Tired of Chasing Electrical Gremlins in Your GM Vehicle?
As a technician with over two decades of experience under the hood, I’ve seen it all. Flickering lights, power windows with a mind of their own, a security light that won’t turn off, or a car that refuses to start for no apparent reason. These baffling electrical issues often point to one culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features, and when it starts to go, it can cause a cascade of frustrating problems. This isn’t just an inconvenience; it can affect your vehicle’s security and safety.
Instead of paying for expensive dealership diagnostics and programming fees, you can get a reliable, cost-effective solution right here. We provide a high-quality replacement GM Body Control Module 15828601 that arrives at your door pre-programmed with the latest GM software, specifically matched to your vehicle’s VIN. This eliminates the most difficult part of the job, allowing for a much simpler installation process.
Case Study: A Tricky Diagnosis
I remember a 2010 GMC Yukon that came into my shop. The owner was at his wit’s end. The interior lights would flicker randomly, the radio would shut off, and occasionally the door locks would cycle while driving. Another shop had already replaced the alternator and battery to no avail. After connecting my scan tool, I noticed several U-codes (communication loss) with various modules. This is a classic sign. The issue wasn’t the individual components; it was the central hub—the BCM—that was failing to communicate properly. We installed a VIN-programmed BCM like this one, and within an hour, every single electrical issue was resolved. The customer was thrilled to have his truck back to normal without a massive dealership bill.
Is Your GM Vehicle Exhibiting These BCM Failure Signs?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your Body Control Module needs attention:
- ✔ Erratic or non-functional power windows, door locks, or interior/exterior lights.
- ✔ The security or anti-theft system light stays on, preventing the engine from starting.
- ✔ The horn honks unexpectedly or doesn’t work at all.
- ✔ Wipers operate intermittently or get stuck in one position.
- ✔ Multiple unrelated warning lights appear on the instrument cluster.
- ✔ Common diagnostic trouble codes (DTCs) like U0140, U0155, or other communication codes are present.
Your Straightforward BCM Installation Guide
With our pre-programmed module, you skip the hardest step. While the exact location varies by model (check your service manual), the general process is very manageable for a confident DIYer.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before starting work.
- Locate the BCM: On most of these GM vehicles, the BCM is located under the driver’s side dash, near the steering column or behind a kick panel. On vans, it’s often in the center dash area.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old BCM and remove it.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical harnesses. Ensure they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Relearns (If Needed): Start the vehicle. In some cases, you may need to perform a Brake Pedal Position Relearn or an Airbag System Sync as detailed in the post-install notes. This may require a bi-directional scan tool.

Frequently Asked Questions
Frequently Asked Questions
Do I need to send my old BCM back?
No, there is no core charge for this module. You can keep your original part.
Is this really plug-and-play?
Since we program the module to your VIN, it is designed for a straightforward installation without needing a trip to the dealer for software flashing. However, as noted, some vehicles may require additional ‘relearn’ procedures for systems like the airbag or brake pedal position sensor after installation.
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We cannot program and ship the module without it. This ensures we match the software perfectly to your vehicle’s specific options.
What happens if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fix my ‘Service Theft System’ message?
In many cases, a faulty BCM is the root cause of anti-theft system errors. Replacing it with a correctly programmed module is a very common and effective fix for this issue.
