Restore Full Electrical Function to Your GM Vehicle
Is your 2008-2012 Chevrolet Express 1500 or another compatible GM vehicle suffering from bizarre electrical issues? Flickering lights, malfunctioning power windows, erratic dashboard warnings, or a no-start condition can often be traced back to a single, critical component: the Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, a failing BCM can create a cascade of frustrating and unpredictable problems. This replacement Body Control Module, part number 15828601, is the definitive solution to restore your vehicle’s stability and functionality.
From the Diagnostic Bay
We had a 2011 Savana work van come in that was driving the owner crazy. The dome lights would stay on, the power locks worked intermittently, and sometimes the van wouldn’t start, showing a security light on the dash. The battery and alternator tested fine. After hooking up the scan tool, we saw multiple communication loss codes with various modules. This pointed us directly to the BCM. Instead of a costly trip to the dealer, we installed one of these VIN-programmed modules. The van fired right up, all the gremlins were gone, and the customer was back on the road the same day. A failing BCM can mimic a dozen other problems, but replacing it is often the direct fix.
Is Your Body Control Module Failing?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following symptoms, it’s a strong indicator that your BCM needs replacement:
- ✔ Power windows, locks, or mirrors not working correctly or at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system acting erratically, preventing the engine from starting.
- ✔ False warnings appearing on the instrument cluster (e.g., “Service Airbag,” “Service Traction System”).
- ✔ Intermittent issues with the radio, climate control, or other accessories.
- ✔ Complete loss of communication with the scan tool, or multiple communication error codes.
- ✔ Parasitic battery drain that leaves you with a dead battery overnight.

Important Post-Installation Information
While our VIN programming handles the majority of the setup, certain vehicle systems may require a relearn procedure after the new BCM is installed. These are standard procedures for this type of repair and can typically be performed by a qualified technician with a professional-grade scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary to ensure proper operation of the brake lights and stability control systems.
Please consult a factory service manual or a professional mechanic for detailed instructions specific to your vehicle’s make and model.
Frequently Asked Questions
Do I need to send you my VIN?
Yes, providing your Vehicle Identification Number (VIN) is mandatory. We use your VIN to program the module with the correct software and vehicle options from GM’s database, ensuring compatibility and proper function.
Is this a difficult part to install?
The physical installation is typically straightforward, involving disconnecting the battery and swapping the module. However, some post-installation relearn procedures, like for the airbag or brake systems, may require a professional scan tool. The location of the BCM varies by model, so we recommend consulting a repair manual.
Will this fix my vehicle’s security system issue?
In most cases, yes. A failing BCM is a very common cause of security system faults and no-start conditions on these GM vehicles. Our VIN programming correctly sets up the anti-theft parameters to match your existing keys.
Is there a core charge for my old BCM?
No, there is no core charge for this part. You can keep your original module without needing to send it back to us.
What if I have an airbag light on after installation?
An airbag light is a common occurrence after a BCM replacement. It simply means the new BCM needs to be electronically introduced to the airbag module. A technician with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
