Suspension fault garage hooked up a snap on obd revealing no voltage to exhaust port any ideas on where to look and what cables go to exhaust port colour and so on or is there a fuse I suspect the spare wheel might of crushed some of the loom feeding the compressor but I can’t see any breaks l322. Westminster 2012 it look like the hitachi compressor . I’ve also got an autel maxis 200 with lr software seems good I haven’t made friends with it yet navigating through and interpreting all the info , is the gap better thanks

Not an expert but I’d be undoing the exhaust filter, as that usually gets blocked over time.

Easy fix if it’s that.
