Hi all! I'm new to the group and was hoping to get some feedback on my AWD system Disabled issue.. I have tried changing the fluid and Haldex filter in hopes that it may clear out but no luck.. I tried putting a scanner to the truck but showed no Codes at all.. fuse is ok. This issue started a few months ago and at first would be intermittent and is now constantly disabled. Any ideas at all?? 200k miles on it. This has been a great vehicle and would love to get this issue resolved being winter and all... Thanks in advance!!!

Not all scanners can get the Differential Electronic Module (DEM) codes, what scanner did you use? Vida-DiCE recommended.

You can try cleaning the connectors on the Differential Electronic Module.
( Under Truck at the end of the driveshaft, rear axle ).
Check the DEM harness for shorts and opens.
