2006 Ram No 4Wd Operation And No Codes
Got a 2006 dodge ram 1500 (non srt10 or power wagon) originally came in with all lights on dash and nothing working, found tipm had lost vin and programing. Used witech and recovered vin and programming and now everything operates with no codes except no 4wd operation and no codes for 4wd. I Can see the 4wd knob input to cluster, then cluster sends that info over can network to tipm( cant find any pids with snap on, autel , or witech that show 4wd message leaving cluster or getting to tipm). I can control transfer case motor from plug at tipm and when I do the cluster responds buy turning on or off the appropriate light which it is recieving from tipm, there are no bi directional controls in cluster or tipm for 4wd. My question is how do I test if the cluster is sending out info and if the tipm is receiving info, I think the driver for transfer case motor in the tipm is the problem and I know tipms are common problems but like to have proof before I pull the trigger on a $1400 part.
