1999 Ford Expedition Repair Question
Mileage: 190,142 miles.
Trying to program a new ecm
Through troubleshooting it was determined that the instrument cluster needs to be replaced but I am not so sure of that since there wasn't a problem with it before..Also,doing a check of the IC it seems to be working fine,,all guages doing a sweep and all lights working as well..Please help..Thank you in advance.
what kind of flash program are you using. i used the borg warner and had issues doing this.
i'm using the Snap-on Pass Thru Pro II..Also used the ford Programmer with the same results..
then the actual pcm may be at fault. call ford and get another one, assuming you are using a new one??
I'll try thatr
BTW: The original ECM also now has the same codes and it is doing the same thing..
how did you determine the pcm was bad??
#1 & #6 cylinders were missing..when I went through the diagnostic step i found that the driver in the ecm was not working..
