Restore Control Over Your Impala’s Electronics
Are you dealing with baffling electrical problems in your 2006-2013 Chevrolet Impala? One moment the power locks work, the next they don’t. Maybe the security light is on, preventing your car from starting, or the interior lights have a mind of their own. These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM), the central command center for your vehicle’s body electronics. Instead of facing a costly trip to the dealership for diagnostics and programming, take control with this direct-fit, VIN-programmed BCM.
We make the process simple. After your purchase, provide us with your vehicle’s VIN. Our technicians will then program this module with the very latest GM-certified software specific to your Impala. This ensures seamless integration and functionality right out of the box, restoring your car’s features to factory-perfect operation. This is the definitive solution for a properly diagnosed 2006-2013 Impala BCM failure.
A Technician’s Notebook: The Ghost in the Machine
I once had a 2008 Impala in the bay that was driving its owner crazy. The complaint was ‘it does weird stuff.’ The radio would shut off, the dome light would flicker while driving, and occasionally the security system would disable the starter. The owner had already replaced the battery and checked fuses. After hooking up the scan tool, I saw a slew of U-codes (communication errors) pointing to a network problem. In my 20+ years of experience, when you see that many unrelated systems acting up, the BCM is the prime suspect. It’s the traffic cop for all those electronic modules, and when it fails, chaos ensues. We installed a VIN-programmed BCM, and every single issue vanished instantly. It wasn’t a ghost; it was just a faulty BCM.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The security or anti-theft light is illuminated, causing a no-start condition.
- ✔ Instrument cluster gauges behaving erratically or not working.
- ✔ False warnings on the driver information center (e.g., ‘Service Tire Monitor System’).
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), often in the U-code family (e.g., U0140, U0155).
- ✔ A/C and climate control blower motor inoperative.
Your Straightforward Installation Guide
- ✔ Safety First: Disconnect the negative terminal from your car’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On the 2006-2013 Impala, the BCM is typically located on the left-hand (driver’s) side of the dashboard, often behind the lower dash panel near the steering column.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be pressed. Once disconnected, unbolt or unclip the old BCM and remove it from the vehicle.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely plug in all the electrical connectors, ensuring they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position (without starting) for 10-15 seconds, then start the vehicle. Test all functions like lights, locks, and windows.
- ✔ Perform Relearns (If Needed): As noted below, some vehicles may require a Brake Pedal Position Relearn or an Airbag System Sync if a warning light appears. This is not always necessary but is a possibility.
Important Post-Installation Information
While we program the module to your VIN for a streamlined installation, some GM security and safety systems may require a final handshake with the new module. Please be aware of the following potential procedures:
- 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 new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light and traction control operation.
- No Core Charge: You are not required to return your old module. There is no core charge or fee associated with this purchase.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician for your specific model’s procedures.

Frequently Asked Questions
Do I have to return my old BCM?
No. This product comes with no core charge, so you can keep your original module without any extra fees.
How do I give you my VIN for programming?
After you complete your purchase, you can send us a message with your 17-digit VIN. We will program the module before shipping it to you.
Is this BCM difficult to install?
For most DIYers, the physical installation is straightforward. Because it comes pre-programmed, you avoid the most difficult step. However, be aware that some vehicles may require a simple relearn procedure as mentioned in our description.
What if the airbag light turns on after I install it?
This is a known possibility. It means the new BCM needs to be electronically synced with the airbag module using a ‘Setup SDM Primary Key’ procedure, which requires a professional-grade diagnostic tool.
Will this fix my car’s specific electrical problem?
This module will correct any issues directly caused by a faulty BCM. We strongly recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the source of your problems before ordering.
My car isn’t an Impala. Will this still fit?
Yes, absolutely. This BCM fits a very wide range of GM cars, trucks, and SUVs. Please check the detailed ‘Verified Vehicle Compatibility’ list above to confirm it fits your specific model.
