Frequently Asked Questions
Do I need to take my truck to the dealer after installation?
No. This BCM is pre-programmed to your vehicle’s VIN, so it is ready to install and function without any additional dealership programming. This saves you time and money.
What tools are required for installation?
Installation is typically simple, requiring basic hand tools like a socket set or screwdriver to remove the lower dash panel. The BCM is usually held in by a few small bolts or clips and is located under the steering column.
My airbag light is on. Will this fix it?
This BCM can resolve airbag light issues caused by internal module failure (like DTC B1001). However, if the light remains on after installation, a special ‘Setup SDM Primary Key’ procedure may need to be performed with a professional scan tool to sync the BCM with the airbag system.
Is this compatible with my 2012 Silverado 2500?
This module fits a wide range of 2007-2013 GM trucks and SUVs. It is interchangeable with many part numbers, including those found in the 2012 Silverado. Please verify the part number from your original module or contact us with your VIN to ensure perfect compatibility.
What does ‘No Core Charge’ mean?
It means you do not have to send your old, faulty BCM back to us. You can keep it or dispose of it yourself, simplifying the process and saving you the hassle and expense of return shipping.
