Tired of Unpredictable Electrical Problems in Your Impala?
Is your 2006-2013 Chevrolet Impala acting possessed? Flickering dashboard lights, power windows with a mind of their own, or a security system that randomly prevents your car from starting are all classic signs of a failing Body Control Module (BCM).

This is the direct, reliable solution you’ve been looking for.
We offer a genuine GM Body Control Module, part number 15921353, that arrives at your door fully programmed to your vehicle’s specific VIN. We load the latest GM software updates, ensuring optimal performance and compatibility. This isn’t a generic, one-size-fits-all part; it’s a component configured specifically for your car, eliminating the need for an expensive trip to the dealership for programming.
A Technician’s Notebook: The Impala Ghost
I once had a 2011 Impala in my bay that was driving its owner crazy. The radio would shut off, the interior lights would pulse, and occasionally the car just wouldn’t start—but there were no engine codes. After checking the battery and alternator, my diagnostics pointed to the network. The BCM wasn’t communicating consistently. These modules are notorious for internal solder joint failures that cause intermittent connections. After installing a VIN-programmed BCM like this one, every single ghost-like issue vanished. It’s a common failure, and a pre-programmed module is the fastest, most reliable fix.
Common Signs of a Failing BCM
If you’re experiencing any of these issues, a faulty BCM is the likely culprit. A failing module can often trigger communication error codes like U0140, U0155, or other U-series codes.
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security or anti-theft system engaging randomly, causing a no-start condition.
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ Inaccurate gauge readings on the instrument cluster.
- ✔ “Service Stabilitrak” or “Service Traction Control” messages appearing without a clear cause.
A Straightforward Guide to Installation
For the handy DIYer, replacing the BCM on an Impala is a manageable job. This pre-programmed module makes the process much simpler.
- Safety First: Always disconnect the negative terminal from your car’s battery and wait a few minutes before starting work.
- 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 depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, VIN-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—lights, locks, windows, radio, etc.—to confirm the repair.

Important Post-Installation Information
While this module is plug-and-play for most functions, some vehicle systems may require a ‘relearn’ or synchronization procedure after installation. This is normal. The most common are:
- Airbag System Sync: If your 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 BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary for proper brake light and traction control operation.
Disclaimer: Always consult a factory service manual or a certified technician if you are unsure about any step of the installation or post-install procedures.
Frequently Asked Questions
Will I need to program this BCM?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN at checkout, and the module will arrive with the latest GM software, ready for installation.
What does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, interior/exterior lighting, the security system, and the climate controls.
Where is the BCM on a 2008 Impala?
On most 2006-2013 Impalas, the BCM is located behind the driver’s side lower dashboard, to the left of the steering column. You will likely need to remove a plastic trim panel to access it.
Is there a core charge for my old part?
Absolutely not. There is no core charge on this BCM. You can keep your old module, so there’s no need to worry about return shipping.
What if my airbag light turns on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to your car’s airbag module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
