Restore Full Functionality to Your GM Vehicle
If you’re dealing with baffling electrical issues in your 2008-2012 Express 3500 Van—like power windows with a mind of their own, intermittent starting problems, or a security light that won’t turn off—a failing Body Control Module (BCM) is the likely culprit. As the central hub for your vehicle’s body electronics, a faulty BCM can cause widespread and frustrating problems. This replacement Body Control Module, part number 15828601, is the reliable, straightforward solution to get your work van or family hauler back in perfect working order without the exorbitant costs and delays of a dealership visit.
We take the guesswork and hassle out of the repair. Simply provide your vehicle’s VIN after purchase, and our expert technicians will program the module with the latest GM software specifically for your vehicle. It arrives at your door ready for installation, eliminating the need for expensive scan tools or programming appointments. This is the most efficient way to solve those electrical gremlins for good.
From the Diagnostic Bay: The Case of the Finicky Express Van
A contractor brought his 2011 Express 3500 into my shop, completely fed up. His dome lights would stay on, draining the battery overnight, and the power door locks worked only when they felt like it. He’d already replaced the battery and checked all the fuses. A quick scan showed multiple U-codes (communication errors) pointing to the BCM. These modules, especially in hard-working vans, often fail from years of thermal stress and vibration. We installed one of our pre-programmed BCMs, and in under an hour, every single issue was resolved. He was back on the job site the same day, saving himself a tow to the dealer and hundreds in diagnostic and programming fees. This is a common story, and a quality, correctly programmed 2008-2012 Express 3500 BCM is almost always the fix.
Is Your GM Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is your solution:
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system light is on, or the vehicle won’t start due to a false theft alert.
- ✔ Horn honking unexpectedly or not working.
- ✔ The radio or instrument cluster behaves erratically.
- ✔ Communication DTCs like U0140, U0155, or other related codes.
A Straightforward Guide to Installation
Replacing the BCM is a manageable job for a DIYer or any professional technician. While the exact location can vary slightly, here is a general guide for a 2008-2012 Express 3500 BCM.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On most Express and Savana vans, the BCM is located behind the center dash panel, often near the junction block. You may need to remove a few trim pieces for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all electrical connectors, ensuring they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, locks, windows, horn, etc.—to confirm the repair was successful.
- Post-Installation Checks: In some cases, an Airbag light or Brake light may appear. This is normal and requires a simple sync procedure (see our FAQ). Always consult a service manual for your specific model if you are unsure.

Frequently Asked Questions
How does the VIN programming service work?
How does the VIN programming service work?
It’s simple. After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). Our technicians use this to load the precise factory software and vehicle-specific options into the BCM. It arrives ready to install with no additional programming required.
Do I need to send my old BCM back?
No, this is a cloning service, which means we use your VIN to program a replacement module. We ship the programmed replacement to you, and your original module is always returned to you along with it. We do not keep your original part.
What tools are needed for the post-installation procedures?
In most cases, no special tools are needed. However, if the airbag (SRS) light comes on, a professional-grade scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems. Similarly, a Brake Pedal Position relearn may be needed, which can also be done with a capable scan tool.
Is this a guaranteed fix for my vehicle’s electrical problems?
While this 2008-2012 Express 3500 BCM is the solution for the vast majority of the symptoms listed, proper vehicle diagnosis is key. We recommend confirming the BCM is the point of failure before ordering. Common signs include multiple unrelated electrical faults and specific communication error codes.
Will this BCM work for a different vehicle if it’s on the fitment list?
Yes, this module fits a wide variety of GM cars, trucks, and SUVs. However, the programming is vehicle-specific. When you provide your VIN, we will ensure it is programmed correctly for your exact make, model, and options, whether it’s an Impala, Acadia, or Savana van.
