Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer in your car that controls a wide range of electronic accessories not related to the engine. This includes power windows, locks, interior and exterior lighting, the security system, wipers, and more. When it fails, these systems can behave erratically.
Why do you need my vehicle’s VIN?
The Vehicle Identification Number (VIN) allows us to program the BCM with the specific software and settings for your car’s exact options and features. This makes the module a true plug-and-play component, ensuring all functions work correctly right after installation.
Is this part difficult to install?
The BCM is typically located under the driver’s side of the dashboard, near the steering column. For someone with basic mechanical skills and tools, it is a manageable job. However, if you are not comfortable working under the dash, we recommend having a qualified mechanic perform the installation. The key benefit is that the difficult programming step is already done for you.
What if my airbag light comes on after installation?
In some cases, the new BCM may need to be synced with the airbag system’s computer (SDM). If the airbag warning light is on after you install the module, a mechanic will need to perform a “Setup SDM Primary Key in BCM” procedure with a professional scan tool. This is a quick process that syncs the systems.
Do I need to perform any other procedures after installing the BCM?
Besides the potential airbag sync, a brake pedal position sensor relearn might be necessary on some models to ensure proper brake light and traction control operation. Always consult a service manual or a professional technician for guidance specific to your vehicle. This is a solid fix for your 2000-2004 Impala Monte Carlo BCM issues.
Is this a guaranteed fix for my car’s problem?
This BCM will fix problems directly caused by a faulty BCM. While the symptoms we’ve listed are extremely common for BCM failure in these vehicles, we always recommend proper diagnosis to confirm the BCM is the source of your issue before ordering.
