2007 Avalanche Stability Track and Engine Light

Lately, when we have wet weather, I get indication that stability track is off and to check traction control. However when weather is dry the indicator light goes out. But after two cycles of on and off, yesterday the indicator lights are off, but the check engine light is now on. Checking the code P0307, tells me that cylinder #7 has misfired. Are their any connection between the two issues, and how serious is the misfiring of #7 cylinder?

SOURCE: the service stability light is on

It pertains to just what it says STABILITY. Your vehicle has a system that will sense if you are coming around a curve at about 90 MPH. It will automatically apply a light amount of braking to the proper wheels, thus hopefully eliminating you and your Uplander from flying off curve. With the light on as with any warning light , you must assume whether its real or not, that the STABILITY system IS NOT operating. Significant computer / sensor diagnosis will be necessary. Hope this helps

SOURCE: error stability track and error stability control

I own a 2005 Avalanche. Had the same problem. Turns out there is a computer module which controls the Stability control and braking system. It is located under the drivers seat outside cockpit and is exposed to the elements. The computer is about $600 and requires about 2 hours labour. It then has to programmed by a GM dealer to match your vehicle.(another $150) Good Luck.Hope this helps.

SOURCE: I bought an used equinox

This just happend to me in my 07 Equinox, and they told me it was the throttle body sensor going out, and need to replace the entire throttle body which for some reason isnt covered by even the extended warrenty. Your looking at about $700 bucks to fix if it that on yours also.

SOURCE: My stability system and traction

Hello Tip.

All three systems rely on some of the same sensors in order to operate.
In this case most likely is wheel speed sensors. By far the most common problem.
The system will need to be scanned to find out which is the offending one and be repaired.
Not all scan tools have the capability to read ABS systems. Make sure whoever you take it to has this available. Most good shops will have this.
If you have further questions on this, please ask me here, be glad to help.
Thank you for using FixYa.

The flashing light DLC can mean a severe misfire making it run bad and possibly destroy the catalytic converter . Can you have the codes scanned and post them here ?

You can't. Some vehicles can turn off traction control, but not the stability traction.

Stability track

This is a common problem with GM's. The TPS sensor goes bad in the throttle body. Throws out a message to service Stabilitrac. Not SO!!!
The kicker is that the whole throttle body has to be replaced because the TPS sensor is actually part of the throttle body!!! Costs around $250.00 for aftermarket.

Stability track and traction control on dic information how to reset

Reset it?

You had that System Diagnosed & Repaired,
and the light is still on?

You do have some understanding of any lights you
get on the dash,your not just reading what other people
read & repeat in their questions?

Have you checked for codes,if this is a new problem,
and what are they.

I wouldn't be using it, until i knew what the issues were,
your braking system is involved there
