Remote started my truck the other day, got in and 4wd will no longer work. VIC says “Service 4wd System” and I am unable to select anything other than 2wd, zero response from all other buttons.
Scanned the codes and came up with C140A-12 “transfer case motor control-circuit shorted to battery”. I had checked all connections at the front axle disconnect, transfer case and dtcm and found nothing loose or corroded.
Can’t find much info regarding this issue, and the closest dealer is nearly 3 hours each way. And in the dead of winter in northern Ontario the last thing I want to do is bring it in for diagnosis and then repair without the use of 4wd.
Anyone have any ideas?
I found this tsb, which is to check dtcm connections which I have done. Will clear the codes in the morning and test afterwards.
