Does anyone know the process of re-programming the Tire Pressures in the rear tires of an 07.5 lmm 2500? I know you use the Tech 2 programmer, my local dealer wont do it but the service tech there said he would. He cant find the route through the CPU to do it but if I know the route he will do it!!! I appreciate any help! The reason that I cant have the dealer do it is there is a GM bulletin out to tell the mechanics not to do it...Thanks again for the input!

Diesel07: Do a search on the threads, there was a recent thread discussing this as well as issues relating to this vis-a-vis the dealer, the government, etc..........some dealers will do it, others shrug their shoulders not understanding the request, and the remaining won't. Maybe someone here stood along side a tech with a Tech 2 who watched it being done. Good luck, I hope to change (lower) the TPM thresholds as well.

Thanks for the reply, If I get it figured out I will let you know!
