Stabilitrak and Stabilitrak maintenance light both turn on

Both of these lights turn on when I start driving. I took it into an auto parts dealer and their scanner picked up no codes. There have also been a couple of times when the ABS light is triggered but I have had no issues braking. Seemed to be triggered at random then shut off. The low tire pressure light also stays on which is an error since the tires are all full. Not sure if that is related or not. I believe it to be a sensor issue, but I am not sure. Any help would be greatly appreciated.

More than likely this is a speed sensor issue. However, we should try a different scan tool because more than likely their tool could not pull the ABS codes from your vehicle.

Here is a video that will help with this:

Normally these lights are not on if they don't have codes, so we just need to double check.

The tire light is not going to be related to this and you are correct that this is most likely a tire sensor so let's get a new post started on that issue.

However, if we still find no codes then we should test the wheel speed sensors using this guide.

Once we have this info, we will be able to better determine the direction so let's start with this and go from there. Thanks
