Are you experiencing frustrating and unpredictable electrical problems in your Cadillac Escalade or other compatible GM vehicle? Issues like flickering interior or exterior lights, malfunctioning power windows and locks, or a security system that acts up on its own are often signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing symptoms. This replacement BCM, part number 25847589, is the definitive solution to restore your vehicle’s electronic functions to perfect working order.

Installation and Post-Install Notes
While this module is designed for a direct fit, some vehicle systems may require a recalibration or ‘relearn’ procedure after installation. This is a normal part of the process. For example, if the airbag warning light is illuminated after installation, a professional scan tool will be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ may be necessary to ensure proper brake light and traction control function. Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the central computer for your vehicle’s body-related accessories. It controls functions like power windows, power mirrors, power locks, interior and exterior lighting, the anti-theft system, and the climate controls, among other things.
Why do you need my VIN?
Your vehicle’s VIN allows us to program the BCM with the correct software and vehicle-specific options before we ship it. This ensures the module communicates correctly with the other computers in your vehicle, saving you a trip to the dealership for expensive programming.
Is this part difficult to install?
For someone with moderate mechanical skill, the physical replacement is typically straightforward. It’s often located under the dashboard. However, as noted, some post-installation electronic relearn procedures may be required, which might necessitate a professional-grade scan tool.
What happens if my airbag light is on after installing the BCM?
This is a known possibility. The new BCM needs to be synced with the airbag’s computer (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a compatible high-end scan tool to resolve this and turn off the light.
Is there a core charge for this part?
No, there is no core charge. You can keep your old module without needing to send it back to us.
Will this BCM fit vehicles other than the 2010 Escalade?
Yes. This BCM is compatible with a wide range of GM trucks, vans, and SUVs from roughly 2006-2013, including the Tahoe, Suburban, Yukon, Silverado, Sierra, Express, Savana, and more. Please verify your original part number against the list provided to ensure compatibility.
