Is Your 2010 Avalanche Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, a dashboard that’s lit up like a Christmas tree, power windows with a mind of their own, or a truck that refuses to start, you’re not alone. These are classic symptoms of a failing Body Control Module (BCM), the central nervous system of your vehicle’s electronics. In my 20+ years as a diagnostic technician, I’ve seen how a faulty BCM can turn a reliable truck into a source of constant frustration. A customer’s 2010 Avalanche came into my shop last week with the radio cutting out and the ‘Service StabiliTrak’ light flashing intermittently. After confirming the battery and grounds were solid, the scan tool confirmed what I suspected: an internal BCM communication error, a common issue on these GMT900 platforms.
The Direct Solution: A VIN-Programmed BCM
Don’t let a dealership charge you a fortune for a new module and the mandatory programming. This Body Control Module is the straightforward, cost-effective solution you need. We take the hassle out of the repair by programming the module specifically to your truck’s Vehicle Identification Number (VIN) before we ship it. This means it arrives at your door loaded with the latest GM software updates, ready for installation.
Expert Pro Tip from a 20-Year Veteran
Before you plug in your new BCM, take 30 seconds to inspect the harness connectors. Look closely for any greenish-white powder (corrosion) or any pins that look pushed back into the connector. A poor connection can cause the exact same symptoms as a bad module and is a leading cause of repeat failures. Cleaning the terminals with a contact cleaner can save you a major headache down the road.

Simple Installation Process
Replacing the BCM on your 2010 Avalanche is a manageable job for a confident DIYer. The module is typically located under the driver’s side dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your truck’s battery.
- Locate the BCM: Find the module under the driver’s side dash. It will have several large electrical connectors attached.
- Disconnect and Remove: Carefully unclip all electrical connectors. Release the mounting tabs or bolts holding the old BCM in place and remove it.
- Install the New Module: Seat the new, pre-programmed BCM in the mounting bracket and securely plug in all the electrical connectors.
- Reconnect Power: Re-attach the negative battery terminal.
Important Post-Installation Steps
After installing your new 2010 Avalanche 1500 Body Control Module, a few final procedures are necessary to ensure all systems communicate correctly. This is a critical step for safety and functionality.
- Airbag System Reset: The ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible high-level scan tool. This step is required to clear the airbag warning light and ensure the safety system is operational.
- Brake Pedal Position Sensor Relearn: Your vehicle may require a brake pedal position sensor relearn or recalibration. This ensures the BCM receives accurate input for systems like StabiliTrak and cruise control.
Note: While this is a plug-and-play part regarding programming, these relearn procedures are essential. If you do not have access to a bi-directional scan tool, we recommend seeking assistance from a qualified local mechanic to complete the installation.
