Restore Your Impala’s Brain and End Electrical Chaos
If your 2006-2013 Chevy Impala is acting possessed—with flickering lights, a security system that won’t cooperate, power windows with a mind of their own, or intermittent no-start conditions—the culprit is very likely a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can turn your reliable sedan into a source of daily frustration. This isn’t just an inconvenience; it can be a critical safety issue if your exterior lights or security features fail at the wrong time.
Forget the expensive dealership visit and the hassle of coordinating programming. We offer a straightforward, reliable solution. This Body Control Module is meticulously tested and comes programmed with the latest GM software, specifically matched to your vehicle using your VIN. It’s a direct-fit replacement that restores the full functionality you depend on, getting you back on the road with confidence.
Case Study: A Tricky Diagnosis
I remember a 2011 Impala that came into my shop with a laundry list of bizarre electrical gremlins. The customer reported the radio would randomly shut off, the dome light would stay on, and occasionally, the car just wouldn’t start—no crank, nothing. The battery was new, and the alternator checked out. After connecting my scan tool, I found a flurry of U-codes, specifically a U0140 (Lost Communication With Body Control Module). This pointed directly to the BCM. After a quick inspection under the driver’s side dash, I found evidence of water intrusion from a leaky cowl seal, which had shorted the original module. Installing a pre-programmed 2006-2013 Impala BCM like this one solved every single issue instantly, saving the customer hundreds compared to the dealership’s quote.
Is Your Impala Showing These BCM Failure Signs?
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system light stays on, or the alarm goes off randomly.
- ✔ Key fob not working, even with a new battery.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Intermittent no-start or no-crank conditions.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication errors, such as U0140, U0155, or B1001.
A Straightforward Guide to BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: In the 2006-2013 Impala, the BCM is typically located behind the driver’s side of the dashboard, to the left of the steering column. You may need to remove the lower dash panel for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location. Reconnect all electrical connectors firmly, ensuring 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, radio, etc.—to confirm proper operation.
- ✔ Perform Relearns (If Needed): As noted below, you may need a professional scan tool to perform an Airbag System Sync or Brake Pedal Position Relearn if related warning lights are present after installation.
Important Post-Installation Steps
While this BCM is programmed for your VIN, some vehicle systems may require a final handshake to fully integrate. 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 compatible diagnostic tool. This ensures the safety system is properly synced.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician for your specific model.

Frequently Asked Questions
What does the Cloning Service involve?
Our Cloning Service means we program the replacement BCM with your vehicle’s specific VIN and the latest GM software before we ship it. This ensures it communicates correctly with your car’s other modules, making installation as simple as possible and saving you a trip to the dealer for programming.
Do I need to send my original BCM to you?
No, you do not need to send us your original part. We only require your vehicle’s 17-digit VIN to perform the programming. After you place your order, simply provide us with your VIN, and we’ll handle the rest.
Is this a difficult part for a DIYer to replace?
For someone with basic mechanical skills, replacing the BCM is very manageable. It typically involves removing a dash panel and a few bolts or clips. Since our module arrives pre-programmed, you eliminate the most complex part of the job. Just follow our installation guide and take your time.
What happens to my old BCM? Is there a core charge?
There is no core charge for this part. The service includes programming and returning your original module along with the new one. You can keep your old part or dispose of it as you see fit.
Will this fix my ‘Service Theft System’ message?
In many cases, yes. The BCM is integral to the Pass-Key/Pass-Lock anti-theft system. A failing BCM is a very common cause of security system faults and warning messages. Replacing it with our correctly programmed module often resolves these issues.
