No RVC, 360 Camera, or heated/cooled seats after upgrade from sync 2 to 3

Ford SYNC 3 Support

I tried this but it still didn’t work. I get the same black screen with the plus button, truck in the upper right for parking sensors and text on the bottom saying “Please check surroundings for safety”.

Tried LIN calibration and camera calibration and they both keep stopping at 8%. Any idea why that would be happening?

The camera is actually bad. Or there is a connection issue.

Have you removed the tailgate? There is a connector under the bed in the back that gets water and corrosion in it that you might want to check.

Did you make the APIM corrections?

34

Made the APIM corrections and did the master reset. I’ve never taken the tailgate off, but I did disconnect and reconnect the connector yesterday thinking maybe that had something to do with it. I hope it’s not the camera that went bad.

I may try to swap the Sync 2 module back in this weekend to see if it still works under that. I’m not eclectically inclined enough to check wiring/connectors to see if the camera is getting power, etc.

Did you get a resolution to the issue?
If not, did you run the IPMB Local Interconnect Network New Module Calibration?

I did some research on the rear camera issues and found some info that may help. In the BCM, the setting at 726-39-02 xxxx x*xx xxxx is for the rear camera ‘slave’ operation. You now have a Sync 3 APIM which means your camera is not a slave RVC. Your camera is driven by the APIM now. 2011 thru 2015 vehicles with a 4.2" display had an FCDIM instead which is when the slave RVC setting would apply. Also, CGEA 1.2 vehicles use this setting with Sync 2, and some CGEA 1.3 vehicles I have found this setting active, some not. If active, it causes issues with Sync 3 upgrades.

Follow this:

  1. Connect FORScan and go to the BCM (Body Control Module) Asbuilt Configuration.
  2. Save the BCM configuration asbuilt before you make any changes. Always do this immediately when you enter any module as a habit.
  3. Locate 726-39-02.
  4. Looking at your factory asbuilt file, attached here, your setting for this line is:
    726-39-02 0101 0101 006C
    Change the line to:
    726-39-02 0101 0001 006B (If the checksum of 6B is incorrect, let FORScan recalculate it.)
  5. Write the change to the BCM.
    NOTE: The BCM is going to reset and cause all sorts of mayhem. This is normal, don’t worry about it.
  6. Once the commotion is finished, save the new BCM configuration, and exit the BCM (Body Control Module) Asbuilt Configuration.
  7. Scan the vehicle for DTC’s, there will be a few most likely. Clear all the DTC’s.
  8. Go to the Tools tab (wrench) in FORScan and run the BCM (BdyCM) Local Interconnect Network New Module procedure. Follow the instructions.
  9. Once this is done, you might need to drive the vehicle a bit for the system to start working, but it might work as soon as you put it in reverse with the vehicle running.

Let me know if this works for you. Here is your factory asbuilt file. Keep in a safe place.

@McF150
Were you able to make any progress on the issue?

Hi. Sorry I meant to say thank you for digging into this more, I really appreciate it as this has me completely stumped. I followed your steps exactly, but still cannot get a LIN procedure to go beyond 8%.

I haven’t had a chance to pull the unit out and see if the camera still works under the Sync 2 setup. Still getting the same black screen but everything else is showing up (plus sign, truck in upper right, text, but no guidelines).

I’m wondering now if it’s the APIM itself or some connection that’s not right on the back end.

What adaptor are you using?

40

I just reconnected the factory harness that connected to Sync 2 when I put in the Sync 3 module. No adapter.

41

Sorry, I meant the ODBII adapter.

It really looks like the camera is either bad or there is a connection issue. The LIN procedure does not appear to be able to connect to the camera.

44

Just to let everyone know, the company I bought the kit from sent me a new APIM module which solved the problem. I guess the module was just bad.

It happens. At least they provided you the proper support and fixed the issue. Thanks for the feedback.

46

A similar situation happened for me. The vendor sent me a new unit and it now works (I confirmed the camera worked under Sync 2 as well). Now my issue is that I don’t have the steering guidelines (white curved lines) or zoom functions. Any thoughts as to how to re-engage those functions?

47

Was it the same vendor?

Thanks again. Mine was a vendor from China through Amazon. @Bparma3 who was your vendor?

I was finally able to get my moving gridlines and zoom functions back by reversing the change in the BCM back to 726-39-02 0101 0101 006C from 0101 0001 006C. I still can’t run a LIN or a Rear Camera Calibration but it all appears to be working fine so far (i.e. lines turn the the steering wheel and zoom in on camera works over hitch). Thanks all for you help on this!
