Generally with car errors I adopt the PC approach, turn it off and on. If the error goes away file it away if it comes back later.
Imho the biggest problem with cars these days CANBUS it wasn’t really designed for dozens of modules loads of traffic it’s part of the reason for so many spurious errors you get randomly etc. It’s high time car designers got together and came up with a good solid standard with encrypted traffic, parity to ensure data integrity etc. That’d avoid the whole one module goes bad and wipes out the whole network
