Post-Installation Information
While this BCM is designed to be plug-and-play, some vehicles may require a simple relearn procedure after installation. If your airbag warning light illuminates, a professional scan tool will be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems. Additionally, a Brake Pedal Position sensor relearn may be necessary on some models to ensure proper brake light and traction control operation. Always consult a factory service manual or a qualified technician if you are unsure about these steps.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as the central hub for these functions.
Is this BCM truly plug-and-play?
Yes, for most vehicles. We program it with your VIN before shipping, so it should work upon installation without requiring a trip to the dealer. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your BCM without it.
What if my airbag light is on after I install the BCM?
If the airbag light comes on, it means the BCM needs to be electronically synced with the vehicle’s airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a repair shop with a professional-grade diagnostic tool.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Will this fit my 2007 Silverado ‘Classic’ model?
Yes, this BCM fits the 2007 ‘Classic’ style Silverado and Sierra pickups, which have the creased door skin characteristic of the 2003-2006 body style. Please check the detailed fitment list to confirm your specific options.
