Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) acts as the central computer for your truck’s non-engine related electronic systems. It manages functions like your interior and exterior lights, power windows and locks, security system, wipers, and the HVAC climate control system.
Is this BCM difficult to install?
Installation is typically very simple. The BCM is usually located under the driver’s side dashboard near the steering column. Because this unit comes pre-programmed to your VIN, the process is plug-and-play and often takes less than 15 minutes with basic tools.
Why is VIN programming so important?
VIN programming loads your truck’s specific software and configurations onto the module. Without it, the BCM won’t communicate correctly with your vehicle’s other computers, leading to system malfunctions or the part not working at all. Our service saves you a mandatory and costly trip to the dealership.
Will this fix my airbag light with code B1001?
Yes, a faulty BCM is a common cause of the B1001 code. Replacing it often resolves the issue. However, in some cases, a post-installation procedure called “Setup SDM Primary Key in BCM” may be required using a professional scan tool to sync the new BCM with the airbag system and turn off the light.
Do I need to send my old part back?
No. We do not require a core return for this 2013 Silverado 3500 Body Control Module. You can keep your old part without any additional charges or hassle.
