Frequently Asked Questions
What does a Body Control Module do on my Sierra Denali?
The BCM is a computer that controls and monitors most of your truck’s non-engine related electronic functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system. When it fails, these systems can become erratic or stop working altogether.
Is this BCM difficult to install?
Installation is typically straightforward for those with basic mechanical skills. The BCM is usually located under the driver’s side dashboard near the steering column. The physical replacement often takes less than 15 minutes. Since it comes pre-programmed, no complex computer work is needed for most vehicles.
Will this module require a trip to the dealer?
No. Our main service is programming this module to your vehicle’s VIN before it ships. This allows you to install it and have it work immediately, bypassing the need for expensive programming services at a dealership.
What happens if my airbag light is on after installation?
In some cases, particularly if you have an airbag-related code like B1001, an additional procedure called ‘Setup SDM Primary Key in BCM’ may be required. This is a simple sync procedure that can be performed with an advanced, bi-directional scan tool and ensures the new BCM communicates correctly with the airbag system.
How do I know this is the correct part for my truck?
This module is compatible with a wide range of 2007-2013 GM trucks and SUVs. The best way to confirm is to match your original part number to one of the interchangeable numbers listed on our product page (such as 25835965, 25844480, etc.). Providing your VIN at checkout guarantees we program it perfectly for your specific vehicle.
