I replaced the BCM in my Hummer with a used one. Old one was destroyed by a sunroof leak. Mileage was 157xxx and the new one reads 193xxx. I don't know the EXACT mileage from before. Can anything be done to find that, and restore it correctly?

You would need to send in both the cluster and BCM. Also, the original VIN number if one of the two units is from another car.
