  • 0088 fault w/JB4 installed on C43

    Not new to JB4, however lol.

    Installed JB4 on my 2018 C43 AMG. Only installed the two connections (left fp alone). The second I start it, CEL. It’s a P0088 fault (no description) it won’t let me clear it either (unless I’m doing it wrong in the app🤷🏻*♂️). I decided to uninstall and check. No faults after that. Re-do the install, bam… CEL. What am I doing wrong? It’s literally two connections lol.

    Helped you via email, I think you triggered a fault during install and just needed to delete it properly in the app. Ign on, engine off, delete all faults.
