Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that manages and controls a wide range of electronic accessories not related to the engine. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC climate control system.
Is this part difficult to install?
Installation is typically very straightforward. The BCM is usually located under the driver’s side dashboard, near the steering column. For most models, it’s a simple plug-and-play process that can be completed in under 10 minutes with basic tools. No complex wiring is required.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module without any extra fees or hassle, simplifying the repair process for you.
What if the airbag light stays on after installation?
In some cases, particularly if you had an airbag-related code like B1001, the new BCM may need to be synced with the airbag system’s computer (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed with a professional-grade scan tool. It is only necessary if the airbag light appears after the new part is installed.
How do I know this is the exact part I need?
This VIN Programmed 25844480 Body Control Module is a direct replacement for many part numbers. The best way to confirm is to check the part number on your original module.
