The procedure below is designed to set-up the body control module (BCM) correctly after BCM related service. The Service Programming System (SPS) uses the vehicle identification number (VIN) to determine the regular production option (RPO) configuration that the vehicle had when it was built. The SPS programs the BCM with the RPO configuration. After a new BCM is programmed, the powertrain control module (PCM) must learn the new BCM's Passlock fuel enable password. Before you start, read these procedures carefully and completely.

Perform the following steps:

1. Ensure that the battery is fully charged.
2. Connect a scan tool to the data link connector (DLC).
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. Perform the Programming Theft Deterrent System Components in Theft Deterrent.
6. 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.
