Can anyone tell me what this fault code is all about please. It popped up CReader V but not on either ACR4 G2 or ACT2. Car runs fine before and after re-mapping and was there prior to re-map. The query is out of curiousity and might be just a software error. I am aware the vehicle is before EOBD compliancy.

Regards
