Restore Full Electrical Function to Your Vehicle
Are you battling bizarre electrical issues in your Chevy Cruze or another compatible GM vehicle? Flickering lights, a horn that won’t stop, power windows with a mind of their own, or a car that refuses to start are classic signs of a failing Body Control Module (BCM). As the central hub for your car’s body electronics, a faulty BCM can turn your daily drive into a frustrating ordeal. This isn’t just an inconvenience; it can affect safety systems like your lights and security. We offer a simple, reliable solution to get your vehicle back to normal without the hefty price tag and programming headaches at the dealership.
This is a complete, pre-programmed 2011 Cruze BCM replacement service. The process is straightforward: you purchase this module, send us your original BCM, and we transfer all the critical vehicle-specific data—like key information and security settings—to this replacement unit. We then ship the ready-to-install module back to you. This cloning service means you can bypass expensive dealer programming and get a true plug-and-play fix.
A Technician’s Notebook: The Cruze with a Ghost
A few months back, a 2011 Chevy Cruze was towed into my bay. The owner was at his wit’s end. The car would randomly refuse to start, the radio would shut off, and the security light was always on. He’d already replaced the battery and checked the alternator. After connecting my scan tool, I saw a storm of communication error codes (U-codes) pointing to the BCM. Instead of just selling him a blank module that would require a tow to the dealer for programming, we performed a cloning service just like this one. Once the programmed BCM was installed, every single issue vanished. It’s a common failure, and this service is the most efficient fix I’ve found in 20+ years of diagnostics.
Common Signs of a Failing BCM
If your vehicle is experiencing any of the following, a faulty BCM is the likely culprit. A failing module can often set diagnostic trouble codes like U0140, U0155, or B1001.
- ✔ Unpredictable starting problems or a complete no-start condition.
- ✔ Power windows, door locks, or interior lights operating erratically or not at all.
- ✔ The security system light stays illuminated, preventing the car from starting.
- ✔ Horn blaring unexpectedly or not working when needed.
- ✔ Dashboard warning lights (like ABS or Airbag) coming on for no reason.
- ✔ Rapid battery drain while the vehicle is off.
A Straightforward Guide to Installation
Installing your pre-programmed BCM is a simple process that most DIY enthusiasts can handle. On a 2011 Cruze, the BCM is typically located in the driver’s side kick panel.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: Remove the driver’s side kick panel (the plastic trim piece by the driver’s left foot) to access the module.
- Disconnect the Connectors: Carefully release the locking tabs on the electrical connectors and unplug them from the old BCM.
- Remove the Old Module: Unbolt or unclip the original BCM from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely plug in all the electrical connectors.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions—lights, locks, windows, and horn—to ensure everything is working correctly.
Important Post-Installation Notes
While our service makes this a plug-and-play repair, some vehicle systems may require recalibration. If your airbag warning light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary to ensure proper brake light and traction control operation. Always refer to a factory service manual for vehicle-specific details.

Frequently Asked Questions
What is a BCM cloning service?
It’s a process where we transfer the essential programming and security data from your original, failing BCM to this replacement unit. This makes the new part plug-and-play, saving you from a costly trip to the dealership for programming.
Do I need to send my original BCM to you?
Yes. We need your original module to extract the vehicle-specific data. After you place your order, we will contact you with simple instructions on how to ship your part to us.
Will my keys and remote fobs still work?
Absolutely. Because we clone your original data, the replacement BCM will recognize your existing keys and remotes. No key relearn procedure is necessary.
Is this a difficult part to install myself?
For most people with basic hand tools, this is a very manageable DIY job. The 2011 Cruze BCM is typically located behind the driver’s side kick panel, making it relatively easy to access and swap out.
What if my airbag light comes on after installation?
This can sometimes happen. It simply means the new BCM needs to be synced with the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ can be performed with a professional-grade scan tool to resolve this.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module after sending it to us for the data transfer service.
