Is Your Chevrolet Impala Experiencing Strange Electrical Problems?
The Body Control Module (BCM) is the central nervous system for your vehicle’s electronic accessories. It manages everything from your power windows and door locks to the interior lights, security system, and dashboard warnings. When the BCM starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues that can be difficult to diagnose. Instead of spending a fortune at the dealership, get a reliable, plug-and-play solution that restores your car’s functionality.
From the Diagnostic Bay
We once had a 2011 Impala in the shop where the owner had already replaced the driver’s side window motor twice and the master switch once. The window would still work intermittently. After checking the wiring and finding no faults, we traced the problem back to a failing BCM. The internal relays were worn, sending erratic signals. A new, programmed BCM fixed the issue instantly, saving the customer from replacing more unnecessary parts. Don’t chase ghosts in the machine—address the source of the problem.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The vehicle’s security system engaging randomly or preventing the car from starting.
- ✔ Horn honking unexpectedly.
- ✔ Inaccurate readings on the instrument cluster or warning lights that won’t turn off.
- ✔ Communication errors when using a diagnostic scan tool.

Post-Installation Procedures
After installation, some vehicles may require additional steps to ensure all systems are synchronized. These are standard procedures that can often be performed with a capable bidirectional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, the ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the systems. This is only required if the light is on.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be needed on certain models to ensure correct brake light and traction control operation.
Please consult a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that controls and monitors most of your vehicle’s non-engine related electronic functions, such as power locks, windows, lights, wipers, security system, and instrument cluster.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your car’s specific options and features. This makes the installation process plug-and-play and avoids a costly trip to the dealer for programming.
Is this BCM difficult to install?
For a 2006-2013 Impala, the BCM is typically located on the left-hand side of the dash. The physical replacement is straightforward for someone with basic mechanical skills. The most critical part is ensuring any post-install relearn procedures are performed if required.
What happens if I don’t do the post-installation procedures?
If your vehicle requires a procedure like the Airbag System Sync and it is not performed, the airbag warning light may remain on. Similarly, not performing a brake pedal relearn could affect brake light or traction control functionality.
Is there a core charge?
No, there is no core charge for this module. You can keep your original part without needing to send it back.
