Service StabiliTrac, Service Traction Control, but no Reduced Engine P

2009 Silverado 1500 Z71 4x4 Crew Cab, 84,000 miles.

 

Lately I've been having an issue where the DIC chimes and I see Service StabiliTrak, Service Traction Control come across the screen. Unlike alot of people the truck doesn't enter Reduced Engine Power mode and it seems to run and drive just fine. 90% of the time it will only do this when it is cold outside, under 40F. Any suggestions on what could be going on? Is it the throttle body issue?

Steering wheel position sensor can cause this. There will be codes the dealer can pull for that sensor (or if its the throttle body sensor) that will narrow it down.

Thanks, its going in on Friday so they can look at it. Getting tired of seeing the warning messages come up.

When mine said that, I was told it had to do with voltage issues. Might be - sometimes I don't drive the truck for 3-4 days and after 4 days I get a low battery warning. Battery reads 11.9 but starts fine.
