mobrien118 Posted April 20, 2016 Report Share Posted April 20, 2016 Hello, I had my 2011 Edge in to the dealership 2 weeks ago to perform the work described in "Bulletin 13N02" - ("Extended Warranty on Brake Booster on Ford Edge"), due to moderately severe issues with the brake pedal caused by a torn brake booster. I got it back from them and the next day the "Service AdvanceTrac" warning came up on the instrument cluster. It only happens when the vehicle is idling for a bit. I called the dealership back to report what was going on and they said "It is probably just a coincidence" and "We will take a look at it for $199, which will be applied to any repair." Seriously? A new warning *related to the brake system* comes on the day after you complete work on the brakes, and you suggest that it is a coincidence...? Anyway, does anyone know what the common causes of this issue are? Especially ones that could be caused by replacing the brake booster... Thank you *very* much! --mobrien118 Quote Link to comment Share on other sites More sharing options...
macbwt Posted April 20, 2016 Report Share Posted April 20, 2016 Might be a bad connector for the wiring. Only a diagnosis will find it along with a wiring test to isolate the bad connector. Could be other things also, but diagnosis is about the only way to identify the problem Quote Link to comment Share on other sites More sharing options...
mobrien118 Posted April 25, 2016 Author Report Share Posted April 25, 2016 Right, I'm trying to use the power of forum groups to aid in the diagnosis, which I will perform for less than $199 myself. What I'm looking for is: what common causes of AdvanceTrac failure coincide with recently having work done on your brake system; Specifically, issues that would cause a warning to be displayed when the car is warmed up and only when recently parked. I am hoping that some other people have had similar issues with the system and can point me in the right direction before I go digging. Unfortunately, as experienced of a "weekend warrior" I am, I have very little knowledge of how the AdvanceTrac system works. Thanks, --mobrien118 Quote Link to comment Share on other sites More sharing options...
Waldo Posted April 25, 2016 Report Share Posted April 25, 2016 If you can just read the code, the car will tell you exactly what the problem is. Quote Link to comment Share on other sites More sharing options...
PaulSchott Posted April 25, 2016 Report Share Posted April 25, 2016 After a brake booster repair, the brakes are bead to remove air from the lines. When doing this there is a chance they broke or disconnected one of the wheel sensors. These detect wheel rotation and activate the traction control. This system will self diagnose a malfunction and give you a warning light if something is not right. Quote Link to comment Share on other sites More sharing options...
mobrien118 Posted April 26, 2016 Author Report Share Posted April 26, 2016 I have a bluetooth OBD-II scanner, but the code doesn't show up on the main register (at least not after it is not displayed, I haven't been able to catch it in the act, since this is my wife's car). It seems that the code is clearing out after the issue is cleared. I remember back in the old days, before ODB-II there used to be multiple ports as different systems had separate computers. That wouldn't be the case here, would it? Thanks!! --mobrien118 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted April 27, 2016 Report Share Posted April 27, 2016 Only one port to read/access data from on these OBDII systems, if that's what you are asking. You can "interrogate" components separately of course, with the right hardware/software, I am sure. Quote Link to comment Share on other sites More sharing options...
