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 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.
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 completed:
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.
- Programming the BCM--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--Refer to Brake Pedal Position Sensor Calibration .
- Learning the restraints ID--Navigate on the Tech 2 to Vehicle Control Systems > Module Setup > Body Control Module > Setup SDM Primary Key in BCM, then follow the instructions on the screen.
Important: After any programming or setup, 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.
