99 300m,,has anyone here had a code come up without a actual p number called single board engine controller bus failure,,if u did what was your repair,,in at my wits end trying to diagnosis this thing,,any advice,,,thanks

 

What is the actual code?? If P0601 that is a PCM failure. Need more info, symptoms, code etc....

 

that's what I was trying to say,,my 6000 dollar scanner didn't give me a actual number,,it just said single board engine controller bus failure,,if engine won't turn over,asd relay clicking,,did the usual checking,,i unplugged every powertrain sensor and clicking won't stop,,,any ideas

 

fyi,,,the pcm is about a year old,the pcm I got from a company who rebuild them and they programmed it with the proper skim and proper parameters

 

Hi, where are you located ?
I have a DRB III and coul probably read the proper code for you.

I'm in Montreal, Canada
