[Shop-talk] Parts annoyance

[Jack Brooks]

Everybody must use the same computers.  27 computers was the same number the Subaru dealer used to try to push us into buying the extended warrantee.  

I’m thinking an chip on a board is considered a computer for warrantee purposes..........

All the electronics that is going into vehicles is hard to deal with troubleshooting even with factory equipment. We need to more thoroughly train mechanics in these areas, & fast!

A friend of mine has a (I think) out of warranty 2017 F150 that works in fine except the radiator fan would always run @ full speed. The dealer couldn’t figure out what the problem was after 3 days so she bought a new truck so she wouldn’t have to listen to it. She was told that there were 27 computers in the truck & if any of them was bad it could cause odd problems not related to what that computer controlled. 
Glad you could troubleshoot the problem rather than shotgunning it as a lot of technicians would do. 

Peace,
Pat

I was working on a Ford e450 with a giant parasitic draw. (6+ amps , key off). Tracked the problem down to the pcm not shutting down, because the instrument panel computer didn’t tell it was in park. (Why does the pcm trust the transmission for everything but park?)  the failed part, a switch connected to the shift interlocking, is $20, but not available until “June or July “.  Turns out the switch actually works, but some knuckle head plugged it in wrong and bent the pins. I took the connector apart, straightened the pins enough to plug it in and then reassembled the connector.  Everything works, but it feels hackish. (Less hackish than the backup
Plan to solder it together, I guess?).
