Introduction
A new body control module (BCM) must be programmed with the latest operating software and vehicle calibrations. Ensure that the following conditions exist in order to prepare for BCM programming:
| • | The battery is fully charged. |
| • | The ignition switch is in the ON position. |
| • | The data link connector (DLC) is accessible. |
| • | All disconnected modules and devices are connected. |
Programming the BCM
Important: The vehicle will not start and many other functions may not operate properly if a replacement BCM is not properly set up. The following procedures must be followed:
- Programming the BCM
- Learning the restraints ID
Important: After the procedure is completed, the personalization settings of the BCM are set to default settings. Inform the customer that the personalization must be set again.
Learning the Restraints ID
Navigate on the scan tool to Body Control Module > Module Setup > Setup SDM Primary Key in BCM, then follow the instructions on the screen.
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.
