Well guys today i decided to move my wiring harness up into the cowl where the winsheild wipers are. Anyway i got everything moved up there and the PCM where i wanted it and plugged everything back in and turned the key and i got a no bus code in the display...whats going on???
 
also i have the ground connected to the battery and the other one that mounts to the mounting hole of the pcm goes the the cowl...im stumped, all i did was unplug it and move it around
 
Good luck is about all I can say. Messing with wiring is one of those things you almost have to be there. The only thing I can suggest is make sure you have all the wires conneected and trace each one. Is it grounded? did you cut any wires?
 
ive wanted to move mine outta the way for some time. couldnt really figure out where to put it.

how hard was it?

i would think something is still unplugged? thats all i got
 
i will get pics of where i moved it later today im at school now. I did not cut any wires, i simply unplugged everything and moved it to where i wanted and plugged everything is plugged in. Both grounds are hooked up too
 
Did you yank on the wires? I moved a harness one time and wanted it in a spot where it didnt want to go so I had to pull the harness a little, when I did it pulled a wire loose from the connector, it didnt pull it out just moved the pin enough to not make a good connection. Thought I did everything right but it wouldnt start so I searched for a few days and eventually pushed all the pin into the connector from the backside, hooked the connector back to the computer and it fired right up.
 
CCD bus to my knowledge transfers info from the PCM, overhead console, etc. There is problaby just a lose connector somewhere. I have a CD with the 2001 wiring diagrams on it that shows all the bus connections. If it would help, I can try to get you a copy of the sheets individually. The whole .pdf file is HUGE.

Check the connectors shown. This is the CCD bus.
