Introduction
The procedures below are designed to set-up the body control module (BCM) correctly during BCM related service. Before you start, read these procedures carefully and completely.
Important: The following procedures must be followed:
- Programming the BCM
- Programming Theft Deterrent System Components, if equipped with Passlock System
- Relearn Restraints ID
Programming the BCM
Important: 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 Service Programming System (SPS) in Programming.
Programming Theft Deterrent System Components
Important: This procedure has to be performed only for vehicles equipped with Passlock System.
Perform the Programming Theft Deterrent System Components in Theft Deterrent after successfully finishing the Setup New BCM procedure. If the Programming Theft Deterrent System Components in the Theft Deterrent procedure is not performed after a BCM replacement, one of the following conditions will occur:
| • | The vehicle will not be protected against theft by the Passlock System. |
| • | The engine will not crank or start. |
Relearn Restraints ID
Perform the special function for BCM "Setup SDM Serial Number in BCM" with the scan tool.
Important: After programming, perform the following to avoid future misdiagnosis:
- Turn the ignition OFF for 10 seconds.
- Connect the scan tool to the data link connector.
- Turn the ignition ON with the engine OFF.
- Use the scan tool in order to retrieve history DTCs from all modules.
- Clear all history DTCs.
