Is Your Suburban Experiencing Bizarre Electrical Issues?
If your 2010 Chevrolet Suburban 1500 is acting possessed—with flickering lights, malfunctioning power windows or locks, or random warning messages on the dash—a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and unpredictable problems. This isn’t just an inconvenience; it can affect your vehicle’s security and safety. Restore order and reliability with this direct-fit, VIN-programmed Body Control Module.
From the Diagnostic Bay
We had a 2010 Suburban 1500 towed in that was baffling its owner. The interior lights would stay on, draining the battery overnight, and the power door locks worked intermittently. The owner had already replaced the battery twice. After running diagnostics, we traced the parasitic draw and erratic behavior directly to a faulty BCM. Instead of a costly and time-consuming trip to the dealership, we installed a VIN-programmed module just like this one. The electrical gremlins vanished, and the customer was back on the road the same day with a perfectly functioning truck.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, mirrors, or door locks not working correctly.
- ✔ The security system or keyless entry failing to operate.
- ✔ Unexplained warning lights on the instrument cluster (like the airbag light).
- ✔ A battery that drains overnight for no apparent reason (parasitic draw).
- ✔ Horn honking randomly or not working at all.
Installation and Programming for Your 2010 Suburban 1500 BCM
The biggest hurdle in replacing a BCM is the programming. Dealerships can charge a significant amount for this service alone. We eliminate that step. When you purchase this module, you simply provide us with your vehicle’s VIN. We then program the BCM with the latest GM factory software specific to your Suburban’s options and features. This ensures that when you receive the part, it’s ready for installation, saving you time and money. While the installation is largely plug-and-play, some vehicles may require simple post-installation procedures.
Post-Installation Requirements
After installing your new BCM, a couple of additional steps might be necessary to ensure all systems communicate correctly:
- Airbag System Sync: If your airbag warning light illuminates after installation, a technician will need to perform a ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure your brake lights and traction control system function as intended, a brake pedal position sensor recalibration may be required.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
This module is a direct replacement for a wide range of part numbers, including 15921353, 25892622, 20815898, and many more. It fits a variety of GM trucks, SUVs, and vans. Please verify the part numbers and fitment list to ensure compatibility with your vehicle.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle the programming for you before we ship the part. Simply provide your vehicle’s VIN during checkout, and it will arrive with the latest GM software, ready for installation.
Where is the BCM located on a 2010 Suburban 1500?
On the 2010 Suburban 1500, the Body Control Module is typically located under the driver’s side of the dashboard, near the steering column.
What happens if I forget to provide my VIN?
We cannot ship your order without a VIN. The programming is essential for the module to work with your specific vehicle. We will contact you to get the VIN before we can process and ship your part.
Will this fix my airbag light?
If the airbag light is on due to a fault within your old BCM, this part will resolve the root cause. However, after installation, the system may require an ‘Airbag System Sync’ with a diagnostic tool to turn off the light.
Is this a simple plug-and-play installation?
For many vehicles, it is. You disconnect the battery, swap the module, and reconnect. However, as noted, some models may require additional relearn procedures for systems like the brake pedal position sensor to function correctly.
