Tired of Chasing Electrical Gremlins in Your GM Truck?
If you’re a 2007-2011 Silverado 1500 owner, you know it’s a dependable workhorse. But when the electronics start acting up—lights flickering, locks misbehaving, or strange warning lights appearing on the dash—it can be incredibly frustrating. After 20+ years of hands-on diagnostics, I’ve seen these exact issues countless times. More often than not, the culprit is a failing Body Control Module (BCM), the central command center for your truck’s body electronics.
Instead of paying for expensive dealership diagnostics and programming fees, we offer a straightforward, reliable solution. This replacement Body Control Module, compatible with part number 15901388, is prepared for your truck using our professional Cloning Service. We transfer the critical data from your original BCM to this replacement unit, making it a true plug-and-play fix. No trips to the dealer, no complex programming tools needed. You get a part that works right out of the box, restoring your truck’s functionality and your peace of mind.
A Technician’s Notebook: The Grounding Gremlin
I once had a 2009 Sierra in the bay that was driving the owner crazy. The radio would cut out, the dash lights would flicker when hitting a bump, and he was getting a random airbag light. He’d already replaced the battery and alternator. After checking the schematics, I went straight for the BCM. The module itself tested okay, but a quick check of the main BCM ground point under the dash revealed corrosion. This weak ground was causing voltage drops that mimicked a complete BCM failure. We cleaned the ground, but the intermittent stress had already damaged the module internally. A cloned BCM and a clean ground point had the truck running perfectly. Lesson: When you replace your BCM, always inspect and clean the ground connections! It’s a 5-minute step that prevents a world of headaches.
Is Your Silverado Showing These Symptoms?
A failing BCM can cause a wide range of confusing electrical problems. If your truck is experiencing any of the following, a replacement is likely the solution:
- âś” Unresponsive or erratic power windows, door locks, or mirrors.
- âś” Interior or exterior lights that don’t work, stay on, or flicker randomly.
- âś” An airbag warning light on the dash, often with Diagnostic Trouble Code (DTC) B1001.
- âś” HVAC system problems, such as a blower motor that won’t turn on or fan speed that can’t be controlled.
- âś” Malfunctioning security system, leading to no-start conditions or random alarm activation.
- âś” Wipers operating intermittently or not parking in the correct position.
A Straightforward Guide to Installation
The physical installation is simple and can be done with basic hand tools in your own garage. Our cloning service handles the complicated part—the programming.
- Step 1: Send Us Your Original BCM. After placing your order, you’ll ship your original module to us. This is essential for the cloning process. We return your original module with your newly prepared replacement.
- Step 2: Disconnect the Battery. Before starting any electrical work, always disconnect the negative battery terminal to prevent shorts.
- Step 3: Locate and Remove the Old BCM. The BCM is typically located under the driver’s side dashboard, near the steering column. It’s held in place by a few clips or small bolts. Carefully disconnect the electrical connectors.
- Step 4: Install the New BCM. Connect the electrical harnesses to your new, cloned module and secure it in the mounting bracket. Reconnect the battery.
- Step 5: Perform Post-Install Checks. Start the vehicle and test all functions (lights, locks, windows, etc.). If your airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. Some models may also require a ‘Brake Pedal Position Relearn’.

Frequently Asked Questions
Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is a process where we read the unique, vehicle-specific software and security data from your original BCM and write it directly onto the replacement module. This makes the new part an exact digital copy, ensuring it communicates perfectly with your truck’s other systems without needing dealer programming.
Do I have to send my original module in first?
Yes. For the cloning service to work, we need your original BCM to extract its data. We will return your original module along with the fully programmed replacement unit. We do not keep your old part.
Will this fix my airbag light and code B1001?
Replacing a faulty BCM is often the correct fix for a B1001 code. However, after installation, the security link between the BCM and the airbag system (SDM) must be re-established. This requires a ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade scan tool.
Is this part difficult to install for a DIYer?
The physical swap is very easy for most DIYers and takes just a few minutes with basic tools. The main challenge can be the post-installation electronic procedures, like the airbag sync. If you don’t have an advanced scan tool, a local mechanic can perform these relearns for you.
What if my windows or locks still don’t work correctly after installation?
First, double-check all connector plugs are seated firmly. Second, inspect the related fuses. Since our cloning process transfers your vehicle’s exact configuration, a persistent issue may point to a problem with a different component, like a window motor or a wiring fault, not the BCM itself.
