A new body control module (BCM) must be programmed with the proper regular production option (RPO) configurations. The BCM stores the information regarding the vehicle options and if the BCM is not properly configured with the correct RPO codes the BCM will not control all of the features properly. The Tech 2 software will automatically prompt you with the various RPO's available for the vehicle. Ensure that the following conditions exist in order to prepare for BCM programming:
Important: Use extreme care when verifying both the VIN and Odometer reading that is set in the service BCM. Once the VIN and Odometer are set in the replacement BCM it is impossible to change them, and if there is a mismatch, the part will be rendered useless.
To setup a new replacement BCM select Vehicle Control Systems, then navigate to Computer/Integrating Systems, once in the Computer/Integrating Systems menu select Module Replacement/Setup and follow the instructions on the scan tool.
If the BCM fails to accept the program, perform the following steps:
• | Inspect all BCM connections. |
• | Verify that the scan tool has the latest software version. |
If the SDM is replaced the SDM part number must be learned by the BCM. Using a scan tool navigate to Vehicle Control Systems, Module Setup, Supplemental Inflatable Restraints then select Setup SDM Part Number In BCM. Follow the on screen directions.
Important: After programming, perform the following to avoid future misdiagnosis:
