Front Park Assist AEV Bumper

[JW2024]

I have a 2024 2500 AT4X non-AEV edition that I just swapped out the front and rear bumpers for the AEV bumpers. The front bumper came plug and play. All sensors and fog lights installed with just 1 harness to plug into the truck. Since installing, my Front Park Assist has been hit and miss. It turns off on its own quite frequently and other times it says to clean the sensor. No issues with the fog lights. 
 

Any suggestions with how to fix?  The rear bumper works perfect.

Anyone here with the AEV edition truck that installed the winch mounting kit and front license plate bracket?  If so, any problems with your front park assist turning off?

Taking a stab in the dark but it could be a calibration issue.  If, and I mean if GM has two calibration files for ZR2/AT4X with and without AEV, they "could" have a calibration for AEV optioned trucks to work with the bumpers.

Ok. Thank you. I call the service advisor to see what he can find out.

Using SPS I can see the software versions in the K182 park assist module. There are 4 modules inside the unit with different software for each. I pulled the info from my truck, a 2024 non-AEV AT4X, and compared to a 2024 and 2025 AT4X AEV. Three of the modules share the same software number but the two AEV editions share a common 4th software version that is different from my non-AEV version. I’ll have to see if I can program that version to mine.
