Restore Control Over Your Truck’s Electronics
Are you tired of dealing with the frustrating and unpredictable electrical problems in your 2010 Chevy Avalanche? One minute the power windows work, the next they don’t. The security light flashes for no reason, or worse, your truck won’t start at all. These aren’t just minor annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your truck’s accessories, and when it malfunctions, it can cause chaos. This replacement BCM is the simple, reliable solution to get your truck back to normal, fast.
We make this repair as straightforward as possible. This isn’t just a part in a box; it’s a complete solution. We pre-program the module with the latest GM software specifically for your truck using the VIN you provide. This means you can skip the expensive trip to the dealership for programming. It arrives at your door ready to be installed, saving you both time and money.
A Technician’s Notebook
I recently had a 2010 Avalanche 1500 in the bay with a classic BCM failure. The customer complained of a phantom battery drain that left him stranded twice. After checking the battery and alternator, I performed a parasitic draw test. The meter showed a significant draw that would disappear the moment I pulled the main BCM fuse. Internally, the module had a short that kept several circuits partially active even when the truck was off. Replacing the faulty unit with a properly programmed 2010 Avalanche 1500 BCM solved the issue instantly. It’s a common failure point I’ve seen dozens of times on these GM platforms.
Is Your Avalanche Showing These Symptoms?
- âś” Intermittent or non-working power windows, door locks, or interior lights.
- âś” The security system light stays on or flashes, preventing the engine from starting.
- âś” Unexplained battery drain that kills a good battery overnight.
- âś” Erratic instrument cluster behavior or warning lights (like ABS or Airbag) that won’t turn off.
- âś” Communication error codes, such as U0140 (Lost Communication With Body Control Module).
- âś” Remote keyless entry fails to work consistently.
A Straightforward Guide to Installation
Installing your new 2010 Avalanche 1500 BCM is a manageable job for a confident DIYer. On the Avalanche, the BCM is typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your truck’s battery before starting any electrical work.
- Locate the BCM: Remove the lower dash panel beneath the steering wheel to gain access to the module. It’s a black plastic box with several large wiring connectors.
- Swap the Module: Carefully unplug all electrical connectors from the old BCM. They have release tabs that need to be pressed. Once disconnected, unbolt or unclip the old module and remove it.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all the wiring harnesses. Ensure each connector clicks into place.
- Reconnect & Test: Reinstall the dash panel, reconnect the negative battery terminal, and start the vehicle. Test all functions like windows, locks, lights, and wipers to confirm the repair.
Important Post-Installation Steps
While our programming handles the heavy lifting, some vehicle systems may require a ‘handshake’ with the new BCM. Depending on your specific vehicle, you may need a professional scan tool to perform the following relearn procedures:
- Airbag System Sync: If your airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor relearn might be necessary.

Frequently Asked Questions
What exactly does a BCM do?
The Body Control Module acts as the central computer for your vehicle’s non-engine related functions. It manages power windows, locks, lights, wipers, the security system, and more, ensuring all your comfort and convenience features work correctly.
Why do you need my VIN number?
Your VIN is essential because it allows us to program the BCM with the specific software and settings for your vehicle’s exact options package. This ensures a seamless, plug-and-play installation without needing a trip to the dealer.
Is this difficult to install myself?
For someone with basic mechanical skills, this is a very manageable repair. The BCM is usually accessible under the dashboard and just requires unplugging the old unit and plugging in the new one. No special programming tools are needed on your end.
What if my airbag light comes on after I install it?
This is a normal possibility. The new BCM needs to be electronically introduced to the airbag system (SDM). A repair shop with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Do I need to return my old BCM?
No, there is absolutely no core charge for this part. You can keep your old module, which saves you the time and hassle of shipping it back.
