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.
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.
