Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system.
Is this module really plug-and-play?
Yes. We use the VIN you provide during checkout to program the module with your vehicle’s specific software and settings. This ensures it communicates correctly with your other onboard computers right out of the box, eliminating the need for a trip to the dealership for programming.
What if my airbag light comes on after installation?
In some cases, the new BCM may need to sync with the airbag system (SDM). If the airbag light appears, a technician will need to perform a simple ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. This is a quick sync and not a full reprogramming.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your old module, which saves you the time and hassle of return shipping.
Where is the BCM located on my truck?
On most compatible models like the Sierra, Silverado, and Tahoe, the BCM is located under the driver’s side dashboard, near the steering column. Installation typically takes less than 15 minutes with basic tools.
Will this fix my specific electrical problem?
This programmed GM 15116066 BCM is the direct solution for the most common electrical failures associated with this module, such as erratic lights, locks, windows, and HVAC issues. It is designed to restore these systems to factory operation.
