Driving today about 25-30mi into my trip on the highway "serv tpm" message came up on the dash stoped at a gas station for 5-10 min started truck message was gone..did some more city driving stayed off the whole time ,got back on the highway and roughly the same time/distance into my trip the message came up on the dash "serv tpm" the truck has been sitting about 20-30 min now since i got home and the message is still on .. Any thoughts?

 

Dealer will have to replace the TPM (Tire Pressure Monitor) module...Nuttin to it!

 

Now if one were to rotate the tires dont you have to "reset" the tpm?

 

Yes..but all you get is the tire icon to light up, I think

 

check the tire pressure in all 4 tires

 

Just checked tire pressure and the tires range from 31-34 psi thinking about bumping that up another 5 psi...bring them up to 38-40..the tires are 285/75/16

 

Maybe that's all it is then, let us know if the proper tire inflation cured your alarm..

I have the same tires as you, and I always maintain 40 PSI cold in all four, the tires can Handle 50 PSI MAX..(best to keep then all equal too.)

 

I just put on Bridgstone dueler at revo they have a max pressure 65psi...that should be good right!! or should i keep it at 60ish!!

JUST KIDDING!!

 

the serv. tpm is the message you get for low air inflation, no major deal and nothing to worry about...nuttin is broke. You will get the message at each ignition cycle, just hit the trip odometer button once and the message will go off and not reappear until the next ignition cycle. The entire TPS system that GM developed is a waste of time and money, I haven't even had the sensors for three months now and only got the message one time.

 

Yeah Mike, that's because you carry around your stock tires piled in the back..
