Restore Full Functionality to Your GM Vehicle
Is your 2006–2013 Chevrolet Impala suffering from strange and unpredictable electrical problems? As the central command center for your vehicle’s body electronics, a failing Body Control Module (BCM) can cause a cascade of frustrating issues that can be difficult to diagnose. From power windows that won’t budge to a security system that acts up, these aren’t just annoyances—they can compromise your vehicle’s safety and reliability. This isn’t a part you can afford to ignore.

A Technician’s Notebook
“A customer’s 2011 Impala came into the shop last month with a truly baffling set of symptoms. The radio would turn on and off by itself, the driver’s side power window worked intermittently, and the anti-theft light would stay illuminated, sometimes preventing the car from starting. The owner had already replaced the battery and checked the alternator. After hooking up the scan tool, I saw a slew of communication error codes (U-codes) pointing to a network issue. Instead of chasing ghosts, I went straight for the BCM. Water intrusion from a leaky windshield cowl had caused corrosion on one of the main connectors. Swapping in a pre-programmed BCM like this one solved every single issue instantly. It’s a classic failure pattern on these platforms.”
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system light is on, or the alarm triggers randomly.
- ✔ Key fob fails to lock or unlock the doors.
- ✔ Wipers behaving unpredictably or not parking in the correct position.
- ✔ Communication errors with other modules, leading to various warning lights on the dash.
- ✔ In some cases, a no-start condition due to security system lock-out.
A Straightforward Guide to Installation
Installing your new 2006–2013 Impala BCM is a manageable job for a confident DIYer. On most Impalas, the BCM is located on the driver’s side, up under the dashboard near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to fully discharge.
- Access the Module: You may need to remove the lower dash panel or knee bolster trim to gain clear access to the BCM. These are typically held in by a few screws or clips.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be pressed to release. Once disconnected, unbolt or unclip the old module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical connectors. You should hear a click as they lock into place.
- Reassemble and Reconnect: Reinstall any trim panels you removed and then reconnect the negative battery terminal.
- Final Procedures: Proceed with the necessary post-installation steps outlined below to ensure all systems, including safety features, are correctly initialized.
Important Post-Installation Requirements
After installing your new BCM, a few final steps are essential for restoring full, safe operation. Failure to perform these initializations can result in warning lights and improperly functioning systems.
- Airbag System Reset: To clear the airbag warning light, the ‘Setup SDM Primary Key in BCM’ procedure must be performed. This requires a professional-grade diagnostic scan tool and ensures the new BCM can communicate correctly with the Supplemental Restraint System.
- Brake Pedal Position Sensor (BPPS) Learn: Some vehicles require a recalibration of the brake pedal sensor after BCM replacement. This procedure ensures the brake lights and stability control systems function as intended.
Note: While these are common procedures for GM vehicles of this era, the exact steps can vary. We strongly recommend consulting your vehicle’s service manual or seeking help from a qualified technician if you are unfamiliar with these processes.

Frequently Asked Questions about the 2006–2013 Impala BCM
Do I need to get this BCM programmed by a dealer?
No. We handle the programming for you before shipment. Just provide your vehicle’s VIN at checkout, and the module will arrive with the latest GM software, ready for installation and final relearn procedures.
Where is the BCM located on my 2009 Impala?
On the 2006-2013 Impala, the Body Control Module is typically found under the driver’s side of the dashboard, often attached to a bracket near the steering column or the fuse panel area.
Will this fix the ‘Service Theft System’ message on my dash?
A faulty BCM is a very common cause of security system issues, including the ‘Service Theft System’ message and no-start problems. Replacing it with this programmed unit is a very likely fix for that issue.
What tools are needed for the post-installation procedures?
The ‘Setup SDM Primary Key’ and ‘Brake Pedal Position Sensor Learn’ procedures require a bi-directional scan tool, such as a GM Tech 2 or a comparable professional-grade diagnostic tool. Most basic code readers cannot perform these functions.
Is this a new or used part?
This is a quality, tested, and guaranteed functional component that has been fully inspected and prepared for service. It is programmed with fresh, vehicle-specific software to ensure reliable performance.
