Vehicle was missing on #1 & #6 cylinders. Driver in Ecm was determined to be at fault. Replaced ecm, tried to program, it won't accept the programming.I was then given codes P0603, P1260, B2139, U1147 & B1845. All of which were not there prior to replacing ecm. Codes that were there prior to replacing ecm were P0351, P0352, B1202, B1323, B1318, B1410, P1137, P1157, P1408, P1131 &P1151.
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?

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.
