JimmyKumbaya Posted October 1, 2018 Report Share Posted October 1, 2018 Good day, all. My 2011 Edge sometimes (say, every fourth or fifth time I crank it) generates a "Service AdvanceTrac" message (with the ABS and Traction Control idiot lights remaining lit after I dismiss the warning). The first time it happened, I used FORScan to look around and to clear the error (log file attached). The ABS/Traction Control indicators frequently spontaneously clear themselves during a short trip, and in any case everything 'feels' fine. In my ignorance I'm tempted to believe that means there's simply a loose connection somewhere, but I don't know where I should be looking. Any suggestions welcome.

enigma-2 Posted October 1, 2018 Report Share Posted October 1, 2018 How old is your battery? The FORScan log indicates below normal voltage. I would do a CCA reading. Can't trust doing just a voltage reading like the dealers do. I use (as do others here) a Solar BA7 to watch mine. accurate.

WWWPerfA_ZN0W Posted October 1, 2018 Report Share Posted October 1, 2018 Would still have the wheel speed sensors and tone rings checked to be sure. Quote Link to comment Share on other sites More sharing options...

The vehicle sat idle for a couple of months. After that, the first few trips yielded a message like "Charging System Problem" (or words to that effect), and a similar message when turning the engine off and removing the key. Since then there's been no (obvious) issue, other than perhaps a very slightly longer crank time. I'd pretty much put that out of my mind. Do you mention that based only on the log output, or do you have reason to believe a low battery could induce the AdvanceTrac warning? In any case, thanks for the reply. Jim EDIT: Oops, I didn't answer your question: the battery's a couple of years old. I'd be pleased if something that simple was the fix, as it's a little worrisome to my wife (while the fleetingness (?) of the issue makes it seem not so urgent to me).

enigma-2 Posted October 2, 2018 Report Share Posted October 2, 2018 Weak batteries can cause electrical problems like this. Back in the day you could count on a battery lasting 4 or 5 years. No so today. Once they have been fully discharged, they can be permanently weakened or destroyed (depending on the temperature). I would have it tested somewhere where they can tell you the CCA (cold cranking amps) remaining. I would also suspect it will fail. A weakened battery can cause all kinds of strange problems. 1 Quote Link to comment Share on other sites More sharing options...
akirby Posted October 2, 2018 Report Share Posted October 2, 2018 Do yourself a favor and just change the battery first. If nothing else you can rule that out and you'll have a fresh battery for the next 3 years. 1 Quote Link to comment Share on other sites More sharing options...
JimmyKumbaya Posted October 10, 2018 Author Report Share Posted October 10, 2018 Thanks for the replies. As soon as I've replaced the battery and driven the Edge around a while, I'll update my post. Jim 1 Quote Link to comment Share on other sites More sharing options...
Bfazona Posted October 21, 2018 Report Share Posted October 21, 2018 I just fought this battle myself. After checking everything, I found a chafed wire on the wheel speed sensor, which impacts both Advancetrac and ABS. Picked up a new sensor, swapped it out and fixed my problem. 1 Quote Link to comment Share on other sites More sharing options...
JimmyKumbaya Posted October 21, 2018 Author Report Share Posted October 21, 2018 (edited) Thanks for that feedback. Am I right that the speed sensors are partially hidden beneath plastic panels that are easily removed? I got the battery replaced (it was under warranty from Wal-Mart), the ride home didn't clear the AdvanceTrac warning but I'm going to give it a couple days before running FORScan on it again.

WWWPerfA_ZN0W Posted October 22, 2018 Report Share Posted October 22, 2018 No plastic panels to deal with. You have to remove the wheel/tire to get to each one tho. 1 Quote Link to comment Share on other sites More sharing options...
Bfazona Posted October 22, 2018 Report Share Posted October 22, 2018 Like WWWPerfA said, there are no panels to completely remove, although you do need to remove a few push pins for the inner fender. This will give you enough access to remove and unplug the wheel speed sensor, which runs toward the front of the vehicle. I would try cleaning yours, which only requires an 8mm socket to remove. Wipe them down and look over the wire real good. 1 Quote Link to comment Share on other sites More sharing options...
