Immobiliser blocking start

Post by littlepolo »

I had this problem a few times in recent months and decided to examine the instrument cluster for any dry joints. On removal and inspection of the cluster I could not see anything obvious but re-flowed the rightmost joints on the PCB data connector and some of the leftmost side too. Of course, the immobiliser had reset in the meantime. Will update if the problem recurs.
