The horrid "service stabilitrak" error....

[Martin Ehlert]

15' GMC 2500HD, 88K, started spitting up this error a few months ago.

Been reading a lot about this in various forums...components include steering, wheel speed sensors, tranny, brakes, throttle peddle position sensor, brake peddle position sensor, on & on & on. From what I understand, it's just a generic code for many possibilities.

I've done my homework for sure and still doing it....but had some time today to follow-up again.

 

I even bought an Autel mk808bt scanner so I'm not afraid to find the problem at "reasonable" cost rather than let the dealer shot-gun parts at it with no results....as I've read.

(Lots of expensive "no results" stories there!)

 

The only code showing is C0710:5A which is "steering position signal not plausible".

Read about the plug corrosion issue and the "do not replace until you do this first" articles too. I played around with that, no different results.

 

I've also read horror stories from going into limp mode to just killing the motor at high speeds on a highway. Friggin crazy!

My problem, lucky to say, is different than most I've read. The error just shows up randomly & goes away randomly maybe 1-2-3 time a day with no ill effect in the trucks performance at all. Nothing. (I have a service station maintenance truck and make many starts & stops daily)

 

I recently had Pitman & Idler arms replaced and steering wheel is off center about 5-10 degree's to the left. However....the error had shown itself prior to that. Had tranny replace many months prior to the error also.

I do understand the steering wheel position sensor is probably just an everyday potentiometer and may be worn down being that I live in the mountains in No Cal wine country. Straight roads around her are few & far in between.

 

So thought to see if anyone has some experience with this scenario before I have to start shot-gunning parts at it myself.

Thanks for your time, appreciated.

Had an intermittent "service stabilitrak" error on my wife's 2008 silverado. Ended up being the connector on the throttle body. Removed and sprayed with contact cleaner and reconnected. Never had the problem again. It's been awhile but I think I was losing the B+ voltage source and it only was used in a few places. One of them being the throttle body.
