Is your 2010 Chevrolet Avalanche suffering from bizarre electrical problems? You’ve likely found the culprit: a failing Body Control Module (BCM).
The BCM is the central nervous system for your truck’s body electronics, managing everything from power windows and door locks to the security system and interior lighting. When it starts to fail, it can create a cascade of frustrating and seemingly unrelated issues. This isn’t just an inconvenience; it can affect the safety and security of your vehicle.
This replacement Body Control Module is the definitive solution. It arrives at your door fully programmed to your vehicle’s specific VIN number with the latest GM software updates. This means you can skip the expensive trip to the dealership for programming. Just provide your VIN after purchase, and we’ll handle the rest, ensuring the module is ready for installation right out of the box.
From the Diagnostic Bay
We recently had a 2010 Tahoe, which shares this BCM, in the shop with a list of strange symptoms. The radio would randomly shut off, the door locks would cycle while driving, and the security light would flash intermittently. The owner had already replaced the battery and checked all the fuses with no luck. A diagnostic scan pointed to communication loss with the BCM. Installing a VIN-programmed 2010 Avalanche Body Control Module like this one immediately cleared all the phantom electrical faults and restored the vehicle to perfect working order.
Common Failure Symptoms
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Flickering or inoperative interior and exterior lights.
- ✔ Security system faults or the engine failing to start due to anti-theft issues.
- ✔ Erratic behavior from the radio, climate controls, or instrument cluster gauges.
- ✔ False warning messages on the driver information center (DIC).
- ✔ A/C compressor not engaging.
Installing Your 2010 Avalanche Body Control Module
Because this module is pre-programmed to your VIN, the physical installation is straightforward. However, depending on your vehicle’s specific configuration, a couple of simple post-installation relearn procedures may be required. These are standard industry procedures that a qualified technician can perform quickly.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a professional scan tool. 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 correct brake light operation and to keep the traction control system happy.
Note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
