The Body Control Module (BCM) in your 2010 Chevy Malibu is a critical component responsible for managing various vehicle functions. If you’re replacing your BCM, careful programming is crucial. This guide outlines the programming and setup procedures for a new BCM in a 2010 Chevy Malibu.
Programming a New BCM
When setting up a replacement BCM, ensure accurate VIN and odometer readings. Once programmed into the BCM, these values are permanently locked. Any mismatch renders the BCM unusable.
To begin, connect a compatible scan tool to your vehicle’s OBD-II port. Navigate through the scan tool menu: Vehicle Control Systems -> Module Setup -> Body Control Module.
If the scan tool establishes communication with the existing BCM, select BCM Copy and Flash. This option transfers existing data to the new module. If communication fails, choose BCM Setup to manually configure the new BCM.
Post-Programming Procedures
After completing the BCM setup, perform the Remote Start Setup procedure if your vehicle is equipped with this feature. Consult your vehicle’s service manual or the scan tool instructions for detailed guidance on this process.
Troubleshooting Programming Issues
If the BCM rejects the programming attempt, check the following:
- BCM Connections: Inspect all connections to the BCM for damage, looseness, or corrosion. Ensure they are securely fastened.
- Scan Tool Software: Verify that your scan tool is running the latest software version. Outdated software can cause compatibility issues.
Remote Start Calibration (If Equipped)
Remote start calibration requires a Techline Terminal and the Pass-Thru programming method. With the scan tool powered off, connect it to the vehicle and then connect the Techline Terminal’s RS-232 cable to the scan tool. Power on the Techline Terminal and select Service Programming System. Choose the Pass-Thru procedure and follow the on-screen prompts. Select the correct programming procedure for the BCM. Configure the remote start features to match the original RPO (Regular Production Option) configuration of your vehicle. This ensures all remote start functionalities operate as intended.
