Installation and Post-Install Procedures
Installation is straightforward. The BCM is typically located under the driver’s side dashboard, near the steering column. In most cases, it’s a simple plug-and-play swap that takes just a few minutes. However, please be aware of the following potential post-installation steps:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a technician must perform the “Setup SDM Primary Key in BCM” procedure using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
There is no core charge for this part, so you can keep your old module without the hassle of returning it.
Frequently Asked Questions
What does a Suburban 1500 Body Control Module do?
The BCM is a computer that manages many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and the HVAC system. It’s essential for driver and passenger comfort and convenience.
Is this BCM ready to install out of the box?
Yes! This module is pre-programmed to your vehicle’s VIN before it ships. This makes installation a simple plug-and-play process, with no need for additional dealership programming for most functions.
What happens if I install a BCM that isn’t programmed?
An unprogrammed BCM will not work correctly. It won’t have your vehicle’s specific options and security information, leading to feature malfunctions, a no-start condition, or persistent warning lights. VIN programming is essential for proper operation.
Will this fix my airbag light?
If the airbag light is on due to a faulty BCM (like with code B1001), this part will resolve the root cause. However, after installation, the system must be re-synced using the ‘Setup SDM Primary Key in BCM’ procedure with a proper scan tool to turn the light off.
Do I need to send my old part back?
No, there is no core charge on this module. You can keep your old part or dispose of it responsibly without any extra fees or hassle.
Where is the BCM located on a 2009 Suburban 1500?
The BCM is located inside the cabin, under the driver’s side of the dashboard, typically to the left of the steering column.
