Steering Angle Sensor calibration?

[B2sdad]

Hey there Guys,

Need some guidance. Is anyone in here that happens to have a GM Tech II scan tool and live in the Austin Texas area? I need to check/recalibrate my steering angle sensor? After an alignment I am getting traction control/ Service Stabilitrak light on my dash. The alignment shop for some dumb reason does not have the abilty to reset the sensor. I have a fowell NT716 Scanner that has a SAS recalibration function, but my vehicle isnt supported...????

There are quite a few members that have a Tech 2 and there are always people who wish they had one to use so I thought I would post this thread to try and help each other out. If you own a Tech 2 and would be willing to help out another forum member that might be local to you then post up your...

Following. Didn't know it could be recalibrated so if it can be, I need to do it on my 2007. I replaced it with a new one last year and didn't get it right on the install.

awesome thank you Joseph!

So I just went out to my 2007 with my Tech2 to calibrate the steering angle sensor and there is no such option in the Tech2 for these trucks, apparently.

The Tech 2 Paths Document shows paths for the steering angle sensor positioning, but that does not mean that it is accessible on every year/model truck.

Yep, the electronic brake control module is where I was looking for the special function. I could see the angle being reported by the sensor in the data display screen and it was 37º off with the wheel pointed straight ahead, but there was no option for calibration under special functions.

Well there is where the problem for me seems to be. There are many references to resetting your steering angle sensor after an alignment. Many of them seem to have been done with aftermarket OB2 scanners. I am under the assumption that the GM scan tool of that era is or was able to relearn/reset the sensor? I’m sure it was done at dealerships after alignments were performed? Funny thing is I can’t seem to locate anyone that knows how to do it?

I would bet that just a simple alignment would not require a sensor recalibration...
Unless it was an accident or some very major front end mishap. Or maybe steering wheel
repair of some sort.. Prob why it's not on the tech II..
I have an aftermarket Autel but I've never looked to see if it's capable as I haven't run
into this with any of the cars I work on (yet)

Anyone have any input on this?

I have a 2009 Tahoe LTZ my stabilizing traction light came on and I replace the angle sensor that's what the scanner told me it was bad and I still have the light on and nothing showing up on my scana to anymore but the light is still on

 

[bigboy215]

2009 Tahoe LTZ stabilized and traction light on change the angle sensor and light still on check wheel bearings sensors and they are good and now there's no code on my scanning machine showing and it's still on I don't know what to do do anybody have a clue

Are you using a scanner that can read those codes? Lots of inexpensive scanners don't read them.

What was the original code that led you to replace the SAS?

Okay I appreciate that

I don't remember the clothes right now but I had the truck to the dealership and they tell me the angle sensor was bad and I had to second mechanic and he told me the same thing he said the angle sensor was bad so I replaced that and still have the light on
