Advanced Track

So question, every so often(mainly in winter) when I start my car my Advanced Trac button tell me to check it, but then when I restart my car it doesnt happen again, whats causing this?

You have a intermittent fault somewhere. The two most popular causes are: (1) steering wheel angle sensor or (2) YAW sensor.

Mine did that a couple of times during the winter, soon as I backed out of the driveway it went away, hasn't done it since winter, I just chalked it up as some slush/condensation getting into places it shouldn't. who knows? I don't fix things that go away by themselves. If the problem returns and does it again and stays permanently I'd look into it. Like Joe says, a sensor somewhere, wouldn't surprise me if it's not liking the wet weather. No need to panic yet.

Mine occasionally does it, but only seems to be when it's wet out so I am thinking along the same lines as BigRig.

Joe, other than the TC sensors at the wheels, is there another sensor exposed to the elements that could have a failing waterproofing/seal down under the car somewhere?

The yaw and steering sensor are all in the vehicle.

Might be inside the vehicle but it happens when it's cold and wet out, now mind ya, mine stopped doing it and it was only a handful of times throughout the winter. If I recall correctly I was also getting a Check E-brake notice or ABS, I do believe it was that, might be off ... two errors on starting the LS, turning it off and restarting always made it go away. Just putting it in reverse and backing out made it go away as well. It was mostly during the extreme cold snaps.

I could care less, it went away, I have one of those self correcting models it would seem. If it acts up again, I'll trace it down but something tells me something underneath is not liking the wet/damp conditions throughout the winters. It's not doing it in the rain, so it's related to cold temps, something freezing up, dampness shorting something related to the wheels.

Generally, the YAW sensor and steering wheel angle sensor should be the only ones that can trip the AdvanceTrac light and not trip the ABS light. An exception might be some sort of CAN bus fault.
When you first start the car, conditions inside are not too far from the conditions outside. Anyway, you need to scan tool that can pull the ABS and other codes to figure it out.

Came on again today while accelerating uphill, wet but not raining at the time.

Just going to have to get a scanner or find someone with one. Any recommendations on scanners?

I have check advancetrac on 03 Navigator all the time. I just bought the truck the seller said it was caused by the new coil overs (airbag swap). Does this make sense to anyone here?
I know this is the LS thread but i seen the topic, thanks for the help

short answer is yes, it is possible to mess something up while switching from air shocks to a coil setup.

long answer is to have it scanned and see what the actual problem is and go from there...
