Restore Full Functionality to Your Vehicle’s Electronics
If you’re dealing with baffling electrical issues in your 2011-2013 Chevrolet Caprice—like power windows that have a mind of their own, door locks that won’t respond, or a security light that prevents your car from starting—you’ve likely pinpointed the culprit: a failing Body Control Module (BCM).

Simply provide your vehicle’s VIN during checkout, and our technicians will load the latest, most stable GM software specific to your Caprice. This ensures seamless integration and restores all functions as the factory intended. This is the most efficient way to get your vehicle back to 100% without hidden fees or complex procedures.
From the Diagnostic Bay
I remember a 2012 Caprice PPV that came into the shop. The department was ready to sideline it. The radio would turn on and off, the interior lights flickered randomly, and sometimes it just wouldn’t crank. Multiple techs had chased wires, suspecting a short. After hooking up my scan tool, I saw a slew of U-codes (communication errors) pointing to the BCM. Instead of a wild goose chase, we swapped in a pre-programmed BCM like this one. In under an hour, every single gremlin was gone. It’s a classic case where replacing the brain is simpler than trying to fix every nerve ending.
A Straightforward Guide to BCM Installation
Installing your new 2011-2013 Caprice BCM is a manageable job for a DIY enthusiast. The BCM is typically located behind the driver’s side of the dashboard. Follow these general steps for a successful replacement.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait about 10-15 minutes to allow all systems to power down completely.
- Locate the BCM: On the Caprice, you’ll typically find the BCM mounted on the driver’s side, often to the left of the steering column or behind the lower dash panel. You may need to remove a trim panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be pressed to release. Once all connectors are free, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely plug in all the electrical connectors, ensuring each one clicks firmly into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test your electronics: power windows, locks, lights, and radio.
- Perform Relearns (If Needed): Start the vehicle. If an airbag light or brake system warning appears, you may need to perform the specific relearn procedures noted in our post-installation section using a compatible scan tool.
Is Your Caprice BCM Failing?
A failing Body Control Module can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your BCM needs attention. Look out for Diagnostic Trouble Codes (DTCs) like U0140, B1001, or other communication and configuration errors.
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔ Interior or exterior lights staying on or not turning on.
- ✔ The anti-theft or security system light is illuminated, causing a no-start condition.
- ✔ The horn honking unexpectedly or not working when pressed.
- ✔ Inaccurate or non-functional gauges on the instrument cluster.
- ✔ False warnings appearing on the driver information center (e.g., ‘Service Theft System’).
- ✔ Communication errors with other modules when checked with a scan tool.

Do I need to do any programming after I receive this BCM?
Do I need to do any programming after I receive this BCM?
No. We program the module to your vehicle’s VIN before shipping. It arrives ready to be installed. However, some vehicles may require a simple ‘relearn’ procedure for the brake pedal position sensor or airbag system, which can sometimes be done with a high-end bidirectional scan tool.
What is a VIN and where do I find it?
The VIN (Vehicle Identification Number) is your car’s unique 17-digit serial number. You can find it on a plate on the driver’s side of the dashboard (viewable through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
Is there a core charge or do I need to send my old part back?
No, there is absolutely no core charge for this part. You can keep your old module, which is helpful if you ever need to reference its part number or have it for any other reason.
What happens if the airbag light is on after installation?
If the airbag (SRS) warning light appears, it means the new BCM needs to be synced with the airbag’s SDM (Sensing and Diagnostic Module). A procedure called ‘Setup SDM Primary Key in BCM’ needs to be performed with a professional-grade scan tool to resolve this.
Will this fix my ‘Service Theft System’ message?
In many cases, yes. The BCM is integral to the Pass-Key III+ or Passlock anti-theft systems. A failing BCM is a very common cause of this message and the associated no-start condition. Our programming ensures the security data matches your vehicle’s key and ignition.
