Restore Full Functionality to Your 2006-2013 Chevrolet Impala
If you’re dealing with baffling electrical issues in your Chevy Impala—like flickering dash lights, power windows with a mind of their own, or a security light that prevents your car from starting—you’ve likely met the culprit: a failing Body Control Module (BCM). As an experienced technician, I’ve seen these symptoms countless times. The BCM is the central command for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and unpredictable problems. This isn’t just an inconvenience; it can affect your vehicle’s security and safety.
Solving Electrical Gremlins with a 2006-2013 Impala BCM
Don’t let a faulty module keep you off the road or force you into an expensive, time-consuming visit to the dealership. We offer a reliable, straightforward solution. This Body Control Module is not just a replacement part; it’s a complete service. We perform a cloning service, programming the module with the latest GM software updates specifically matched to your vehicle’s VIN. This means it arrives at your door ready for installation, saving you the hassle and cost of post-purchase programming.
Case Study: A Tricky Diagnosis
A few months back, a 2011 Impala was brought to my shop with a classic ‘haunted car’ complaint. The interior lights would pulse, the radio would cut out, and the door locks would cycle randomly while driving. The owner had already replaced the battery and alternator with no success. After hooking up my scan tool, I saw several communication error codes (U-codes) pointing to the BCM. Instead of a complex rewiring job, the fix was a properly programmed BCM. Once installed, all the phantom electrical issues vanished. This is a common story, and a new BCM is often the simple, effective answer.
Common Signs of a Failing BCM
If your vehicle is exhibiting any of these behaviors, a failing BCM is the most likely cause. A proper diagnosis is always recommended, but these are the tell-tale signs I look for first:
- ✔ Erratic power window or power lock operation.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Interior or exterior lights flicker, stay on, or don’t work at all.
- ✔ The horn honks unexpectedly or doesn’t work when pressed.
- ✔ Wipers operate intermittently or won’t turn off.
- ✔ False warnings on the instrument cluster (e.g., ‘Door Ajar’).
- ✔ Diagnostic Trouble Codes (DTCs) like U0140, B1001, or other B-series and U-series codes related to body systems.
A Straightforward Guide to Installation
For the confident DIYer or professional mechanic, swapping the BCM is a manageable job. Our VIN programming makes the process much simpler.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On the 2006-2013 Impala, the BCM is typically found on the left (driver’s) side of the dash, often near the steering column or behind the lower dash panel.
- Remove the Old Module: Carefully disconnect the electrical connectors. They have locking tabs that need to be released. Once unplugged, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Seat your new, pre-programmed BCM into the mounting bracket and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, locks, windows, wipers, etc.
- Perform Relearns (If Needed): As noted in our post-installation procedures, you may need a professional scan tool to perform an ‘Airbag System Sync’ or ‘Brake Pedal Position Relearn’ if related warning lights appear.
Important Post-Installation Steps
While our cloning service handles the main programming, some vehicle systems may require a handshake with the new BCM. Be aware of these potential procedures:
- Airbag System Sync: If your airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems. This requires a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: On some models, this recalibration might be necessary to ensure brake lights and stability control work correctly.

Frequently Asked Questions
How does the programming service work?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. We use this to access the latest GM software and program the module specifically for your car’s configuration. This ensures it works correctly right out of the box.
Do I need to send my old BCM to you?
No, this is not a repair service for your original part. We provide a replacement module that is programmed using your VIN. Per our policy, your original module is always returned to you along with the programmed replacement unit we send. We do not keep the core.
Is this a plug-and-play part?
For the most part, yes. Our VIN programming handles the critical setup. However, as with any complex electronic component, some vehicles may require minor post-installation relearn procedures for systems like the airbags or brake sensor, which may require a professional scan tool.
Will this fix my car’s ‘Service Theft System’ message?
A failing BCM is a very common cause of this issue. By restoring proper communication between your ignition key, the security system, and the rest of the vehicle, this programmed BCM can resolve that problem in many cases.
What if I have an airbag light after installation?
This is an indication that the BCM and the airbag’s Sensing and Diagnostic Module (SDM) need to be synced. A mechanic with a capable bi-directional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
