He loses half a day of work and has to pay for a tow, all because the BCM is failing. The issue isn’t mechanical; it’s the electronic brain that controls body functions.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle responsible for managing and monitoring various electronic accessories and body functions that are not related to the engine. This includes power windows, locks, interior/exterior lighting, security systems, and climate controls.
Is this BCM truly “plug and play”?
This module is pre-programmed to your VIN, which handles the most difficult part of the installation. However, depending on your specific vehicle, you may need to perform simple, tool-free relearn procedures after installation, such as the Brake Pedal Position Relearn. In some cases, if the airbag light is on, a professional scan tool is required to sync the airbag system. These are standard GM procedures for this type of repair.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield.
What happens if I don’t perform the required relearn procedures?
Failing to perform necessary post-installation procedures can result in certain features not working correctly. For example, not performing the Brake Pedal Position Relearn could lead to improper brake light operation. If the airbag light is illuminated, the system will not be active until it is properly synced with the new BCM.
What part numbers does this module replace?
This BCM is a direct replacement for a range of part numbers, including 15167329, 15194169, 15747545, 15136224, 15116065, 15198115, 15136876, and 10367689. Please verify your part number or contact us to confirm fitment.
