You will need AlfaOBD, the "Yellow adapter cable" to access the BCM module, and possibly a 5 digit manufacturer key code.What year is your van? Mine is a 2018, looks like I need some sort of adapter to bypass Something. Figured you did this already and would be able to walk me thru it.
I found someone to trade with before but since my airbag light came on I bailed and swapped back.
I'm willing to try on mine. I bought the OBDLink MX+ just need to figure out the software side of it.
My PM is 2015, not sure if the special 2018+ security stuff applies to PMs.
Should be most of the info you need in this AlfaOBD thread. Definitely some people with newer PMs using the app.
