Advance trac of lihts ist on

Christina, May just be a loose Tone ring, plug/wire,wheel speed sensor, etc. You will have to take vehicle into a good shop and have scanned for diagnostic codes to determine which sensor,wire,etc is bad and causing the advance track light to display and estimate repair. Check the attached links,instruction and guides, Good luck

AdvanceTrac Issues
Ford Explorer 4x4 with advance trac ABS trouble code C1235
2005 Ford Explorer Check Advance Trac Electrical Problem 2005

There are sensors for the ABS System & the Advance Trac
is an add on & sometimes any option, you have to order for that system

You just check your enhanced codes for that system & diagnose it like any other problem

Try disconnecting the negative cable for three minutes ! Or try you tube !

Advance Trac is an added feature of the ABS
Braking System, that could be purchased when the
car was built
It has nothing to do with the engine starting

You current issue is no different than any other
vehicle problem you have had since 1996 when
the OBD2 Systems came into being

You have a MIL Lamp on or check light as some people
call it

You should have checked fore codes immediately within a day
or so to at least know the codes & then googled them to get
some idea of the issues

You know that you have an ABS Braking System issue based on
your owners manual & your abiltiy to recognize Advance Trac etc

Have to have a shop diagnose that system with professional tools

With an AWD issue possible I wouldn't even use it until fixed

The trac control is ussually a bad wheel speed sensor or related
issue

The repair shop did not make the repair necessary

There are no advance trac sensors

Advance Trac is an add on option when new,
to the ABS Braking system

Even if the mil lamp is cleared, there will be codes
there when you access with a professional scanner,
since you have the amber lamp on

The only sensors are wheel speed sensors

well yo might need to change the bulbs they have a 2 tany wire one for the brake and one for the signal,so you might have them burned.

go to something like advanced auto, where they do free diagnostics tests they can sometimes reset trac lights and/or check engine lights but also if you where in to get an alignment they can also reset the trac light. but btw not every car has trac... if your trac is off it will not effect the proformance of your car.

I took my 2005 LS to the dealer for 40k maintenance stuff, oil and fluid changes, tire rotation, etc. The "check" Advance Trac light was an issue with me too. I would have figured that the Advance Trac system simply needed "checking" along with regular maintence because it was "time". However, this was a hold-over problem from the last maintenance I had had - the light had been coming on even after taking it to the dealer previously. I don't think the technician caught it the first time. This next time, I insisted that they look at it. It seems to have been a re-calibration was needed. Now it is fine again...
