54' S60 2.0T, CEM fault ?

[nobananas]

Hi guys. Had a weird one at work today. Had a 54' S60 2.0t that developed a running issue as the owner drove it to us for refueling. Scanned it and had a list of codes, MAF sensor looked most likely. Cleared the codes and road tested it. Rescanned the codes, MAF code back, cleared it again before righting off the MAF then whilst moving it the brown stuff hit the fan ! Had a Anti Skid malfunction warning on the dash, then noticed that the indicators had stopped working, headlights won't turn off, radio won't turn on etc. A rescan of all systems showed that most modules had suddenly stopped talking to the CEM ! I know the CEM's on these suffer problems due to water ingress but this seems a bit strange that it's happened all at once. I've left the battery off overnight but i don't think it's going to do anything, anyone had anything similar happen ?

Thankfully it turned out to be a blown fuse ! Stopped my heart for a little while though !

Crisis over :)

Bloody fuses, so much sensitive stuff in cars these days only takes one little thing to trigger a meltdown

2004> cars had the modification done to the CEM to combat the water ingress to the wiring harness. So it's wouldn't have been that anyway.
