I have a 2009 Silverado Crew Cab 4X4 with a 5.3. I have been getting a Servive Stabilitrak indication repeatedly and I cannot figure out the cause. Whenever it happens I have to disconnect the battery and discharge all power to reset it so I can Drive it again. I usually only experience it whenever I try to accelerate quickly (barely). I have been getting it more frequently lately without much acceleration. I am able to duplicate the issue by simply revving the engine maybe half throttle. Also without the engine running if I press the throttle it will come on. I have changed the TPS but the problem continues. I have also checked to ensure ABS connections are good. Any help would be greatly appreciated.

 

the reduced engine power fault is throttle body or accelerator pedal position related; it will set a dtc so have it read and post it here.
the stabilitrac will be disabled due to the reduced engine power fault. fix the first problem and the stabilitrac will work normally.

 

Is your check engine light on?

 

After having the issue continue without the ability to reset by disconnecting the battery like I had done previously, I disconnected and reconnected the accelerator. Since then I have not been able to duplicate the fault. I hope that it was indeed that easy, but I still drive it expecting at anytime it will pop back up. Either way, I will post again later about whatever happens. Thank you for the help!

 

how and where did you disconnect and reconnected the accelerator. Where is the connector located? I'm having stability service issues as well. Only when I apply throttle. Thanks.

 

I disconnected wire harness from the pedal. Hopefully that is in fact all the problem. I have tried now for the past 6 days to duplicate the fault but it's still working normal.

 

Thanks for the info and pic. Will try and hope it gets rid of that annoying stabilitrak.
