Restore Your Vehicle’s Electrical System with a Reliable, Programmed BCM
Are you dealing with baffling electrical issues in your Chevrolet Cruze or other GM vehicle? Intermittent power windows, flickering dashboard lights, a security system that acts up, or even a car that refuses to start can often be traced back to a single component: a failing Body Control Module (BCM). As the central hub for your car’s body electronics, its failure can create a cascade of frustrating problems. This isn’t just an inconvenience; it can be a significant safety concern. I’ve spent over two decades diagnosing these exact issues, and I can tell you that a faulty BCM is one of the most common culprits for electronic gremlins that seem to have no other explanation.
Case Study: A Tricky Diagnosis
A customer brought in their 2013 Chevy Cruze with a complaint that was driving them crazy. The radio would turn on and off by itself, the turn signals worked only sometimes, and occasionally, the car wouldn’t recognize the key fob. They had already replaced the battery and checked all the fuses. After connecting my scan tool, I found multiple ‘Loss of Communication’ codes (U-codes) with various modules. This pointed directly to the network’s traffic controller—the BCM. Instead of a costly trip to the dealer for a new module and programming, we used our cloning service. We transferred the data from their original, failing BCM to one of our reliable replacement units. The customer had their car back the next day with all electrical issues resolved, saving them hundreds of dollars and a lot of headaches. This is the simple, effective solution we offer you.
How Our Simple Cloning Service Works
Forget about expensive dealership programming fees and the hassle of getting your vehicle towed. Our service is designed to be a straightforward, plug-and-play solution. Here’s the process:
- You purchase this BCM service.
- We will contact you with clear instructions for shipping your original BCM to our facility.
- Once we receive your module, our expert technicians will transfer all the critical data (including VIN, key information, and vehicle-specific settings) to this replacement unit.
- We ship the fully programmed, ready-to-install BCM back to you, typically within one business day.
This process ensures that the replacement module is a perfect electronic match for your vehicle, making installation as simple as swapping the part. Plus, there is no core charge, so you can keep your original module.
Common Signs of a Failing BCM
- ✔ Power windows, door locks, or interior lights operating erratically or not at all.
- ✔ The security or anti-theft light stays on, preventing the car from starting.
- ✔ Windshield wipers or turn signals behaving unpredictably.
- ✔ Dashboard warning lights illuminating for no reason.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0100, U0140, or other U-codes.
- ✔ Horn, radio, or climate control malfunctions.
Your Straightforward BCM Installation Guide
Installing your programmed 2013 Cruze BCM is a manageable task for a DIY enthusiast or any professional mechanic. The BCM is typically located in the driver’s side footwell or behind the kick panel.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On a 2013 Cruze, you’ll find it behind the driver’s side kick panel, near the fuse box. 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. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount the replacement BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Test Functionality: Start the vehicle and test all body functions—lights, windows, locks, wipers, and radio—to confirm the repair was successful.
Important Post-Installation Information
In most cases, this module is a true plug-and-play solution. However, on some GM models, additional steps may be required:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: Some vehicles may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
What exactly is a ‘cloning’ service?
Cloning is the process of reading the essential vehicle-specific data (like VIN, mileage, and security information) from your original BCM and writing it onto the replacement module. This makes the new part electronically identical to your old one, allowing you to avoid a costly and complicated programming procedure at a dealership.
Is this difficult to install myself?
For someone with basic mechanical skills, the installation is very straightforward. The main task is accessing the BCM (usually behind a kick panel), disconnecting the old one, and plugging in the new one. Our cloning service handles all the complex programming, so you don’t need any special computers or software.
Do I need to send my keys with my BCM?
No, you do not need to send us your keys. All the necessary key data is stored within your original BCM, and we will transfer it directly to the replacement unit. Your existing keys will work seamlessly upon installation.
How long does the programming service take?
We pride ourselves on a fast turnaround. Once we receive your original BCM, we typically complete the cloning and ship your ready-to-install module back to you within one business day.
What if the airbag light comes on after I install the new BCM?
This is uncommon, but if it happens, it means the BCM and the airbag’s Sensing and Diagnostic Module (SDM) need to be electronically re-synced. This procedure, called ‘Setup SDM Primary Key in BCM,’ must be done with a professional-grade scan tool but is a quick process for any competent repair shop.
Will this programmed 2013 Cruze BCM fix my specific problem?
If your vehicle’s symptoms match the common signs of BCM failure and your mechanic has diagnosed the BCM as the faulty component, this part is the correct solution. It is designed to restore all functions controlled by the Body Control Module.
