SnowStorm Posted September 9, 2014 Report Share Posted September 9, 2014 Questions:Does any of this reprogramming have unexpected consequences - like removing Lifetime sceen or resetting accumulated values? Will it be covered under warrenty if car is past 36,000 miles when you have the first occurrence? Will it be covered under warrenty if car is past 36,000 miles and you did have a previous occurence? Will Ford do it as a "precaution" if you never had a dead battery?Page 5 item 3 is quite informative - I now understand the term "green thumb drive". It doesn't use any power!

Adrian_L Posted September 9, 2014 Report Share Posted September 9, 2014 Very interesting. It would appear that vehicles built after 6/3/2013 have had treatment to the wiring harness. Quote Link to comment Share on other sites More sharing options...
jdbob Posted September 9, 2014 Report Share Posted September 9, 2014 About what? All of the items that have been found to be causes of inability to start car that are not mentioned in this TSB? About thumb drives not drawing power. Actually, there should be no reason for a customer to remove anything plugged into a USB port. Those ports are powered by the APIM (Auxiliary Protocol Interface Module) which is what runs SYNC. When the car is powered off it should always shut down regardless of what might be plugged into a USB port. Quote Link to comment Share on other sites More sharing options...
salman Posted September 10, 2014 Report Share Posted September 10, 2014 Very interesting. It would appear that vehicles built after 6/3/2013 have had treatment to the wiring harness. Yes, to the wiring harness at the rear hatch, regarding a chaffing problem. I'm surprised this TSB is not about water intrusion in connectors under the front hood, since the SSM notice from early summer or late spring told service departments that a TSB would be out in 3rd quarter about the water intrusion problem.

SnowStorm Posted September 10, 2014 Report Share Posted September 10, 2014 3rd quarter? 3 weeks yet to go! The Enterprise (our car) was built in April 2013. Do TSBs show on ETIS site? Quote Link to comment Share on other sites More sharing options...

jdbob Posted September 10, 2014 Report Share Posted September 10, 2014 Not so. My USB thumb drive had an LED and it stayed active all the time. I unplugged it and my 12V battery SOC stabilized. What does the LED have to do with anything? All it does is make the thumb drive draw slightly more current when it is powered. The point I was making is that once the car is turned off the APIM should turn off in all cases - which will result in power being turned off to the USB sockets, regardless of what is plugged in. Apparently Ford hasn't figured out how to make the APIM shut off 100% of the time. Since it's running Microsoft Automotive OS maybe working 100% of the time is too much to expect.

IMO, it was able to keep the buss active and that made the APIM stay active.Why else would the SOC stop dropping after it was removed from the USB port ?

IMO, it was able to keep the buss active and that made the APIM stay active.Why else would the SOC stop dropping after it was removed from the USB port ? You have cause and effect reversed. The LED flashing just indicates that the APIM is reading from the thumb drive even though the APIM is supposed to have gone to sleep. The thumb drive can't tell the APIM to do anything, the APIM is in control. I had one instance where the APIM did not shut down. Opening the door (which starts a bunch of stuff up, including the APIM) and then closing the door again resulted in the APIM shutting down normally after 30 seconds or so. The APIM software works 99.9% of the time but sometimes it just doesn't do what it supposed to do. Quote Link to comment Share on other sites More sharing options...
JAZ Posted September 10, 2014 Report Share Posted September 10, 2014 Couple weeks ago after shutting and locking doors I stayed by the vehicle and noticed the instrument panel lights did not go off (probably more than a minute, and much longer than usual). I re-entered the car, started and stopped the ignition, exited and locked and that time all went well. But if I hadn't happened to check? SEL built early Feb. 2014. hybridbear 1 Quote Link to comment Share on other sites More sharing options...

If your theory were valid, the amperage draw would not havechanged as the APIM would have still been active and drawing amperage after the drive was removed.How do you explain the amperage draw turning off after removing the drive, if it wasn't the drive causing theAPIM to stay active ????????????

jdbob Posted September 11, 2014 Report Share Posted September 11, 2014 Did you open the door to remove the drive? That would be one explanation. Another is that when you removed the drive that causes different code to be executed in the APIM, at that point maybe it finally figured out it wasn't supposed to be on in the first place.

USB has two data pins and two power pins... the LEDs I've seen on thumb drives are powered by the power pins, regardless of the data - and then flash upon data usage. Not knowing anything about how it's actually set up... is it possible that the power pins are connected directly to the battery rather than switched via the APIM?

Not knowing anything about how it's actually set up... is it possible that the power pins are connected directly to the battery rather than switched via the APIM?Yes, It would be very possible. It's a draw and that's all I can report on. IDK if it was keeping the buss active or not, but othershave been pointing to that possibility. Either way, the draw stopped pulling my SOC below 75% after unplugging the drive.That's also the only thing I could verify with my charger. I never tested the parasitic load or verified what the draw was.Only that it stopped after removing the drive from the port..

BobJustBob Posted October 2, 2014 Report Share Posted October 2, 2014 Well, I got this TSB applied this past Tuesday, 30 September. I will be keeping my fingers crossed that it fixes the problem with the 12-volt battery going dead. Quote Link to comment Share on other sites More sharing options...
skibotoo Posted February 6, 2015 Report Share Posted February 6, 2015 About a month ago my MFT when unresponsive. I could touch the screen, but was unable to control the radio or other functions via the touch screen. The voice control button didn't work either. I performed a reset on the MFT, and still was unable to use the touchscreen or voice commands. I was planning on taking it into the dealer to get it looked at. Before I was able to schedule the visit with the dealer, my battery was dead after sitting for ~12 hours. We had nothing plugged into the USB or 110v ports. I got it jump started and the MFT and voice commands returned. I took it into the dealer a couple of weeks later and mentioned this incident, and they performed this TSB. All has been well now for a couple of days. Just providing another data point. Quote Link to comment Share on other sites More sharing options...
FredGreen Posted March 24, 2015 Report Share Posted March 24, 2015 Is there a way to tell whether my C-Max has had this performed without taking it to the dealer? Some way to see the IDS verison used to program these modules? Quote Link to comment Share on other sites More sharing options...
Dr.Ed Posted December 19, 2015 Report Share Posted December 19, 2015 I had the same problem. Energi built spring of 13.Was driving and had a glitch. Radio was playing but all touch screen and mechanical controls to radio were inop.couldnot use voice command, on-off button, volume updown on steering wheel, knob on dash. Got tomy destination, turned car off. Plugged into 120 charger. Radio would not shut off. Next day car was dead. 12 volt jump and everything back to normal. All controls work. Wondering what the glitch was that caused the MFT and all mechanical switches to stop operating. Quote Link to comment Share on other sites More sharing options...
