I have something for you to try for getting the dynamic lines working on the rear camera. This is for 2016 thru 2020 Explorers which are CGEA 1.3, as yours. It seems the adjustment must be made in the BCM since you upgraded from Sync 2 to Sync 3 for the rear camera functionality other than video.
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 should be 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.
Follow this:
- Connect FORScan and go to the BCM (Body Control Module) Asbuilt Configuration.
- Save the BCM configuration asbuilt before you make any changes. Always do this immediately when you enter any module as a habit.
- Locate 726-39-02.
- Looking at your factory asbuilt file, attached here, your setting for this line is:
726-39-02 0000 0101 006A
Change the line to:
726-39-02 0000 0001 0069 (If the checksum of 69 is incorrect, let FORScan recalculate it.) - 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. - Once the commotion is finished, save the new BCM configuration, and exit the BCM (Body Control Module) Asbuilt Configuration.
- Scan the vehicle for DTC’s, there will be a few most likely. Clear all the DTC’s.
- Go to the Tools tab (wrench) in FORScan and run the BCM Local Interconnect Network New Module procedure. Follow the instructions.
- 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.
