Restore Full Functionality to Your Vehicle’s Electronics
Is your GM vehicle plagued by strange and frustrating electrical problems? Flickering lights, malfunctioning power windows or locks, a security system that acts up, or warning lights that won’t go away are all classic signs of a failing Body Control Module (BCM). The BCM acts as the central computer for your car’s body and accessory functions. When it fails, it can cause a cascade of seemingly unrelated issues that can be difficult to diagnose. This replacement GM Body Control Module is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
From the Diagnostic Bay
We recently had a 2011 Chevy Impala in the shop with a list of bizarre symptoms. The customer reported that the radio would sometimes not turn on, the driver’s side window worked intermittently, and the key fob would randomly stop working. A scan tool showed multiple communication errors with various modules. Instead of chasing individual components, we went straight to the BCM. A faulty Body Control Module was disrupting the entire communication network. Installing a VIN-programmed unit like this one resolved all issues in a single repair, saving the customer time and money.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Vehicle security system or keyless entry malfunctions.
- ✔ Horn sounding unexpectedly or not working at all.
- ✔ Wipers behaving erratically or not parking in the correct position.
- ✔ Multiple warning lights on the dashboard with no other apparent cause.
- ✔ Communication errors with other vehicle modules when using a diagnostic scan tool.
Why Choose Our Programmed GM Body Control Module?
Getting your vehicle back on the road shouldn’t be complicated. That’s why we offer a simple, effective solution. Unlike a standard replacement part that requires a trip to the dealership for expensive programming, this BCM arrives at your door ready for installation. We use your vehicle’s VIN to flash the module with the latest GM software updates, ensuring perfect compatibility and function right out of the box. This plug-and-play approach saves you hundreds of dollars in dealer fees and eliminates the hassle of coordinating a tow or a special appointment.
Installation and Post-Install Notes
While the physical installation is often a direct swap, some vehicles may require simple relearn procedures after the new BCM is connected. This is a normal part of the process as other modules in the vehicle sync with the new BCM.
- Airbag System Sync: If your airbag warning light illuminates after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control operation.
- No Core Charge: You are not required to send your old, faulty module back to us.
Please verify your part number against the extensive list provided and consult your vehicle’s service manual for the specific location of the BCM. By providing your VIN, you ensure a seamless repair process.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. This saves you the time, cost, and hassle of a dealership visit.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your VIN. You can also add your VIN to the notes section during checkout for the fastest service.
What if my airbag light comes on after I install the new module?
This is not uncommon. It simply means the new BCM needs to be electronically introduced to the airbag system. A qualified technician with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
Is this a difficult part to install myself?
The physical replacement is typically straightforward for someone with basic mechanical skills, involving disconnecting the battery and swapping the module. However, be aware that post-installation electronic relearn procedures, as mentioned, may be required.
How can I be sure this part fits my vehicle?
This module replaces a wide range of GM part numbers. Please check the fitment list on this page and match one of the part numbers to your original module. Providing your VIN is the best way to guarantee perfect compatibility.
