Is Your Chevrolet Impala Experiencing Strange Electrical Problems?
If your 2006-2013 Impala is acting possessed—with flickering lights, malfunctioning power windows, or a security system that has a mind of its own—a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central nervous system for your vehicle’s electronic accessories. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues. Ignoring these symptoms can lead to more significant problems, including a no-start condition that leaves you stranded. Don’t let a faulty module dictate your car’s reliability.
From the Diagnostic Bay
We had a 2011 Impala come into the shop with a classic case of BCM failure. The customer complained that the interior lights would stay on, the radio would shut off randomly, and the power door locks worked intermittently. They had already replaced the battery, thinking it was a simple power issue. After connecting our diagnostic scanner, we saw multiple communication error codes pointing directly to the BCM. Instead of sending them to a dealership for a costly replacement and programming session, we installed one of our pre-programmed modules. The entire process was done in under an hour, resolving all the electrical gremlins. The customer drove away with a perfectly functioning car, saving hundreds of dollars and a lot of time.
Symptoms of a Failing 2006-2013 Impala BCM
A faulty BCM can manifest in various ways. If you’re noticing any of the following issues, it’s a strong indicator that your Body Control Module needs replacement:
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors not working or operating on their own.
- ✔ The anti-theft or security system engaging randomly, preventing the car from starting.
- ✔ Inaccurate readings on the instrument cluster gauges.
- ✔ The radio or infotainment system turning on or off without command.
- ✔ Warning lights appearing on the dash, such as the airbag or brake light.
- ✔ Poor communication between the BCM and other vehicle modules, leading to diagnostic trouble codes.
The Simple, Reliable Solution: A VIN-Programmed BCM
This Body Control Module is the definitive solution for your vehicle’s electrical issues. We take the guesswork and hassle out of the repair process. Unlike a generic module from a parts store or salvage yard, this unit is meticulously programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This crucial step ensures that the BCM communicates flawlessly with your car’s existing systems, just like the original part from the factory.
Key Benefits:
- Plug & Play Installation: Because we program the module with the latest GM software updates using your VIN, you can avoid expensive dealership programming fees.
- Guaranteed Compatibility: This module is a direct replacement for a wide range of part numbers, including 15828601, 15921352, 20864767, 22860591, 25892622, and many more.
- No Core Charge: There is no need to send your old, faulty module back to us. You can keep it or dispose of it at your convenience.
Important Post-Installation Information
While this module is programmed for your vehicle, certain systems may require a relearn or synchronization procedure after installation. This is a standard part of the repair process for many modern vehicles. The most common procedures include:
- Airbag System Sync: If the airbag warning light is illuminated after you install the new BCM, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be needed to ensure correct operation of the brake lights and traction control system.
Please note: Specific procedures can vary. We always recommend consulting a factory service manual or a certified automotive technician for detailed instructions for your specific vehicle.
Frequently Asked Questions
Do I need to send you my VIN?
Yes, providing your vehicle’s 17-digit VIN is essential. We use it to program the module with the correct software and vehicle-specific options, ensuring it works correctly right out of the box.
Is this a difficult part to install?
For the 2006-2013 Impala, the BCM is typically located on the left-hand side of the dash. Installation is generally straightforward for someone with basic mechanical skills and tools. However, due to the potential need for post-install relearn procedures, professional installation may be preferred.
Will this BCM fix my car’s no-start problem?
If your no-start issue is caused by the anti-theft system being incorrectly triggered by a faulty BCM, then yes, this programmed module will resolve the problem. The VIN programming ensures the security handshake between the BCM and other modules is correct.
What happens if I don’t perform the post-installation procedures?
If required, failing to perform procedures like the Airbag System Sync will result in the airbag warning light remaining on. A brake pedal position relearn is crucial for safety systems like traction control and ABS. It’s best to check all systems after installation.
Is there a core charge for this part?
No, there is no core charge. You are not required to return your original BCM to us.
