2009 Chevy Tahoe Issues
 

Hey all,

I'm having a few issues with the Tahoe. Below is what's happening.

1. ABS light, Service 4wd, traction control lights come on.
2. Fuel, Oil and engine temp gauges go down.
3. Vehicle won't go shift out of first gear.
4. Turning the vehicle off, waiting 5 minutes and turning it back on seems to fix it.

Any ideas?

Thanks in advance!

Pcm?
 

Hello I 2 was having similar but not quite the same issues. I recently swapped the PCM(Power Control Module) on my 2003 Tahoe because I was having other thing go out on me. I did some researched and what I found were signs of the PCM going out. Maybe check to see if you are getting corrosion on the pins. MY truck is currently not starting at all even checking all the usual things (Gas, Power and Starter).
