pcm ..no communication
pcm wasn't communicating with diacnostics...replaced it and still not reading. replaced the wires as well..any ideas?
i haven't but i sure hope canadian tire did since i paid for diagnostics. where is it located so i can check it?
probably in the interior fuse box, if it has one. check the map on the fuse box cover for anything that says DLC. DLC = data link connector, which is the diasgnostic port
is there power at the DLC? meaning when you plug the scan tool in, does it power up the tool?
yup. yhey even ran a seperate wire to make sure there wasnt a short . they're absolutely lost. my only hope was to see if anyone else had this problem
ive seen this before with a lot of cars, but its never been the same reason twice, or easy to fix.
don't know if this has anything to do with it but code 21 (speed control solenoid ) or somethinb like that pops up too
in a Chysler when the scanner wont comunicate,the computer is bad,replace it,a used one will work.
