Is your 2010 Chevrolet Avalanche suffering from strange and unpredictable electrical problems? A faulty Body Control Module (BCM) is often the culprit. The BCM acts as the central command center for your truck’s body electronics, managing everything from power windows and door locks to interior lighting and the security system. When it fails, it can cause a cascade of frustrating issues that seem to have no logical explanation.
This is a direct-fit replacement Body Control Module, delivered to your door fully programmed and ready for installation. We take the guesswork and expensive dealership trips out of the equation. Simply provide your vehicle’s VIN at checkout, and our technicians will flash the module with the latest, most stable software from GM, ensuring it’s a perfect match for your truck’s specific options and configuration. Restore functionality and peace of mind with a reliable, plug-and-play solution.
From the Diagnostic Bay
We had a 2010 Avalanche in the shop that was driving its owner crazy. The radio would turn on by itself, the driver’s side window would randomly roll down, and the security light would flash intermittently, sometimes preventing the truck from starting. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication error codes pointing to the BCM. A new, programmed BCM fixed every single issue. It’s amazing how one faulty module can create so many ‘ghost’ problems.
Diagnosing a Faulty 2010 Avalanche Body Control Module
A failing BCM can manifest in numerous ways, often making you think multiple components have failed at once. If you’re experiencing several of the following symptoms, your BCM is the likely cause.
Common Failure Symptoms:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior dome lights or exterior lights staying on or not turning on at all.
- ✔ The security or anti-theft system light is illuminated, possibly causing a no-start condition.
- ✔ Intermittent operation of the radio or HVAC climate controls.
- ✔ False warnings on the driver information center (DIC).
- ✔ Horn not working or sounding randomly.
Post-Installation Requirements
While this module is programmed for your VIN, some vehicle systems may require a ‘relearn’ or synchronization procedure after installation. This is a normal part of the repair process. The most common procedures include:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor recalibration may be necessary.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We handle all the programming for you before shipment. Just provide your vehicle’s VIN number during checkout, and the module will arrive ready to install.
Is this a difficult part to install?
For a moderately experienced DIYer, the installation is straightforward. The BCM is typically located under the steering column. It involves disconnecting the battery, removing a few trim panels, and swapping the module. The key is taking your time and being careful with the plastic clips and electrical connectors.
What does ‘No Core Charge’ mean?
It means you do not have to send your old, faulty BCM back to us. You can keep it, recycle it, or dispose of it as you see fit, with no extra fees.
What happens if my airbag light is on after I install the new BCM?
This is a common occurrence. The new BCM needs to be synced with your vehicle’s airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by any professional shop with a compatible diagnostic tool.
Will this part fit other vehicles besides the 2010 Avalanche?
Yes, this BCM is compatible with a wide range of GM vehicles. Please check the detailed fitment list on this page and ensure your original part number is listed to guarantee compatibility.
