3. Turn ON the ignition, with the engine and all accessories OFF.
4. Program the BCM. Refer to Service Programming System (SPS) in Programming.
5. Setup the sensing and diagnostic module (SDM) serial number in the BCM. Select Setup SDM Serial Number in BCM with the scan tool.
6. Perform the Programming Theft Deterrent System Components in Theft Deterrent.
7. Program the key fobs. Refer to Transmitter Programming in Keyless Entry.
8. Clear all diagnostic trouble codes (DTCs) with the scan tool.

After the procedure is completed, the personalization settings of the BCM are set to a default setting. Inform the customer that the personalization must be set again. Refer to Vehicle Personalization in Personalization.

If the SDM has been replaced, perform the following steps in order:

1. Connect a scan tool to the DLC.
2. Turn ON the ignition, with the engine OFF.
3. Select Setup SDM Serial Number in BCM with the scan tool.
