I just successfully calibrated my CVPM after upgrading from UC4 to UC5 in my 2019. I had to get a 22+ CVPM to play nicely with the UC5 so I bought a new one and had to calibrate it via AlfaOBD. All of the info in this thread, plus a couple of assists from Jimmy07 and I finally got it done after 2 days. A couple of pointers (most of this is already elsewhere in this thread) that helped me out:
- The front camera was the hardest for me to get calibrated. I was able to get it done on the road in front of my house, which is unmarked (just a residential street in a neighborhood so no center line and no side lines). When doing the front camera, go as slow as the test will allow (basically idle at 2-3 mph). Make sure you're rolling
before start the test. Also shadows seem to affect it, so try and do it in a clear area with uniform light.
- The right, left, and rear cameras seem to do better in a parking lot with lines/stripes on the road. I tried endlessly yesterday to get these cameras calibrated on my street but gave up after about an hour of trying. Today I went to a parking lot that had both a center line and parking spots (see image) and the right, left, and rear cameras all calibrated first try. For the right and left cameras, I used the center line to calibrate those, and for the rear I straddled the center line. I couldn't get the front camera to calibrate here because there were a lot of shadows. I noticed every single time I went from a shaded area into a sunny area the test would fail.
- I'm 99% sure the CVPM will hold successful calibrations until/unless you run another calibration on that camera. This morning I calibrated the right/left/rear cameras first then drove home and calibrated the front on my street.
In AflaOBD (android version) my procedure was: connect to the CVPM, read faults, clear faults, disconnect, reconnect, read faults, clear faults, then run the calibration on each camera individually. SGW bypass was in the truck. The slower the better, the front did 2-3 mph and the sides/rear I kept it at or below 5 mph.
Side note: if anyone is looking to add the surround view to their UC4 system, I have the stock CVPM from my truck (P/N 68318033AG) available for sale, already calibrated!
