1) rear guidance lights are a BCM limitation. A 21+ bcm may fix this, however I haven't been able to get a dealer to commit to doing the programing. I'm not sure if a slave bcm with Jimmy's harness for the digital rear view mirror would help or not. Haven't tried that yet or asked?
2) try reading cvpm faults under diagnostics. Clear them if you have any, then try calibrating again. I ran into an issue recalibrating after a new lift and this solved it. Before the rear camera wouldn't take even after working previously.
So I just got some time this weekend to mess with this. Again this is on a 2019. The error I have been getting is
Failed. Condition not correct or request sequence error
I attempted to clear any outstanding errors. Only error that was present was
Faults reported:

Faults found.

When I go to clear it and having the surround view up, the few seconds the fault code stays clear it will actually show the correct spliced 360 picture and the guidance lines. Then shortly after it will go back to the white and black avoidance areas and blacked out 360 area.
I have a the Infotainment 2018+ FCA Security Gateway Module Bypass.
Looking to get XTOOL FCA 12+8 Cable Adapter for Chrysler SGW Bypass Cable Connector, as I already have an XTOOL
Looking for thoughts and/or suggestions.
Edit: With doing a manual code of 8502 x2 within the CVPM, then disconnecting, reconnecting immediately, then clearing any faults. AlphaOBD allowed me to start a calibration, see all guidelines, and the 360 view. However, it was dark and none of the calibration would take, and all end in a fail. I will try tomorrow during the day. So is this a bug within AlphaOBD?
