Expert Pro Tip
Expert Pro Tip
Before replacing your BCM, always perform a thorough check of the main battery ground connection to the engine block and the chassis grounds. A corroded or loose ground is a common cause of BCM failure and can damage the new unit if not corrected first. This simple check can save you from a repeat repair.
Is Your Truck Showing These Symptoms?
A faulty BCM can manifest in numerous ways that may seem unrelated. If you’re experiencing any of the following, your BCM is the likely cause:
- ✔ Erratic or non-functional power windows, door locks, or exterior/interior lights.
- ✔ Complete loss of HVAC controls or an intermittently working blower motor.
- ✔ An illuminated airbag warning light on the dash, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Security system malfunctions, causing no-start conditions, random stalling, or misfires.
- ✔ A variety of seemingly random electrical DTCs stored in the vehicle’s memory.
The Direct Solution: A Programmed Silverado 3500 Body Control Module
This isn’t just a replacement part; it’s a complete, ready-to-install solution. The BCM is the command center for your truck’s comfort and convenience features. When it fails, it can make your daily drive frustrating and unpredictable. By ordering our pre-programmed Silverado 3500 Body Control Module, you bypass the typical hassle and expense of a dealership visit. We flash the module with the latest GM software updates using your VIN, so it communicates perfectly with your truck’s other systems right out of the box.
Installation is straightforward for the average DIY mechanic, typically located under the driver’s side dashboard. While the physical swap is quick, be aware of potential post-installation procedures. If the airbag light persists, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. Similarly, a Brake Pedal Position relearn might be necessary. This module is a reliable fix for a wide range of GM trucks and SUVs, including the Sierra, Tahoe, Yukon, Suburban, and Escalade, and is interchangeable with part numbers 25835966, 15263363, 15263497, 15878753, 15943678, 20939137, and 22860591 among others.
