SERVICE TIRE MONITOR message

Is it possible to disable finally the message "SERVICE TIRE MONITOR" ?

Not with HPT

May just need a relearn. Your owners manual should explain how to do it or take it to a tire shop.

I have a 2004 Chevy Tahoe and I looked all through the program and cant find anything to turn it off either. Has anything changed since this post from 2013?

Since TPM on a '04 Tahoe uses the PDM, BCM, DIC & IPC, all modules HPT doesn't access, no.
