Probably, if not, using your VIN the PCM can be re-flashed to your vehicle.

it would seem to make sense, especially if i get the vin from the other car if needed too.

I was reading some things about a bcm being "asleep" the guy I bought the car from installed an aftermarket radio into this thing. Now the car runs but the security light blinks..would this have anything to do with my problem?

Also for Bill C. I could not find 641 in the diagram? I even looked in my book and general vicinity would help. Also, when I tried grounding the ABS/TC motor, it grounded fine from the nut to frame but if I touched the nut to the motor case, nothing. Is that normal or a sign of a short.
Thanks

update

Ok, i have an update on the car.
I am only showing three codes....B0844, P1571, P1644. I cleaned the ignition switch and fully charged the battery. i did rebuild the 4l60e last month so i had a lot of stuff apart on the car. I have two quick questions, what is the the big plug in the left rear well and what is the box that it appears to plug into. my manuals are out at the shop which i wont have access to for a few weeks. also, can i attempt to reground the ebcm to somewhere else in the car?

thanks as always
Spence

ok guys, i paid 50 bucks and had my car on a tech II for while and the problem seems to be with my pcm. i am planning on buying a used harness to start swapping plugs and such. will a harness from an 01 zo6 work on my 97 auto?
thanks

thanks Bill, i am planning on buying a new 97 pcm from a dealership, the one that is in the car now was a refurbished one so hopefully they will take it as a core. I am also planning on buying new pin connector ends and using a guage to test them to see if there is play.
