Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer in your vehicle that manages and controls a wide variety of electronic accessories not related to the engine. This includes power windows, locks, interior and exterior lighting, the security system, wipers, and more. When it fails, these systems can become erratic or stop working altogether.
Is this BCM truly ‘plug and play’?
Yes. Because we program the module to your vehicle’s specific VIN before shipping, it eliminates the need for any additional programming or calibration by a dealer. In most cases, you simply install it, and it’s ready to go. However, some vehicles may require a simple relearn procedure as outlined in our post-install instructions.
How do I provide my VIN after purchase?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship your BCM until we receive this information, so please provide it promptly to avoid delays.
What if my airbag light is on after I install the new BCM?
In some cases, the new BCM may need to be synced with the airbag system’s computer (SDM). If the airbag light comes on, a ‘Setup SDM Primary Key in BCM’ procedure will need to be performed by a mechanic with a professional-grade scan tool. This is a standard procedure and is only required if the light appears.
Will this fix my specific electrical problem?
This Programmed 2003-2007 Sierra 1500 BCM is the correct solution for a vast majority of the electrical symptoms listed, such as non-working power accessories, lighting faults, and security issues. It is the most common point of failure for these problems. If your vehicle’s symptoms match those described, this module is the definitive fix.
Do I need to return my old BCM?
No. This product comes with no core charge. You are not required to send your original module back to us, which saves you the hassle and cost of return shipping.
