Is Your Vehicle Plagued by Electrical Gremlins?
If you’re experiencing bizarre electrical issues in your Cadillac SRX or other compatible GM vehicle, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central nervous system for your car’s body electronics, controlling everything from power windows and locks to interior lighting and the security system. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems.
From the Diagnostic Bay
We recently had a 2008 GMC Acadia (which uses this exact BCM) come into the shop with the owner at their wit’s end. The dashboard lights would flicker randomly, the radio would sometimes not turn on, and occasionally the power liftgate would refuse to open. They had already replaced the battery and checked the alternator. After connecting our diagnostic tool, we saw multiple communication fault codes pointing to the BCM. We installed a VIN-programmed 2007-2009 SRX Body Control Module, performed a quick brake pedal position relearn, and all the phantom issues vanished. It’s a common story with a simple solution.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The security system acting up or preventing the car from starting.
- ✔ Dashboard warning lights appearing intermittently.
- ✔ Wipers or horn activating on their own or not working when needed.
- ✔ Communication errors with other vehicle modules (U-codes).
The Simple, Reliable Solution
Don’t let a faulty BCM keep you off the road or force you into an expensive dealership visit. This replacement Body Control Module is the perfect, cost-effective solution. We take the hassle out of the repair by programming the module to your vehicle’s specific VIN before we ship it. This ensures compatibility with your vehicle’s options and installs the latest software updates from GM, often resolving issues that the original software had. This is a direct-fit replacement for part number 25910474 and many others.
Post-Installation Requirements
While this module is programmed for your vehicle, some simple synchronization procedures may be required after installation to ensure all systems communicate correctly. These are standard procedures for this type of repair.
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with your vehicle’s airbag system.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure your brake lights and traction control system function correctly.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
Do I need to program this module?
No. We handle the programming for you before shipping. Simply provide your vehicle’s VIN after purchase, and we will flash the module with the latest GM software specific to your car.
How do I provide my VIN?
You can add your VIN to the order notes during checkout, or we will contact you via email after your purchase to request it. We cannot ship the part until we have programmed it.
Is this part truly plug-and-play?
It is pre-programmed to be as close to plug-and-play as possible. However, due to the complexity of modern vehicle systems, you may need to perform additional relearn procedures for the airbag system or brake pedal position sensor, as described above.
What happens if the airbag or brake relearn is not performed?
If the airbag system sync is required and not performed, the airbag warning light will remain illuminated on your dash. If the brake pedal relearn is needed, you may experience issues with brake light operation or traction control/stability control system warnings.
Is there a core charge?
No, there is no core charge for this part. You can keep your old module.
