So I think I found a DRBIII from a friend of a friend to use this weekend, so I can program the last few digits of my VIN into my ECM so I can use my Smarty finally. I have been talking with Bob all week about this, about early 03 trucks missing the last few digits of the VIN int he ECM and posted my problem early this week
So I was wondering does anyone know how to do this with a DRBIII?
The person I am borrowing it from knows nothing and I was hoping that someone could give me step by step instruction so I do not mess anything up. I have use a Tech2 for GM products a bit but never a DRBIII.
Thanks,
Nate
