Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you battling a storm of bizarre electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or a car that refuses to start can all point to one culprit: a failing Body Control Module (BCM). In my 20+ years of automotive diagnostics, I’ve seen how a faulty BCM can turn a reliable vehicle into a source of daily frustration. The dealership solution often involves a brand-new module, expensive programming fees, and a significant amount of your time. We offer a smarter, more efficient path back to reliability.
This is a comprehensive programming service for a replacement BCM. You simply send us your vehicle’s original module. Our expert technicians will then transfer all the critical data—including VIN, mileage, and key information—to this fully tested replacement unit. We ship it back to you, ready for installation. This process ensures a seamless, plug-and-play experience, eliminating the need for any additional programming or key relearning at a dealership. It’s the most direct way to get your car back to 100% functionality.
A Technician’s Notebook: The Case of the Confused Cruze
A 2014 Chevy Cruze came into my bay with a laundry list of complaints from the owner: the radio would turn on and off, the turn signals worked intermittently, and the anti-theft light would flash, preventing it from starting. The owner had already replaced the battery, but the problems persisted. A quick scan revealed a slew of communication error codes (U-codes) pointing to the BCM. Instead of a costly replacement and programming at the dealer, we used this exact cloning service. By transferring the data from the original, failing BCM to a good replacement, we had the car fixed in a day, saving the customer hundreds of dollars and the headache of a dealership visit. This is a common story for this family of GM BCMs.
Common Signs of a Failing GM BCM
If your vehicle is experiencing any of the following, a faulty BCM could be the root cause. Look out for Diagnostic Trouble Codes (DTCs) like U0140, U0155, or B1001.
- ✔ Unpredictable instrument cluster behavior (gauges dropping, warning lights on)
- ✔ Power windows, locks, or interior lights not working correctly
- ✔ Vehicle’s security system engaging randomly, causing a no-start condition
- ✔ Inconsistent operation of headlights, taillights, or turn signals
- ✔ Communication errors with other modules on the vehicle’s network
- ✔ Key fobs that suddenly stop working
Your Straightforward BCM Installation Guide
Installing your programmed BCM is a manageable task. The location varies by model, so confirm it for your specific vehicle before starting. For the 2013 Volt, it’s typically in the right-hand side of the engine compartment.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: Find the original BCM. Common locations include behind the driver-side kick panel, under the dash, or in the engine bay.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your newly programmed BCM in the same location. Reconnect all electrical connectors securely, ensuring they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Test Functionality: Start the vehicle and test all body-related functions—windows, locks, lights, wipers, etc.—to confirm the repair. Note the post-installation procedures below.
Important Post-Installation Information
While our programming handles the core functions, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This is only needed if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
Disclaimer: Always consult a factory service manual or a certified technician for procedures specific to your vehicle.

Frequently Asked Questions
How does the programming service work?
After you place your order, we’ll contact you with instructions to ship your original BCM to us. Once we receive it, we transfer its data to the replacement module and ship the ready-to-install part back to you, typically within 1-2 business days.
Will I need to get my keys reprogrammed?
No. Because we clone the data from your original module, the replacement BCM will recognize your existing keys. This is a major benefit that saves you time and money.
Is this a reliable fix for my 2013 Volt Body Control Module?
Absolutely. We use a fully tested, functioning BCM and transfer your vehicle’s specific data. This restores original functionality and is a durable, long-term solution to common BCM failure symptoms.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is not functioning in the vehicle, we can still extract the necessary data for the cloning process. Please contact us with your specific situation if you have concerns.
Do I need to send my old BCM back after I install the new one?
No, there is no core charge for this service. You only need to send us your original BCM for the initial programming service. You can keep your old module afterward.
What tools are required for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a bi-directional professional diagnostic tool (like a Snap-on, Autel, or GM Tech 2). Most professional repair shops have this equipment.
