Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s VIN before it ships. This allows for a simple plug-and-play installation without any need for expensive dealer tools or software.
Where is the BCM located on my vehicle?
On most compatible GM trucks and SUVs like the Silverado, Sierra, and Tahoe, the BCM is located under the driver’s side dashboard, near the steering column. On Express and Savana vans, it’s typically found in the center dash area.
Will this fix my airbag light?
While a faulty BCM can trigger an airbag light (often with code B1001), some vehicles may require an additional ‘Setup SDM Primary Key in BCM’ procedure after installation. This is a simple sync process that can be performed with a professional-grade scan tool to turn off the light.
Is this installation difficult for a DIYer?
Not at all. For most people, the installation is very straightforward and can be completed in under 5 minutes with basic hand tools. Simply disconnect the battery, locate and swap the old module with the new one, and reconnect the battery.
