector, inside the door. Usually causes AAT

codes. S¢NEW CASCADIA MIRROR AAT CODES has some pictures of the connector and
where the water comes from.
