Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the central computer for your van’s non-engine related electronic systems. It manages functions like the power windows, door locks, security system, interior and exterior lighting, wipers, and the HVAC climate control system.
Why is VIN programming so important?
VIN programming loads your van’s specific software and options into the BCM. Without it, the module won’t recognize your vehicle’s features, leading to system malfunctions or a complete failure to operate. Our pre-programming service makes the part ready to install right out of the box.
How difficult is the installation?
For the Express and Savana vans, the BCM is typically located in the center dash. Installation is straightforward and usually takes less than 15 minutes. You simply disconnect the battery, remove the trim panels to access the old module, unplug its electrical connectors, and swap in the new one.
My airbag light is on. Will this fix it?
A faulty BCM can cause the airbag light to illuminate. After installing the new module, if the light remains on, a simple ‘Setup SDM Primary Key in BCM’ procedure may be needed using a professional scan tool to sync the systems. This is a common final step for this repair.
Do I have to send my old BCM back?
No. There is no core charge for this part. You can keep or dispose of your old module, making the process simpler and more convenient for you.
Will this BCM fit other GM trucks or SUVs?
Yes, this part number (15116066) is compatible with a wide range of 2002-2007 GM vehicles, including the Silverado, Sierra, Tahoe, Yukon, Suburban, and Escalade. Always verify the part number and your vehicle’s options to ensure proper fitment.
