Hi all- I recently upgraded my 2015 F-150 supercab lariat from sync 2 to sync 3. I removed the original sync 2 module (non-nav) with a sync 3 module (with nav part number kj7t-14g370-acd). the removal and install & upgrade went smooth and i also upgraded to sync 3.4 as well as the latest maps update with no issues. Everything powers up and works perfect except 2 issues: The 1st issue i have is the navigation is “wandering” after i drive about a mile or two, the navigation shows me about 5-10 miles from where i actually am. I thought the issue was from the aftermarket antenna, so i replaced the oem roof antenna with the updaded one (HL3Z10E893AA) & installed the splitter harness (GL3Z10E928AA) as recommended on this forum. both of those did not fix my issue as it strill “wanders around”. The 2nd issue i am having is when plugging in to forscan, i am showing a “U2101 control module configuration incompatible” code. the radio functions perfect with everything working as it should and no other issues besides the gps wandering. I can reset the code but keeps coming back. no other modules have codes present. when installing sync 3, i thought i had loaded the correct as built data into the apim, but i am at a loss right now. i can provide the original asbuilt data as well as the current. PLEASE HELP, i would GREATLY appreciate it!!!
SYNC Region: NA
Navigation Variant: Nav
Manufacturer Year: Pre MY20
Install Type: Retrofit
Old SYNC Version: 2.2
New SYNC Version: 3.4.23188
Do you have a error message, if so what is it?
APIM U2101
Please run the Interrogator Utility and post the xml here. Also look for the DTC’s and list them. The U2101 code is for an invalid configuration of the module.
I just loaded the data into the apim module and performed a reset. At first i was having the same issue with the gps from before, but after driving it a few miles (same test route as last time for accuracy) all of a sudden it got super accurate and never lost direction again. i even drove the same route a 2nd time just to be sure and no issues. I also scanned the modules again and no codes found in the apim!! Thats awesome news. Im not sure if the modules require certain amount of key cycles to re-trigger a code or not, so ill drive it and cycle the ignition a few more times and then re-scan, but im very confident that the problem is fixed after seeing the new data you sent me. Its crazy how a few numbers can really change the operation of the module..I even noticed that after entering the new data, the radio seems WAY faster and snappy. I REALLY appreciate the help, you have no idea how much it means to me to get these issues resolved. if something comes back up ill post another message, but for right now i think its fixed.. now just have to figure out my TPMS issues and why the new sensors wont pair to the truck.. THANKS AGAIN!!!
Thanks for the info. Glad I could help.
Which sensors did you ourchase and install? I just had to do this earlier in the year…
Do you have a TPMS training tool?
I just bought a set of aftermarket fuel wheels & tires from custom offsets… I bought the oem motorcraft sensors and had my buddy who has a tire machine install them and balance the wheels. He tried pairing the sensors to the truck with his snap on scanner but they wouldnt take the pair. However the tool shows the serial number and battery percentage of each sensor which is weird. We tried pairing using the ignition cycle method, pressing the flasher 3 times method, and also the forscan method which none worked. Im at a complete loss, because if we go into pair mode then install the oem wheels they detect the sensors no problem. I double checked to make sure i got the correct 315mhz sensors but after doing some extent research 2015 models had major issues with pairing new sensors. So ill probably take it to either discount tire or the dealer in the next few weeks. One of those things where its not a 911 repair but watching the light constantly flash in the dash is annoying.
Well, the right sensors pair right up. There are a lot of knockoff sensors that are really iffy about pairing. I know about the flashing light, it is annoying.
The reports of sensors not pairing boils down to aftermarket sensors. However, there are some that work for not a lot of cost. Unfortunately, if the tires are mounted it’s a pain to get them replaced.
I used these, no issues at all. Paired up fine with the Snap-On tools unit.
If you take it to Discount Tire they will they to sell you their sensors at about $60 each. You should just go to your Ford service center rather than them.
I got the motorcraft sensors on ebay so i hope i didnt get scammed.. we bought 4 sensors earlier this year from the same seller and installed them in our 17 explorer with no issues, but the f150 wont pair.. ill take it to the ford dealer hopefully this week yet. They have been servicing both of our vehicles since new and are very good to us, so maybe i can get some info from them. If all else fails ill get the sensors that you recommend and have my buddy switch them out. Thanks again for the info, i appreciate it!
Sorry to bring up this thread again.. i finally got the tpms sensors replaced and fixed… all good..but when clearing out the code using forscan i noticed i now have a code in the FCIM. It says: U0452:82-08 invalid data received from the restraints control module. Is this related from the apim changes? Or is this a separate issue? I was doing some research on this code and theres not alot out there. I was able to find ford tsb #46902 on this but wanted to check first about the apim. Other than that fcim code i dont have anything else. Thanks again!
It seems this is a common code seen in the F-series trucks. Usually it is of no concern as it is just invalid or malformed data. In this case to the FCIM, it is likely the status of the belts and/or airbag fed to the lighted icons in the FCIM. This does not mean the OCS and safety systems are not working, just that there may be a network issue like congestion that may have blocked or interrupted the CANBUS traffic. If the error is persistent and happens all the time, it would be a cause of concern. But by that time you would probably see the IPC warning and issues with other modules. Keep in mind that the SRS system is self contained and does not rely on other modules to function.
The document you reference is an SSM, not TSB, which is an advisory message. It is attached here. MC-10127407-9999.pdf (6.1 KB)
As stated in the document, you could perform an FCIM self test. Your FCIM will likely pass if all you controls are working.
Thank you for the information and clearing it up, i do appreciate it! I will perform the test and keep an eye on it but sounds like if its a common issue, then i wont worry about it. Thanks again!
