Restore Full Electrical Function to Your GM Vehicle
Are you battling strange and frustrating electrical issues in your 2010 Chevy Suburban or another compatible GM vehicle? Flickering lights, malfunctioning power windows and locks, a security system that acts on its own, or a mysterious battery drain are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of perplexing problems. This replacement Body Control Module, corresponding to part number 25826125, is the definitive solution to restore your vehicle’s functionality and peace of mind.
From the Diagnostic Bay
We had a 2010 Tahoe come in with a complaint of a dead battery every morning. The owner had already replaced the battery and the alternator, but the problem persisted. A parasitic draw test showed a significant power drain even when the vehicle was off. After isolating circuits, we traced the draw to the BCM. It was keeping several interior light and accessory circuits partially active overnight, slowly draining the new battery. Installing a VIN-programmed BCM like this one solved the issue instantly. It’s a reminder that what seems like a battery or alternator problem can often be the computer that controls them.
Is a Failing BCM the Source of Your Problems?
The Body Control Module manages a vast network of non-engine related functions. A fault within this module can manifest in numerous ways, often intermittently at first. This can make diagnosis difficult, but there are common red flags to watch for.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors not working correctly or at all.
- ✔ Vehicle security system engaging randomly or preventing the car from starting.
- ✔ Unexplained battery drain that kills the battery overnight.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Warning lights on the dashboard, such as the airbag or security light.

Don’t waste time and money on a trip to the dealership for expensive programming. We take the hassle out of the repair. When you purchase this module, simply provide us with your vehicle’s VIN. We will program the BCM with the latest GM software specific to your vehicle’s configuration. This ensures that when it arrives, it’s ready for installation right out of the box. This is the most efficient way to get your 2010 Suburban BCM replaced and your truck back to normal.
Important Post-Installation Notes
While this module is programmed for your VIN, some vehicle systems may require a ‘handshake’ procedure after installation. Specifically:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires 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 relearn may be necessary to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about these procedures.
