chefduane Posted August 29, 2017 Report Share Posted August 29, 2017 Ok so I don't know what is going on.... the particlulars: 2011 AWD Limited, 75k miles, brake booster retro done at dealer 2 mos ago.. no other issues. Got in and started the car this morning and received a "Sync Update" message on the center screen. Ok, no problem, happy that Sync is being updated. All was well until the next shutdown and startup. Upon the second startup I got an "Advance Trac Warning" indicator on the left info screen. Simultaneous with that was the "ABS" indicator, the traction control indicator (the little vehicle with the squiggly lines underneath), and the traction control indicator (same as the one previous mentioned) with "OFF" underneath it. I cleared the "Adv Trac" warning but the other indicators have stayed on. The "Adv Trac" warning came on again after another shutdown and startup. The manual makes no mention of possible issues other than to inform the reader to 'have the system checked at a dealer' if those warning appear. I have checked the underhood fuses and all are ok - #5 ABS Pump, #43 ABS Valves, and #92 ABS Module. There are no fuses/relays listed that make mention of the 'Traction Control' or 'Advance Trac' systems. I tried to pull codes with my OBDII scanner and there are no codes. None. I even "Cleared All Codes" just to make sure and I still get the warning indicators. I don't know if the Sync Update has anything to do with the warnings appearing, maybe its just a coincidence. Before I take it in to the dealer and bend over, does anyone have any suggestions or feedback on any other diagnostics that I can do? Any suggestions would be appreciated. Thanks!!!

Gbczyk84 Posted August 29, 2017 Report Share Posted August 29, 2017 A weak battery could be the problem, I'd start there if it hasn't been replaced. 1 Quote Link to comment Share on other sites More sharing options...
chefduane Posted August 29, 2017 Author Report Share Posted August 29, 2017 Replaced the battery in June with a BXT-65-850 AGM so I'm thinking its not that. I did read something about disconnecting the battery and then reconnecting. Have not done that as yet. I also came across TSB 13-1-15 that concerns exactly what my symptoms are. Requires a PCM update to IDS Release 83.01 or higher. If I do have to take to a dealer shop perhaps that might clear the issue. Anyone have an idea how much a PCM reflash co$t$? I am out of warranty. 1 Quote Link to comment Share on other sites More sharing options...
macbwt Posted August 30, 2017 Report Share Posted August 30, 2017 (edited) The MAF will cause a Traction Control and advance track warning. Is it clean, is the MAF plugged in and is your air filter clean? and if you are using a KN filter then the MAF may need cleaning.

chefduane Posted August 30, 2017 Author Report Share Posted August 30, 2017 I have the same setup as you, Mac. AEM Dryflo filter - no K&N, no oiled filter. I don't think it could be the MAF as I cleaned it when I purchased the vehicle at 65k miles. I'll check it tomorrow but I assume it is plugged in and functioning. Follow up question: Do you think it would be OK to drive it in this condition? Nothing seems amiss and it drives fine. I need to use it for a day or so until I can get it to the dealer but I don't want to risk any damage. 1 Quote Link to comment Share on other sites More sharing options...
omar302 Posted August 30, 2017 Report Share Posted August 30, 2017 I'd also suggest the battery, even if replaced recently it could have a defect or the corrosion on the terminals or loose connectors. Disconnect the battery for 10 minutes and see if it helps. Also, you should use ForScan (with a compatible adapter) as it will also show trouble codes from all/most other modules, unlike a regular scanner that only scans for PCM codes (check engine light). 1 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted August 30, 2017 Report Share Posted August 30, 2017 Recalibration sounds a viable option. If you have a Solar BA7, you can check battery condition yourself. Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted August 30, 2017 Report Share Posted August 30, 2017 Anyone have an idea how much a PCM reflash co$t$? I am out of warranty. My guess is 1/2 hr. 1 Quote Link to comment Share on other sites More sharing options...
chefduane Posted August 30, 2017 Author Report Share Posted August 30, 2017 (edited) I may try the battery disconnect test first just to see if that clears anything. In Re; low battery. I've already replaced the battery 2 months ago and when *that* battery was going out I got a "Low Charging" warning and no "Advance Trac" warning. If *this* battery was loosing charge would I not see a similar warning ie "Low Charge"? Also, can I not check the battery with a simple VOM? What is a BA7 going to tell me that a VOM won't?

WWWPerfA_ZN0W Posted August 30, 2017 Report Share Posted August 30, 2017 A VOM is not going to tell you cold cranking amps. Voltage is just the front door. The CCAs are the house you are looking at. Plus it can check your charging system as well if you so desire. Quote Link to comment Share on other sites More sharing options...
akirby Posted August 30, 2017 Report Share Posted August 30, 2017 Ditto on the Solar BA7. And a C-Tek charger/reconditioner. You could also have a bad wheel speed sensor, broken tone ring or wiring chafe. 1 Quote Link to comment Share on other sites More sharing options...
chefduane Posted August 30, 2017 Author Report Share Posted August 30, 2017 Any feedback on if it is ok to drive in this condition? I'm thinking yes, albeit the ABS and traction control is non-functional. I figure I'll just take it easy for a day or two 'till I can get it to the dealer.

enigma-2 Posted August 30, 2017 Report Share Posted August 30, 2017 Triple on the BA-7. I bought one and my old battery tested low on CCA's. Read battery bad. I had two tests run on this battery by the local Ford garage; both times reported battery was fine. It died at the grocery store. Great little tester to monitor battery condition and charging systems. 2 Quote Link to comment Share on other sites More sharing options...
akirby Posted August 30, 2017 Report Share Posted August 30, 2017 It's fine to drive. If it wasn't the CEL would be blinking. 3 Quote Link to comment Share on other sites More sharing options...
chefduane Posted August 30, 2017 Author Report Share Posted August 30, 2017 Thanks AK. I just needed some assurance (second opinion). Prolly drop it at the dealer on Friday or Monday. Still off until end of Sept with knee rehab. Quote Link to comment Share on other sites More sharing options...
chefduane Posted September 6, 2017 Author Report Share Posted September 6, 2017 Dropped the Edge off at the dealer today to diagnose above listed problems. I also p[roved a copy of the PCM flash TSB and he service rep seemed to know about it and was familiar with the issue. Hopefully that it all it is but we'll see. $135 'diagnostic' charge so I'm into it for that already. 1 Quote Link to comment Share on other sites More sharing options...
chefduane Posted September 6, 2017 Author Report Share Posted September 6, 2017 Got the Edge back this aft (that was quick!). From the Invoice "DTC U3000:41 present. Performed PMI on RCM and ABS Modules. Performed IVD Sequence and cleared codes. Test drive OK, Retest OK, Battery OK." Now, I don't know what all that means but everything seems to be back to normal now other than my wallet being $270.00 lighter. 1 Quote Link to comment Share on other sites More sharing options...
