Is Your 2010 Avalanche Experiencing Strange Electrical Issues?
If your truck’s power windows, door locks, interior lights, or security system are acting erratically, the Body Control Module (BCM) is the most likely cause. The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can create a host of frustrating and difficult-to-diagnose problems. This replacement Body Control Module is the definitive solution to restore full functionality to your vehicle’s electronics.
From the Diagnostic Bay
We had a 2010 Avalanche come in with a classic case of BCM failure. The customer complained of the radio turning on and off by itself, the dome lights staying on and draining the battery overnight, and the key fob working only intermittently. After confirming power and grounds were good, we pinpointed the faulty BCM. Instead of a costly trip to the dealership for a new module and programming, we installed one of our VIN-programmed units. The truck was back to normal in under an hour, saving the customer significant time and money.
Common Symptoms of a Failing BCM
- ✔ Power windows or door locks not working or operating on their own.
- ✔ Erratic behavior from the dashboard gauges or warning lights.
- ✔ Vehicle security system faults or failure to start (anti-theft).
- ✔ Interior or exterior lights not working correctly or staying on.
- ✔ Key fob not responding or intermittent operation.
- ✔ Unexplained battery drain when the vehicle is off.

Post-Installation Procedures
While this module is designed for straightforward installation, some vehicles may require additional steps to sync with other onboard systems. Please be aware of the following potential requirements:
- Airbag System Sync: If the airbag warning light is illuminated 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: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as the central hub for these functions.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your truck’s specific options and features. This ensures the module works correctly right out of the box.
Is this part difficult to install?
For the 2010 Avalanche, the BCM is typically located under the steering column. Installation involves disconnecting the battery and swapping the module. It’s a manageable job for a DIYer with basic tools, but we always recommend consulting a service manual.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light is on after I install this?
This can happen. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to resolve this.
