Service Trailer Tire Pressure Mgmt System

[jeffkirk66]

After setting up the TTPMS it worked well.  Some time later I kept getting a message about a Nav error.  Service tech installed an updated version on the radio and after that my TTPMS system was no longer available.  Service dept can't figure out why!  Any thoughts?

Gotcha. Yeah I think I saw the gm dealers actually have a special tool to program them without the trailer. Did you get it to work?

Which TPMS tool did you buy?

 

No need for a TPMS tool.  There is a manual mode to set up the tires, while connected to trailer and with profile up select TPMS set up, once started, all you have to do is lower or increase pressure in each tire for the set up grid supplied on screen and wait for honk to go to next tire.  Once completed, obviously adjust tire pressure to desired pressures.
