Restore Your Vehicle’s Electrical Functions with a Plug-and-Play BCM

Are you dealing with baffling electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts up, or a dashboard lit up with random warnings? These are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your car’s body electronics, and when it starts to fail, it can create a cascade of frustrating and seemingly unrelated problems. Don’t let electrical gremlins take your car off the road or force an expensive trip to the dealership.

We offer a straightforward and reliable solution. This Body Control Module is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This means it arrives ready for installation, loaded with the latest GM software updates to ensure optimal performance and compatibility. You get a part that communicates seamlessly with your vehicle’s other systems, restoring the functions you depend on every day.

Is Your Vehicle Showing These Signs of a Faulty BCM?

• ✔ Erratic or non-functional interior and exterior lights.
• ✔ Power windows, door locks, or mirrors working intermittently or not at all.
• ✔ The security system or keyless entry failing to operate correctly.
• ✔ The horn sounding randomly or not working when pressed.
• ✔ False warning lights appearing on the instrument cluster.
• ✔ Communication errors with other modules, often triggering U-series Diagnostic Trouble Codes (e.g., U0140, U0155).
• ✔ Unexplained battery drain that leaves you with a no-start condition.

Your Straightforward BCM Installation Guide

Installing your new Programmed GM Body Control Module is a manageable job for a confident DIYer or any professional technician. While the exact location varies by model (check your service manual), the general process is consistent.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning work.
2. Locate the BCM: On most of these GM models, the BCM is found under the driver’s side or center of the dashboard, often near the steering column or behind a kick panel.
3. Remove Connectors: Carefully unplug the electrical connectors from the old module. They have locking tabs that need to be depressed to be released. Do not force them.
4. Swap the Module: Unbolt or unclip the old BCM and remove it. Mount the new module securely in its place.
5. Reconnect Everything: Plug the electrical connectors firmly into the new BCM until they click. Reconnect the negative battery terminal.
6. Test Functions: Start the vehicle and test all body electronics: lights, windows, locks, wipers, radio, etc., to confirm the repair.

Important Post-Installation Notes

Because this Programmed GM Body Control Module is new to your vehicle’s network, a couple of simple relearn procedures may be necessary depending on your specific model and its options. This is a normal part of the process.

• Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
• Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure brake lights and traction control function correctly.
• No Core Charge: You can keep your old part; there is no core charge or need to return the original module.

Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step of the process.
