So today I decided to change the throttle body return hose because there was a crack in the rubber at the throttle body end. In order to dissconnect and remove it from the overflow tank I moved the fuse box out of the way. When doing this I briefly shorted BeCM contact #3 which is underneath the box to the rectangular post that holds up the fuse box. Now I get a dashboard display saying Fuse 12, 13, 14 and 15 have failed but they are all good. I cannot shift out of Park because the BeCM thinks that fuse has failed (I guess). The right headlight which is supposed to be a daytime running light is off. When I shut off the engine I can hear a relay clicking in the BeCM but if I open the driver's door this stops.
I dissconnected the battery and reconnected. At some point I am getting a Diagnostic Mode message on the display and the key does nothing in that case but eventually I was able to start the car and move it. If I then shut it off I go back to the display showing failed fuses and cannot get out of park. When I first used my Hawkeye it found a bunch of communication faults and maybe some others which I cleared. Now it does not find any faults in Body Electrics. Right now I have the battery dissconnected and tomorrow I will check all the fuses again and maybe switch out any potentially related relays. Any thoughts from the BeCM gurus would be much appreciated.
