Frequently Asked Questions
Is this BCM truly plug-and-play?
Yes! We program the module to your vehicle’s VIN before shipping. This ensures it works with your existing keys and options without needing a trip to the dealer for programming.
What if my airbag light is on after installation?
In some cases, an airbag light may appear. This requires a ‘Setup SDM Primary Key in BCM’ procedure using a professional scan tool. This syncs the new BCM with the airbag system and is a quick procedure for any qualified mechanic.
Where is the BCM located on my 2013 Silverado?
The Body Control Module is typically found under the driver’s side dashboard, often to the left of the steering column. It’s a black box with multiple large electrical connectors.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module without any additional fees or hassle.
Will this fix my specific electrical problem?
This module corrects issues directly controlled by the BCM, such as power accessories, lighting, and security functions. While it solves the most common electrical faults, always ensure your vehicle’s wiring and grounds are in good condition.
