Frequently Asked Questions
What does a Body Control Module do?
The Body Control Module (BCM) acts as the central computer for your vehicle’s non-engine-related functions. It controls the power windows, door locks, interior and exterior lighting, security system, wipers, and climate control systems, ensuring they all work together correctly.
Is this module difficult to install?
Installation is typically very straightforward. The BCM is usually located under the driver’s side dashboard near the steering column. Because this module comes pre-programmed to your VIN, the physical installation is a simple plug-and-play process that often takes less than 15 minutes.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and configurations onto the module. Without it, the BCM won’t be able to communicate properly with other computers in your truck, leading to incorrect operation or complete failure of body systems. Our pre-programming service makes it ready to install right out of the box, saving you a mandatory and costly trip to the dealership.
What if my airbag light is on after installation?
In some cases, especially if you had an airbag 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 required if the airbag light appears after the new BCM is installed.
Does this part require a core charge?
No. We do not require you to return your old module, which simplifies the process and saves you the hassle and expense of a core return.
