Are you battling frustrating electrical gremlins in your GM truck, van, or SUV? Flickering dashboard lights, power windows with a mind of their own, or accessories that work intermittently are classic signs of a failing Body Control Module (BCM).

Expert Insight: The Dealership Alternative
As a technician, I’ve seen countless owners spend a fortune trying to diagnose individual electrical faults—a faulty switch here, a bad relay there—when the BCM was the real culprit. The dealership repair process often involves multiple visits: one for diagnosis, another to order the part, and a final one for installation and programming. Our process cuts through the complexity. By sending you a Programmed 15819552 Body Control Module ready for installation, we eliminate the programming barrier, turning a multi-day ordeal into a straightforward component swap for you or your mechanic.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that supervises and controls many of your vehicle’s non-engine-related functions. This includes power windows, power mirrors, air conditioning, the anti-theft system, central locking, and interior/exterior lighting. It’s the command center for passenger comfort and convenience features.
Why is providing my VIN so important?
Your Vehicle Identification Number (VIN) allows us to access the exact factory calibration file for your specific vehicle. We use it to program the BCM with the correct software for your trim level, options (like keyless entry, power seats, etc.), and security system. Without this step, the module would not function correctly.
Is this a simple plug-and-play installation?
Because we pre-program the unit, it is significantly easier than installing a blank module. However, in some vehicles, additional post-installation steps, known as ‘relearn procedures,’ may be required. For example, syncing the airbag system or recalibrating the brake pedal position sensor may need to be done with a professional scan tool. This is a standard part of the repair process for many modern vehicles.
How do I know my BCM is the problem?
While the symptoms listed above are strong indicators, the only way to be 100% certain is through proper diagnostics with a compatible scan tool. A professional mechanic can check for communication errors and specific BCM-related trouble codes (often starting with ‘B’ or ‘U’). This Programmed 15819552 Body Control Module is the solution once a faulty BCM has been confirmed.
What if the airbag light is on after I install the BCM?
This is a common occurrence. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A qualified technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to sync the systems and turn off the light.
