Frequently Asked Questions
What does a Body Control Module do on a Silverado?
The BCM acts as the central hub for your truck’s body electronics. It controls non-engine related functions like power windows, door locks, interior/exterior lights, the security system, wipers, and the HVAC system. When it fails, these systems can become erratic or stop working altogether.
Is this BCM difficult to install?
No, installation is straightforward for most DIYers. The BCM is typically located under the steering column. The process involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors to the new module. Since it’s pre-programmed, no special tools are required for setup.
Will this fix my airbag light?
In many cases, a faulty BCM can trigger an airbag light with codes like B1001. Replacing the BCM often resolves this. However, if the light remains on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure may need to be performed with a professional scan tool to sync the systems.
Do I need to send my old part back?
No. We do not require a core return for this Body Control Module. You can keep your old part, which simplifies the process and saves you the hassle and expense of return shipping.
How do I provide my vehicle’s VIN?
After you place your order, we will contact you to request your vehicle’s 17-digit VIN. This is a critical step that allows us to program the module specifically for your truck, ensuring a perfect plug-and-play installation.
