This OEM-quality replacement, equivalent to part number 22860591, arrives fully programmed to your vehicle’s specific VIN.

A Technician’s Notebook: The Ghost in the Machine
I remember a 2010 Silverado 2500 that came into my shop with a laundry list of complaints. The radio would turn on and off, the driver’s side power lock was dead, and the airbag light was on with a DTC B1001. The owner had already replaced the lock actuator and checked fuses, but the problems persisted. After confirming the main grounds were solid, we hooked up the scanner. The BCM was failing to communicate intermittently with other modules. Instead of a multi-day diagnostic nightmare, we installed a VIN-programmed BCM. In under an hour, every single electrical gremlin was gone. This is a classic case where the BCM is the central point of failure for seemingly unrelated issues.
Is Your Silverado Showing These Electrical Warning Signs?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Unresponsive or erratic HVAC controls, including a blower motor that won’t turn on or off.
- ✔ Power windows, door locks, or interior/exterior lights that work intermittently or not at all.
- ✔ An active airbag warning light on the dash, often accompanied by diagnostic trouble code B1001.
- ✔ Security system malfunctions, causing no-start conditions or random alarm activation.
- ✔ Strange electrical behavior, such as the radio turning off, wipers activating on their own, or communication errors between modules.
Your 5-Minute BCM Installation Guide
Replacing the BCM on your Silverado is a straightforward job that most DIYers can handle in their own driveway. Our VIN programming makes it a true plug-and-play process.
- Safety First: Always disconnect the negative terminal from your truck’s battery to prevent any electrical shorts.
- 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 electrical connectors.
- Swap the Part: Carefully unplug the wiring harnesses from the old BCM. Unbolt or unclip the module from its mounting bracket and remove it. Install the new module in its place and securely reconnect all wiring harnesses.
- Reconnect and Test: Reconnect the negative battery terminal. Start your truck and test all functions: lights, locks, windows, wipers, and HVAC system to confirm the repair.
Post-Installation Note: In some cases, special procedures may be needed. If the airbag light remains on, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ function. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary. There is no core charge for this part, so you can keep or discard your old module without any hassle.

Frequently Asked Questions
What does a Body Control Module do on a Silverado 3500?
The BCM acts as the brain for your truck’s cabin and body electronics. It controls non-engine related functions like your lights, power windows and locks, security system, wipers, and climate control system.
Is this 2007-2011 Silverado 3500 BCM difficult to install?
No, installation is very simple for most DIYers. It’s located under the dash and involves unplugging the old module and plugging in the new one. Since we program it to your VIN, no further dealership programming is required for basic functions.
Do I need to send my old BCM back?
No, there is absolutely no core charge or return required. You can keep your old part.
My airbag light is still on after installing the new BCM. What should I do?
This is a known GM security feature. You will need a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system (SDM) and will turn off the light.
Will this fix my check engine light?
Generally, no. The BCM controls body functions, while the Engine Control Module (ECM) or Powertrain Control Module (PCM) manages the engine and transmission. If you have a check engine light, you likely need to diagnose a different component.
