Restore Your Vehicle’s Electrical Functions
Are you experiencing baffling electrical problems in your Chevrolet Impala or other GM vehicle? Issues like flickering interior or exterior lights, malfunctioning power windows and locks, a security system that acts up, or a battery that drains overnight are classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of frustrating and unpredictable problems. Don’t let these electrical gremlins keep you off the road. This replacement Body Control Module is the reliable, straightforward solution to restore your vehicle’s functionality and your peace of mind.
From the Diagnostic Bay
We had a 2011 Impala come in with a classic parasitic draw issue. The owner had replaced the battery twice, but it would still be dead every few mornings. After hooking up a multimeter, we saw a significant current draw even after the car was shut down. By pulling fuses one by one, we isolated the circuit to the BCM. The module wasn’t properly entering its ‘sleep’ mode, keeping other systems awake and slowly draining the battery. We installed a VIN-programmed BCM, and the draw disappeared immediately. It’s a common failure mode that can be incredibly frustrating for owners until the root cause is found.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Flickering or inoperative dashboard lights and gauges.
- ✔ Headlights, taillights, or interior lights staying on or not turning on at all.
- ✔ Unexplained battery drain leading to a no-start condition.
- ✔ Security system or keyless entry malfunctions.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ False warnings on the driver information center.
Your Direct-Fit Impala Body Control Module Solution
This isn’t just a generic part off the shelf. We provide a complete, plug-and-play solution tailored to your specific vehicle. When you place your order, you provide us with your Vehicle Identification Number (VIN). Our technicians then program this module with the latest, most stable software updates directly from GM. This critical step ensures that the BCM communicates perfectly with your vehicle’s other computers, like the Engine Control Module (ECM) and Transmission Control Module (TCM). This eliminates the need for an expensive trip to the dealership for programming, saving you time and money.
Installation and Post-Install Procedures
Installation is typically straightforward, as the module is designed to be a direct replacement for the original unit. However, with modern complex vehicle systems, a few additional steps may be required after the physical installation is complete.
- Airbag System Sync: In some cases, the new BCM may need to be synchronized with the vehicle’s airbag system (SDM). If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible professional scan tool.
- Brake Pedal Position Relearn: To ensure proper operation of the brake lights and stability control systems, a brake pedal position sensor relearn might be necessary. This also requires a high-level diagnostic tool.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
No Core Charge Required
We make the process simple. There is no core charge associated with this part. You are not required to return your old, malfunctioning module, saving you the hassle and cost of return shipping.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential for programming the Body Control Module correctly. It allows us to load the exact software and vehicle-specific options (like keyless entry, power seats, etc.) that your car was built with. This ensures seamless integration and functionality right out of the box.
Is this part difficult to install?
For someone with moderate mechanical experience, the physical replacement is generally not difficult. The BCM is typically located under the dashboard on the driver’s side. However, post-installation procedures like the airbag system sync or brake pedal relearn may require professional-grade scan tools that most DIY mechanics do not own.
Do I need to return my old BCM?
No. This product comes with no core charge. You can keep your original module, which saves you the time, cost, and complexity of packaging and shipping the old part back to us.
What happens if my airbag light is on after installation?
An illuminated airbag light after installation indicates that the new BCM needs to be electronically synchronized with the airbag’s Sensing and Diagnostic Module (SDM). This requires a specific procedure called ‘Setup SDM Primary Key in BCM,’ which must be performed by a repair shop with an advanced diagnostic tool.
Will this fix my specific electrical problem?
The BCM controls a wide array of body functions, and this part is the definitive solution for a faulty module. If your vehicle exhibits multiple symptoms from the list above, a failing BCM is the most likely cause. However, proper vehicle diagnosis is always recommended to rule out other issues like bad wiring or faulty switches.
