Are you chasing down frustrating electrical gremlins in your 2011 Chevy Cruze or another compatible GM vehicle? When your lights flicker, windows refuse to work, or the car won’t start, the Body Control Module (BCM) is often the culprit. Instead of facing a costly trip to the dealership for diagnostics and programming, we offer a straightforward, reliable solution. This listing is for a replacement BCM that comes professionally programmed with your vehicle’s exact data, making the repair process as simple as plug-and-play.
Our unique cloning service is the key. You simply ship your original BCM to us. Once it arrives, my team of technicians will transfer all the critical information—including VIN, key data, and specific options—to this replacement module. We then ship the fully programmed BCM back to you, ready for immediate installation. This process eliminates the need for expensive factory scan tools and ensures all your vehicle’s features work correctly right out of the box.
Signs Your Body Control Module is Failing
A BCM is the central hub for your vehicle’s body electronics. When it starts to fail, the symptoms can be confusing and widespread. I’ve seen these issues hundreds of times in the shop. Look out for these common indicators:
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or security system acting up intermittently.
- ✔ The horn sounding randomly or not at all.
- ✔ Wipers turning on by themselves or not responding.
- ✔ A no-start condition where the engine cranks but won’t fire, often accompanied by a security light.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or other U-series codes, stored in the system.
From the Diagnostic Bay: A Cruze Conundrum
A customer brought in their 2011 Cruze last month with a truly baffling set of symptoms. The dash lights would flicker, the radio would cut out, and sometimes the car just wouldn’t start. They had already replaced the battery and checked the alternator, with no luck. After connecting my scan tool, I saw a dozen communication codes pointing to a network failure. Instead of a complex wiring issue, my experience pointed straight to the 2011 Cruze BCM. The internal logic was failing, causing chaos on the vehicle’s data bus. We performed this exact cloning service, and the customer had their car back the next day, running perfectly, for a fraction of the dealer’s quote.
A Straightforward Guide to Your BCM Installation
Installing your pre-programmed BCM is a manageable job for a DIY enthusiast. Here’s a general guide to get you through it:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On a Chevy Cruze, the BCM is typically found in the driver’s side footwell, behind the kick panel to the left of the pedals. For other models, its location may be under the dash.
- Remove Connectors: Carefully unplug all the wiring harness connectors from the old BCM. They have locking tabs that need to be depressed. Do not force them.
- Swap the Module: Unbolt or unclip the original BCM from its mounting bracket and remove it. Place your new, pre-programmed module in the same position and secure it.
- Reconnect Everything: Plug all wiring harnesses back into the correct ports on your new BCM. They are often color-coded or shaped to only fit in the correct spot.
- Power Up: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions—lights, locks, windows, etc.—before starting the engine.
Important Post-Installation Information
While our cloning service handles the vast majority of programming needs, some vehicle systems may require a quick sync after installation. Please be aware of the following possibilities:
- Airbag System Sync: If you see an airbag warning light after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the BCM with the airbag module and can be done with a professional-grade scan tool.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn might be necessary to ensure your brake lights and traction control system function as intended.
- No Core Required: You do not need to send your old part back to us after the repair. There is no core charge.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is a process where we transfer the complete software and vehicle-specific data (like VIN and security information) from your original BCM to the replacement unit. This makes the new module a perfect digital copy, allowing it to work in your car without any additional programming.
Why do I have to ship my original BCM to you?
Your original BCM holds the unique data that makes your car run correctly. We need it to perform the cloning service. This is the most reliable way to ensure a true plug-and-play solution and avoid security system lockouts or feature incompatibility.
Will this fix my car’s electrical problems for good?
If your vehicle’s issues are caused by a faulty BCM, this programmed replacement module is the definitive fix. It restores the central command center for your car’s body electronics to full working order.
Do I need a mechanic to install this?
While the physical installation is straightforward for many DIYers, some post-installation procedures like an airbag sync may require a professional scan tool. If you are not comfortable working on your car’s electrical systems, we recommend seeking help from a qualified technician.
What happens if the airbag light comes on after I install it?
This is a known possibility. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag control module (SDM). A mechanic with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Is there a core charge for this part?
No, there is no core charge. Once we have cloned the data from your original module, you can keep it or dispose of it.
