F150 - Does APIM Upgrade Impact BCM LIN?

Ford Non SYNC 3 Support

Hoping some of the smart people here can help with a question.

My 2015 F150 is unable to complete LIN New Module Calibration or Rear Camera Calibration in the BCM. They both get to 8%, ask to cycle the ignition, then I get “Test Aborted. Perform a self-test to identify any diagnostic trouble codes (DTCs)”. The BCM passes self-test with no codes.

Question: Does a retrofitted SYNC 3 APIM have anything to do with this issue?

More details… this all started when I bough a Ford OEM backup camera to replace my original. The replacement has a great picture but no backup guidance lines (the ones that move with the steering wheel). A LIN new module calibration may fix this issue but will not complete. So I took the new camera out, installed the original, and it still can’t complete. Pulled the battery overnight and no change. So now I am wondering if the APIM could have a role. In terms of mods, I have done minor Forscan programming, upgraded the APIM to SYNC 3, and installed OEM adaptive cruise control.

Is there any way I find more details on what is causing the BCM to fail calibration?

This thread looks similar but never got to the bottom of what is causing the BCM calibrations to fail at 8%: No RVC, 360 Camera, or heated/cooled seats after upgrade from sync 2 to 3 - #47 by F150Chief

What Forscan version are you using?

Do you have the 360 View option? Trim levels have this option and need to have the IPMB LIN cal performed. If your asbuilt is wrong for this it could cause this issue.

A retrofit from Sync 2 to 3 alone would not cause this directly unless the asbuilt is wrong. Does a camera self test complete?

2.3.71 with the OBD Link Ex.

No 360 view, just the single rear camera. I do not see an option to self test the camera but it works great, including guided backup lines.

how much was your camera? and were did you buy it?

I am not using the replacement camera at the moment - the original is installed with a 2015 manufacture date. The replacement is Ford and probably not correct but that is another issue.

8

yes but how much was it?

That is another rabbit hole. I paid ~$150 for a Ford FL3T-19H222-AH. It had a great picture but is not the correct part number for a 2015. I need to buy the $400 correct part number but do not want to do that if I will be unable to calibrate the reverse lines via LIN new module leaning.

Yep, an OEM rear camera usually goes for around $500. If you paid significantly less than that on Amazon or eBay and it was advertised as OEM, there’s a good chance it isn’t. That’s usually why people have trouble configuring them correctly.

Trust me, I’ve been through the same thing. What I ended up doing was going to a junkyard and pulling one from a wrecked F-150. I tested it on the spot and paid only $50 for it. The 2015–2017 F-150s use the same rear camera.

When you have a genuine OEM camera, everything typically works as soon as you connect it. You shouldn’t need FORScan to get it working.

I ended up swapping my 2015 camera and tailgate handle for one from an 18+. 2018 cameras are significantly cheaper and much better quality than my original 2015. Camera works as normal, but I did have to modify the handle slightly to get it to fit due to a difference in tailgates.

12

That is an interesting idea. Does the 18+ camera show moving guidelines when you reverse and turn the wheel? I would assume not, which is essentially the same outcome as me replacing the current camera with non-OEM or in my case, the wrong OEM part number.

Yes, the dynamic guidelines work as normal after I did the Rear View Camera calibration.
