KyAT4

Still haven’t gotten the new TCCM. It’s been over two months that it has been on order. Tonight while the truck was in 2WD the warnings and messages came back. The parking brake also did not want to disengage automatically when putting it in gear and giving a bit of gas.

Any information on what the fix was for this yet? I have a 19 AT4 with the performance package and my Service 4WD light came on randomly when I started the truck in the morning. My wife typically leaves the truck in the Auto AWD setting. When the light came on the truck was acting like it was in 4WD and none of the buttons were working to put it into 2WD. Therefore on dry pavement I had to make it home on a Sunday about 100km and book the truck in. The dealership got the truck into 2WD and said the TCCM transfer case control module needs to be replaced and it could be a while for the part to come in. They said keep the truck in 2WD and do not use 4WD. Well I live in Canada and we had a snow storm last night and I was not pleased to be told not to use the 4WD on a truck a bought 2 months ago. Did a new TCCM fix the issue for anyone?
