HELP. Front Camera Fault, Codes: U0422 & B115E

[glassutk1]

Hey guys,
I've got a couple of faults causing my front camera system to be offline, which is also disabling my lane centering capability and my blue cruise.

• PCM - U0422:00-2F
  • Invalid data received from the body control module
• BdyCM - B115E:08-0A
  • Camera Module
  • Additional fault symptom: Bus Signal/Message Failures

This camera issue recently began when I tried to run some service procedures to calibrate cruise control, headlamps, and lane departure system, after leveling the truck and thinking that new calibrations would benefit the systems. In hindsight, I should have left them alone because they were all working correctly.

As part of the troubleshooting process, it was determined that one of the level sensors was bad, keeping the Headlamp system from calibrating initially. However, this has been corrected and the HCM has been recalibrated.

Now it appears that the remaining issue is contained within the BCM.

To note: the cameras are actually working and sending some pathway signals, because when parking or manually pressing the camera button, the 360 view works correctly, the front bumper view works correctly, etc. However, for some reason, the PCM doesn't seem to be reading the BCM or ?

To note: I also have backup files from months ago, when all systems were working just fine, before any FORScan adjustments were made, so perhaps the answer to my trouble is to just roll everything back. I'm not positive about this move because the truck has recently taken some OTA updates and I don't know if the older version back files will mesh with the newer updates within other modules?

I would appreciate any input from more experienced dudes. Let me know if you need more info.
TIA!
Andrew

Did you ever resolve this?

Looks like 2 problems:
1. PCM - did you attempt to change tire size? If so, the PCM has a hard-coded limit which has been exceeded in the setting of tire circumference in the BCM.
2. BCM - it seems to be complaining about the CMR module which is the nanny-cam looking at your eyes for bluecruise. Has anything been done to disconnect or deactivate the CMR module?

Just FYI, the windshield camera is used for lane centering and adaptive cruise; it uses the front emblem camera for the 360 view.

Just didn't want you to think that the windshield camera was fine if your 360 worked.
