I have a 2011 GT base model. When i bought the car I could press the traction button once and immediately traction control would turn off. Then if i press and hold it, advancetrac would turn off. I press the button again and everything comes back on, just like the manual says. No problems
Now when i press the button nothing happens. I have to hold it for a few seconds and just traction control will turn off. If i press the button to turn traction on, nothing happens, even when holding it. Now when i press and hold the button I can't get advancetrac disabled.
Anyone have this happen to you? Maybe its just as simple as disconnecting the battery?
I think disconnecting the battery to reset the computer is worth a try; other than that I think it's probably a dealer diagnostic thing . . . sounds like the physical wiring is OK because it does respond, it just doesn't respond correctly
I hate to ask the obvious question, no offense, I just look for the simplest solutions first. You are holding the brake when trying to disable AdvanceTrak correct? I know you can disable traction control without holding the brake but not AdvanceTrak. Disconnecting the battery for 15 minutes would be a where I would start next, don’t forget to relearn your idle if you do. After that I would try removing the bezel to expose the switch and looking at the connections for corrosion and cleaning them. After that, if still not working properly, I’d hook up a multimeter and check the signal isn’t breaking up while keeping it depressed. Meaning something inside the switch itself wasn’t working properly, because we know it can send a momentary signal, it sounds to me that something is interrupting the signal to the ECM. Good Luck, hope this helps in some way.
good point, agreed, always check the simple and free stuff first . . . in my 2010 I'm pretty sure it works as below, assume the 2011 is the same:
> press button once with foot on brake, car can be moving -- traction control off (advance track on, normal mode)
> press button twice (fairly quickly) with foot on brake, car can be moving -- advance track sport mode
> hold button for about 10 seconds or so, foot on brake, car stopped -- advancetrack off
I see the OP hasn't been back for a while, not sure if he found the solution or lost interest . . .
