We offer off car Body Control Module Programming for the 03-07 Classic GM Trucks / SUV's. When sending us any Body Control Module please include the VIN Number of the vehicle that the BCM will be going in. THE VEHICLE IDENTIFICATION NUMBER IS LOCATED ON THE FRONT LEFT OF THE DASH DOWN AT THE BOTTOM OF THE WINDSHIELD. YOU CAN ALSO FIND THE VIN ON THE DRIVERS DOOR LOCATED ON THE MANUFACTURE ID TAG. Please notify us if the vehicle is equipped with remote key less entry as this is specific to the programming process. Installing the Replacement BCM in the 03-06-07 Classic truck is very straight forward and is outlined below. The correct procedure is to log into the GM SPS Terminal and preform the 10 minute VTD Relearn. At the terminal window select Replace then next for the VTD Relearn selection. If you do not have access to the Tech Terminal a 30 minute relearn procedure must be preformed. Place a Jump pack on the vehicle. Do not let the battery drop below 11.5 volts. 1. Try and start the vehicle. Return the key to the run position. Wait 10 minutes. (10) 2. Turn the key from run to off. Return the key back to the run position. Wait 10 minutes. (20) 3. Turn the key from run to off. Return the key back to the run position. Wait 10 minutes. (30) 4. After the final 10 minutes return the key to the off position. The next cycle of the key will now re-learn the Passlock data into the replacement module. Personalization SETTINGS in the Driver Information Center may need to be reset. Please consult your OWNER'S manual for vehicle personalization.
