Is your Silverado, Sierra, or Tahoe suffering from strange electrical problems?
If your power windows have a mind of their own, your door locks aren’t responding, or your dashboard is lit up with warning lights, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your truck’s body electronics, managing everything from the interior lights and HVAC system to the security features. When it fails, it can cause a cascade of frustrating and seemingly unrelated issues. This genuine GM Body Control Module, interchangeable with part number 25823558, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ HVAC controls are unresponsive, or the blower motor works sporadically.
- ✔ The security system malfunctions, causing no-start conditions or false alarms.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) fail to work correctly.
- ✔ The airbag warning light is illuminated, often with a DTC B1001 code stored.
- ✔ Unexplained battery drain when the vehicle is turned off.

Installation and Post-Install Procedures
Physically installing the BCM is straightforward. It’s typically located under the driver’s side dashboard, near the steering column, and can be swapped in minutes. However, after installation, some vehicles may require additional electronic steps:
- Airbag System Sync: If the airbag warning light remains on 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 relearn may be needed to ensure correct brake light operation and traction control function.

Frequently Asked Questions
What does ‘VIN Programmed’ mean for me?
It means we pre-load the module with your truck’s specific software before shipping it. This makes the installation plug-and-play, saving you from a mandatory and costly programming session at a GM dealership.
Is this BCM difficult to install myself?
The physical replacement is very simple, usually taking less than 15 minutes with basic tools. It’s located under the steering column. However, be aware that post-installation electronic procedures, like an airbag system sync, may require a professional scan tool.
My airbag light is on after installing the new BCM. Is the part defective?
No, this is a normal security procedure on GM vehicles. The new BCM needs to be electronically introduced to the airbag system (SDM). A mechanic with an advanced scan tool can perform the ‘Setup SDM Primary Key in BCM’ function to resolve this.
Will this fit my 2009 GMC Sierra 1500?
Yes, this BCM fits a wide range of 2007-2013 GM trucks and SUVs, including the GMC Sierra, Chevrolet Tahoe, Cadillac Escalade, and more. Please check the detailed fitment list on this page to confirm compatibility with your exact model.
Do I need to return my old BCM?
