Is your Cadillac CTS or other GM vehicle plagued by bizarre electrical problems? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts on its own are 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 cascade of frustrating and difficult-to-diagnose symptoms. Restore full functionality and peace of mind with our pre-programmed BCM, a direct-fit solution for part number 25892622.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. Upon purchase, simply provide us with your vehicle’s VIN. Our experts will then flash the module with the latest, most stable software from GM, ensuring it is perfectly matched to your vehicle’s specific configuration. This eliminates the need for expensive dealership programming, saving you time and money.
From the Diagnostic Bay
We had a 2011 Cadillac CTS come in with the owner convinced he needed a new alternator and battery. The interior lights would pulse, the radio would cut out, and sometimes the car wouldn’t start, but the battery always tested fine. After chasing grounds and checking the charging system, we hooked up the scan tool and found a slew of communication codes all pointing back to one culprit: the BCM. The internal circuitry was failing, causing voltage drops across various systems that mimicked a charging problem. A new, VIN-programmed BCM fixed everything instantly. It’s a reminder that what seems like a power supply issue can often be a control module problem.
Symptoms of a Failing 2008-2013 CTS Body Control Module
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Communication errors with other vehicle modules (DTC U-codes).
- ✔ Unexplained battery drain when the vehicle is off.
Installing this BCM is straightforward for a DIYer with moderate experience or any professional technician. Once installed, some vehicles may require a simple relearn procedure. For example, if the airbag light illuminates, a ‘Setup SDM Primary Key in BCM’ procedure may be needed using a professional scan tool. Similarly, a Brake Pedal Position relearn might be required to ensure proper brake light and traction control function. These are standard post-installation steps for many modern electronic components.
This module is a direct replacement for a wide array of original part numbers, including: 10382479, 15093910, 15276271, 15819552, 20815898, 22860591, 25892622, and many more. It fits a vast range of GM vehicles beyond the Cadillac CTS, such as the Chevy Impala, GMC Acadia, Chevy Tahoe, and GMC Savana vans. Please verify your part number to ensure compatibility.
Frequently Asked Questions
What does the BCM do on my Cadillac CTS?
The Body Control Module (BCM) acts as the brain for your car’s electronic accessories. It controls functions like power windows, locks, lights, wipers, security system, and more, ensuring they all work together seamlessly.
Do I need to program this module?
No. We handle the programming for you before shipment. Just provide your vehicle’s VIN during checkout, and the BCM will arrive flashed with the latest GM software and ready for installation.
Is this part difficult to install?
For the 2008-2013 CTS, the BCM is typically located in the left-hand (driver’s side) dash area. Installation involves disconnecting the battery, removing a few trim panels, and swapping the module. It’s manageable for a skilled DIYer, but professional installation is always recommended if you’re unsure.
What if my airbag light is on after installation?
This can happen occasionally. It means the new BCM needs to be synced with the airbag system’s Supplemental Deployment Module (SDM). A technician with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for my old part?
No, there is no core charge for this part. You can keep your original module without needing to send it back.
