Are you battling a storm of strange electrical problems in your GMC Yukon, Chevy Silverado, or Cadillac Escalade? Intermittent power windows, a malfunctioning HVAC system, flickering lights, or a persistent airbag warning light are common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics. When it malfunctions, it can create frustrating and difficult-to-diagnose issues. This genuine GM BCM, part number 25844480, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play repair.
Common Symptoms of a Failing BCM

- ✔ Vehicle security system malfunctions, causing false alarms or starting issues.
- ✔ An active airbag warning light, often with DTC B1001.

Installation and Post-Install Procedures
The BCM is typically located under the driver’s side dashboard, near the steering column, making for a straightforward replacement that often takes less than 15 minutes. While the installation is plug-and-play for most functions, be aware of these potential post-installation steps:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool and syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure correct brake light operation and traction control functionality.
Note: There is no core charge for this part. You can keep your old module without any hassle.
