If you replaced it just be sure the battery was unhooked. I left Mopar in 2011 but what they did then was had the cluster as back-up for the TIPM. Both of them basically stored all the vehicle info and options and when you power the TIPM back up after being replaced it should get all the right info over the Buss circuit from the Cluster since that also stores the vehicle info. Now if you replace the cluster and TIPM at the same time then you have to go on line with the truck hooked up to Mopar and download the trucks info from Mopar by the VIN. I had to do that once when I got a Durango that was hit by lightning. Funny as I remember it took out all the Computers on the truck and all the pressure sensors like the MAP , Trans line press sensor , AC press transducer and so on. Ron
