Restore Your Truck’s Electrical System with a Plug-and-Play BCM
Are you battling bizarre electrical issues in your 2010 Chevrolet Avalanche? Flickering lights, power windows with a mind of their own, or a security system that randomly prevents you from starting the engine are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause widespread and frustrating problems. This isn’t just an annoyance; it’s a reliability issue that can leave you stranded. We offer a dependable, straightforward solution: a replacement BCM programmed specifically for your truck’s VIN.
Case Study: A Tricky Diagnosis
I remember a 2010 Avalanche that came into my shop with a complaint that would drive any owner crazy. The interior lights would flicker, the radio would cut out, and occasionally, the truck just wouldn’t start—no crank, nothing. The owner had already replaced the battery and checked the alternator. When I connected my scan tool, I found a slew of ‘U’ codes, like U0140 (Lost Communication with BCM), pointing to a network problem. Instead of a complex wiring issue, experience told me to look at the BCM itself. After swapping in a pre-programmed module, every single one of the ghostly electrical problems vanished. This is a common failure, and this module is the direct fix.
Is Your Avalanche Showing These Symptoms?
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lights (flickering, staying on, or not working at all).
- ✔ The security or anti-theft system light is on, preventing the engine from starting.
- ✔ False warnings on the instrument cluster (e.g., ‘Service 4WD’ or ‘Service StabiliTrak’).
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or U0100.
- ✔ Remote keyless entry (RKE) system not responding.
A Straightforward Guide to Installation
Replacing the 2010 Avalanche Body Control Module is a manageable job for a DIYer with basic tools. Our VIN programming service means you can skip the expensive trip to the dealership for software flashing.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before starting work.
- Locate the BCM: On the 2010 Avalanche, the BCM is typically located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount the new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Relearn Procedures: Start the vehicle. In some cases, you may need to perform additional procedures. If your airbag light is on, a professional scan tool is needed for the ‘Setup SDM Primary Key’ function. A ‘Brake Pedal Position Relearn’ may also be required for proper brake light and traction control operation.

Frequently Asked Questions
What does ‘VIN Programmed’ mean?
It means we load the module with your truck’s specific software using your Vehicle Identification Number (VIN). This makes the part plug-and-play, saving you from a costly programming service at a dealership. Simply provide your VIN at checkout.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module without any additional fees.
Will this fix my ‘Service StabiliTrak’ message?
While a faulty BCM can cause this message, other issues like a bad wheel speed sensor or steering angle sensor can also be the culprit. A proper diagnosis is recommended, but if you have other BCM-related symptoms, this is a very likely solution.
What tools are required for installation?
Basic hand tools like a socket set and a trim removal tool are usually all that’s needed to access and replace the BCM. No special programming tools are required from your end.
What if my airbag light comes on after installation?
This can happen occasionally. It requires a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the airbag system. Most repair shops can perform this service for you.
