Restore Full Functionality to Your GM Truck
Are you battling bizarre electrical issues in your 2013 Silverado 2500? Flickering lights, a dead HVAC blower, or power windows with a mind of their own are classic signs of a failing Body Control Module (BCM). As the electronic nerve center for your truck’s comfort and convenience features, a faulty BCM can cause a cascade of frustrating problems. This OEM-quality replacement, part number 15284816, is the definitive solution. We pre-program it to your vehicle’s specific VIN, ensuring it works perfectly right out of the box, with no expensive dealership programming required. Get your truck’s essential systems—from door locks and security to wipers and lighting—working reliably again.
A Technician’s Notebook: The Ghost in the Machine
Just last month, a 2013 Silverado 2500 was towed into my bay. The owner was at his wit’s end. The radio would randomly shut off, the airbag light was on, and the driver’s side power window worked intermittently. He’d already replaced the battery and checked fuses. A quick scan showed a flurry of communication codes and a persistent DTC B1001 (Option Configuration Error). In my 20+ years of experience, these scattered, unrelated electrical symptoms almost always point to one culprit: the BCM. After confirming the grounds were solid, we installed one of our VIN-programmed modules. The electrical chaos stopped instantly, and after performing the SDM key relearn, the B1001 code cleared for good. It’s a common failure, but with the right part, it’s a straightforward fix.
Is Your Truck Showing These Symptoms?
- ✔ Airbag warning light is on, often with DTC B1001.
- ✔ HVAC controls are unresponsive, or the blower motor works only on high or not at all.
- ✔ Power windows, door locks, or interior/exterior lights operate erratically or have failed completely.
- ✔ The anti-theft or security system malfunctions, causing no-start or stalling conditions.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ A flood of communication codes (U-codes) or other body-related DTCs are present.
A Straightforward Guide to Your BCM Replacement
Replacing the BCM is a job most DIYers can handle in minutes. The key is the post-installation procedure to ensure all systems communicate correctly.
- Safety First: Always disconnect the negative terminal from your truck’s battery before starting any electrical work.
- Locate the Module: The BCM is typically found under the driver’s side dashboard, near the steering column. It’s a black box with several large multi-pin connectors.
- Swap the Part: Carefully unplug the electrical connectors from the old BCM. Unbolt or unclip the module from its mounting bracket and remove it. Install the new module and securely re-attach all connectors.
- Reconnect Power: Re-attach the negative battery terminal.
- Critical Relearn Procedures: This is the most important step. After installation, an airbag light will likely be present. You must use a bi-directional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. Some vehicles may also require a Brake Pedal Position Sensor recalibration. These steps ensure the safety systems are fully operational.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like your lights, power windows and locks, wipers, climate control, and security system.
Is this BCM really ‘plug-and-play’?
Yes, the physical installation is plug-and-play. Because we program it to your VIN before shipping, it has the correct software for your vehicle’s options, avoiding a trip to the dealer for programming. However, you will need a scan tool for post-installation safety system relearns.
Why is my airbag light still on after installation?
This is normal. The new BCM needs to be electronically ‘introduced’ to the vehicle’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure using a capable bi-directional scan tool to clear the light and ensure the system is active.
What tools do I need for this job?
You’ll need basic hand tools like a socket set to disconnect the battery and remove the BCM mounting bolts. The most critical tool is a bi-directional scanner capable of performing the SDM relearn procedure.
Is there a core charge for my old part?
No, there is no core charge. You can keep or dispose of your old module without the hassle of sending it back.
