Installation and Post-Install Notes
Installation is straightforward for those with mechanical experience. The BCM is typically located under the driver’s side dash, near the steering column, or in the center dash area for van models. Once installed, while our programming handles the majority of the setup, some vehicles may require additional sync procedures. If your airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a Brake Pedal Position Relearn might be necessary. Best of all, there is no core charge, so you can keep your original module.
Frequently Asked Questions
What does the BCM actually do?
The Body Control Module (BCM) acts as the brain for your vehicle’s electronic accessories. It controls functions like power windows, power locks, interior and exterior lighting, the security system, wipers, and more.
Do I need to have this BCM programmed by a dealer?
No. We program the module to your vehicle’s VIN before we ship it to you. It arrives ready for installation, saving you time and the expense of dealer programming.
Where is the BCM located on my 2002 GM truck?
On most trucks like the Silverado, Sierra, and Tahoe, the BCM is located under the driver’s side of the dashboard, near the steering column. On vans like the Astro and Safari, it’s typically found behind the center dash panel.
What if my airbag light is on after I install the new BCM?
This can happen. It means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A technician with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
Is there a core charge for this part?
