Restore Your Vehicle’s Electrical System with Confidence
Are you battling bizarre and unpredictable electrical problems in your GM vehicle? Flickering dashboard lights, power windows with a mind of their own, a security system that won’t cooperate, or even a no-start condition can all point to a single, critical component: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, a faulty BCM can cause widespread chaos. This Programmed 15948439 Body Control Module is the definitive, hassle-free solution to get your vehicle back in perfect working order.
Common Symptoms & Your Solution
If your GM truck, van, or SUV is experiencing any of the following issues, a failing BCM is the likely culprit:
- Intermittent or non-functional power windows, door locks, and interior lights.
- Erratic instrument cluster behavior or warning lights that come on for no reason.
- Problems with the anti-theft or keyless entry systems.
- HVAC (heating and air conditioning) control issues.
- Communication errors with other vehicle modules (DTC U-codes).
Instead of spending a fortune at the dealership on diagnostics and programming fees, this module arrives at your door ready for installation. We use your vehicle’s VIN to flash the BCM with the latest, most stable software updates from GM, ensuring it integrates seamlessly with your specific vehicle’s options and systems.

Expert Insight: The Diagnostic Time-Saver
“As a technician, I’ve seen countless hours and dollars wasted chasing electrical gremlins. A mechanic might replace a window motor, then a switch, only to find the problem is still there. That’s because the BCM is the ‘brain’ giving the commands. A failing BCM can send faulty signals, making good parts appear broken. By starting with a properly Programmed 15948439 Body Control Module, you’re not just replacing a part; you’re restoring the command center of your vehicle’s electronics, often fixing multiple, seemingly unrelated issues at once and saving a fortune in diagnostic guesswork.”
Frequently Asked Questions
Do I need to do any programming after I install this BCM?
No. We handle all the primary programming based on the VIN you provide during checkout. This makes the installation process as simple as possible. However, for some vehicles, certain minor relearn procedures, like for the brake pedal position sensor or airbag system, may be required. These can often be done with a high-level scan tool.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. Please double-check the VIN for accuracy to ensure perfect compatibility.
What if my original part number is not 15948439?
This module is a direct replacement for a long list of original GM part numbers, which are listed in the product details. As long as your vehicle model and year are listed and your original part number is on our cross-reference list, this module will work perfectly for you.
What is the ‘Setup SDM Primary Key in BCM’ procedure?
This is a specific relearn procedure that may be needed if your airbag light comes on after installation. It syncs the new BCM with the vehicle’s existing airbag control module (SDM). This procedure requires a professional-grade diagnostic tool and is only necessary if the airbag warning light is illuminated.
Is this a difficult part to install myself?
For someone with moderate mechanical experience, the installation is very manageable. The BCM is typically located under the dashboard on the driver’s or passenger’s side. The most important steps are to disconnect the vehicle’s battery before you begin and to carefully transfer all electrical connectors to the new module. Always consult a service manual for your specific vehicle’s location and procedure.
