Restore Your Vehicle’s Brain and End Electrical Chaos
Are you battling frustrating and unpredictable electrical issues in your GM truck, van, or SUV? Flickering lights, malfunctioning power windows and locks, strange warning messages, or even a vehicle that refuses to start are all classic signs of a failing Body Control Module (BCM).

Expert Insight: The Critical Role of VIN Programming
Why is VIN programming so important? In modern GM vehicles, the BCM is not a one-size-fits-all part. It communicates with dozens of other modules and needs to know the exact options your vehicle was built with—from the type of radio and climate control to whether you have a sunroof or power-folding mirrors. A generic, non-programmed module from a salvage yard will cause features to stop working or create new error codes. Our VIN programming service ensures this Programmed 25847589 Body Control Module integrates seamlessly, just like the original, restoring your vehicle to its factory-correct operational state.

Important Post-Installation Information
While this Programmed 25847589 Body Control Module is designed for a straightforward installation, some vehicles may require additional calibration steps to ensure all systems communicate correctly. These procedures require a professional-grade scan tool and may include:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the systems.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be required for proper brake light and traction control function.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine. This includes power windows, locks, seats, mirrors, interior/exterior lighting, the security system, and more.
How do I know if my BCM is failing?
Common symptoms include erratic behavior of electronic features, such as lights flashing, windows not working, or the horn going off randomly. You may also experience a no-start condition due to the security system or see various warning lights on your dash. A diagnostic scan showing communication errors with the BCM is also a strong indicator.
Is this module difficult to install?
The physical installation is typically straightforward, involving disconnecting the battery and swapping the old module with the new one. The location varies by model but is often under the dash. The most difficult part is typically the programming, which we handle for you before shipping, making the process much simpler.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and calibrations for your vehicle’s specific features and options. This step is essential for ensuring all systems work correctly after installation and is a service that would otherwise need to be done at a dealership.
What happens after I install it?
After installation, most of your vehicle’s functions should be restored immediately. However, as noted above, some vehicles may require an additional procedure like an airbag system sync or a brake pedal position relearn, which must be performed with a compatible professional scan tool.
Does this part replace other part numbers?
Yes, this module is a direct replacement for over 30 different GM part numbers. Please check the comprehensive list in the description above to confirm it is the correct replacement for your original BCM.
