This module is engineered to meet or exceed original equipment standards, ensuring long-lasting durability and performance. Installation is straightforward for those with basic mechanical skills, typically located under the driver’s side dashboard. While the process is plug-and-play, some vehicles may require a post-installation procedure. If the airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. In some cases, a ‘Brake Pedal Position Relearn’ may also be necessary. Best of all, there is no core charge—you can keep your old part without any extra fees.
Frequently Asked Questions
Frequently Asked Questions
What does a BCM do on a Chevy Silverado?
The Body Control Module (BCM) acts as the central computer for your truck’s body electronics. It manages non-engine related functions like power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system.
Will this BCM need to be programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. This ensures it is ready for installation right out of the box, saving you time and the expense of dealership programming.
Where is the BCM located on a 2009 Silverado 3500?
The BCM is typically located inside the cabin, under the driver’s side of the dashboard, often near the steering column. Installation usually takes less than 15 minutes.
My airbag light is on after installing the new BCM. What do I do?
This is a common security feature. You will need a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with your vehicle’s airbag system (SDM) and will turn off the light.
Does this part come with a warranty?
