Not the OBD app you’re looking for

Requires expensive subscription and proprietary reader.

Reasons

The process is very slow and doesn’t load properly all the time when using the app and switching to wiring diagrams need something that allows users to actually read what we are clicking on when using workshop I feel like it’s something to do with the format but some improvements can be made for sure. It’s very hard to follow a pinpoint test or even get to them through pc/ed
