Is your 2010 Suburban 1500 or other GM vehicle experiencing bizarre electrical problems? The Body Control Module (BCM) is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating issues. This replacement Body Control Module, part number 15921352, is the definitive solution to restore full functionality to your vehicle’s accessories and systems.
We take the guesswork and hassle out of the repair process. Unlike a standard replacement part that requires expensive dealer programming, this BCM comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). Simply provide us with your VIN after purchase, and our experts will flash the module with the latest GM software updates, ensuring it’s ready for installation right out of the box. This plug-and-play approach saves you time, money, and a trip to the dealership.
We had a 2010 GMC Yukon in the shop with a classic ‘ghost’ problem. The owner complained of intermittent no-starts and the radio turning on and off by itself. The battery, alternator, and starter all tested fine. After hooking up the scan tool, we noticed multiple communication loss codes with various modules. The culprit was a failing BCM that was corrupting the data network. Replacing the BCM, like this one, resolved all the strange electrical gremlins and got the vehicle running reliably again.
Common Symptoms of a Failing 2010 Suburban Body Control Module
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on or not working at all.
- ✔ The security system acting up or preventing the vehicle from starting.
- ✔ Dashboard warning lights (like ABS, Airbag, or Traction Control) illuminating for no reason.
- ✔ Problems with the radio, climate control, or instrument cluster.
- ✔ A ‘No Communication’ error when a diagnostic scan tool is connected.
- ✔ The engine won’t crank or start, even with a good battery.
Installation and Post-Install Notes
This module is a direct replacement for a wide range of original equipment part numbers, including 15921352, 25892622, 20815898, and many others listed in the fitment guide. While our VIN programming makes the initial installation straightforward, some vehicles may require simple relearn procedures after the new module is installed. These can include:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control function.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and the instrument panel.

Is this part truly plug-and-play?
Yes, for the most part. Because we program it to your VIN, it will not require a trip to the dealer for initial setup. However, as noted, some vehicles may require minor relearn procedures for systems like the airbags or brake sensor after installation.
Where is the BCM located on a 2010 Chevy Suburban?
On the 2010 Suburban, Tahoe, and Yukon, the BCM is typically located under the driver’s side of the dashboard, near the steering column.
