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. |
The procedures below are designed to program the body control module (BCM) correctly during BCM related service. Before you start, read these procedures carefully and completely.
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
- BPP Sensor Calibration
- Learning the restraints ID
Programming the BCM
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.
From the Main Menu, select Service Programming System, then follow the instructions on the screen. Refer to Service Programming System (SPS) for more information.
BPP Sensor Calibration
Navigate on the Tech 2 to Vehicle Control Systems > Computer/Integrating Systems > Module Setup > Body Control Module > BPP Sensor Calibration, then follow the instructions on the screen.
Learning the Restraints ID
Navigate on the Tech 2 to Vehicle Control Systems > Computer/Integrating Systems > Module Setup > Body Control Module > 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.
