No reverse lights or camera (goes back to the radio) when letting the clutch out while in reverse

Has anyone else experienced this and had it resolved?

My Ford dealer says they never heard of it before me, but has a suggested fix that the extended warranty company I have has approved with a caveat.

IF replacing the Body Control Module fixes the issue, they will cover all warranty costs.
If it doesn't fix the problem I'm on the hook for 280$ labour and 950$ for the unit, which a competitor dealer has in stock but is worldwide back ordered otherwise.

Side question. I have the DSC controller, please tell me that isn't the BCM.

Thanks!

When the reverse switch is engaged, pin 31 in connector C1926B at the PCM is grounded. Looks like the PCM communicates that over the CAN to the BCM that controls the reversing lamp relay you are likely hearing. But, I think the PCM also communicates that to the IPIM to activate the reverse camera on the dash. Because both the reverse lamps and the camera are affected, I would think the BCM is less likely the issue. I looked a bit deeper into the camera and there is also a LIN from the BCM to the rear camera, so it could be the BCM. But unless they have confirmed with their IDS that the PCM is still sending the data that reverse is active when the lamps go out and the camera turns off, I would not approve the BCM replacement.

My first thing would be to do the shifter cable reset procedure, just to make sure that it is not just barely engaging the reverse switch just slight enough that when the gears get loaded as power is transferred through the clutch it's moving something just enough to deactivating the reverse switch.

If the issue persists after the shift cable reset, test that the previously mentioned pin at the PCM is staying grounded while backing up.

If not, I would put a test jumper in where the reversing switch is, if the problem persists, it's in the wiring or the PCM. If it works with the jumper though, likely need a new reversing switch.

Do you mean that it goes back to radio when you fully release the clutch and rear is engaged?

For me the camera keeps operating even after I'm in neutral and even in first up to maybe 3-5 MPH going forward. I also have a DSC controller and it has had no effect on the reverse camera behavior but since they both use the CAN bus, it's possible if one goes bad to have an effect on others.

The camera remaining on is a delay setting in the sync3 settings you can toggle on or off.
