Dash Board Problem

[raygray]

I'm having a problem with the dash board functions on a 2004 Chevy Suburban.

I've been to the dealer 3 times and he is unable to locate the problem and I'm hoping someone has had a similar experience.

First, the ServiceTireMonitor message light is on and they can't disconnect it.
Replacing the tire sensors did not solve the problem.

In addition, the gas guage goes way over full and the temperature guage shows way beyond hot and the car is not hot at all.

Could these three problems be related to some digital board or something.

And, I also have a radar detector and a remote control start ( by Python ) --- could either of these devices create this problem.

Hope someone can help. Thanks in advance.

Welcome! From what you describe, it nearly has to be some electronic component that is effecting "all of the above". It sure looks like a GM dealer should be able to trace it down. Wish I could help, but good luck!

If you use your signal lights, do the gauges go up en down?
If this is the case then you have a problem with the ground connection
