Your Plug-and-Play 2007-2011 Silverado Body Control Module Solution
Don’t let a faulty module keep your truck sidelined. Our key advantage is providing a BCM that is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical step ensures complete compatibility with your truck’s existing systems and options. You can avoid the time, expense, and hassle of a dealership visit for programming. Simply install the module, and you’re ready to go. Built to stringent OEM standards, this module ensures reliable, long-term performance and is backed by a one-year warranty. With no core charge, you can keep your old part without any extra fees.
Installation is typically straightforward, with the BCM located under the driver’s side dash near the steering column. While the physical swap is simple, be aware of potential post-installation procedures. If an airbag light is present after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ function. Similarly, a Brake Pedal Position Relearn may be needed on some models to ensure proper brake light and stability control operation. Always consult a service manual for your specific vehicle if you are unsure.
Frequently Asked Questions
What does a Body Control Module do on a Silverado?
The BCM is a computer that manages and controls most of your truck’s non-engine related electronic systems. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC climate control system.
Why is VIN programming so important for this part?
VIN programming loads your truck’s specific software and configuration into the BCM. This ensures it communicates correctly with other modules and that all features your vehicle was built with (like power seats, specific lighting, etc.) function as intended. Without it, the part will not work correctly.
Will this BCM fix my airbag light with code B1001?
A faulty BCM is a common cause of the B1001 code. Replacing it will likely solve the root problem, but the airbag system will need to be re-synced. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
Is this part difficult to install myself?
The physical installation is relatively easy for someone with basic mechanical skills, as the BCM is usually accessible under the steering column. However, be prepared for potential electronic relearn procedures that may require a specialized scan tool.
Do I need to return my old BCM?
No. We do not require you to send back your original part. There is no core charge associated with this purchase, saving you time and return shipping costs.
