Are you experiencing frustrating electrical problems in your GM truck or van? A faulty Body Control Module (BCM) is often the culprit behind a host of perplexing issues. The BCM is the central command center for your vehicle’s body electronics, managing everything from your power windows and locks to your interior lighting and security system. When it fails, it can make your vehicle unreliable and difficult to operate. This replacement BCM is the definitive solution to restore full functionality and peace of mind.
This unit arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We flash it with the latest GM software updates, ensuring optimal performance and compatibility right out of the box. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money. Simply provide your VIN during checkout, and we’ll handle the rest.

Expert Pro Tip
Before replacing your BCM, always check the condition of your vehicle’s battery and main ground connections (especially the one from the battery to the chassis and engine block). A weak battery or a corroded ground can cause low voltage conditions that mimic BCM failure, leading to an incorrect diagnosis. A simple check can save you from replacing a perfectly good part.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on or not working at all.
- ✔ The security system light flashing, or the vehicle refusing to start (Passlock/Passkey issues).
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers behaving erratically or not parking in the correct position.
- ✔ False warnings or messages appearing on the driver information center.

Post-Installation Information
While this BCM is programmed for your vehicle, certain systems may require a relearn or synchronization procedure after installation. These are typically straightforward and can sometimes be performed with a high-end diagnostic scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is necessary to sync the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
