Installation and Post-Install Considerations
Replacing the BCM is a straightforward job for the average DIYer. It is typically located under the steering column or behind the center dash panel. After swapping the part, you may need to perform a couple of simple procedures depending on your vehicle’s configuration:
- Airbag System Sync: If the airbag light remains on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
This part comes with a one-year warranty and requires no core charge, so you can keep your old part without any hassle.
Frequently Asked Questions
What does a Body Control Module do on a 2003-2006 Tahoe?
The BCM acts as the central computer for your Tahoe’s body electronics. It controls non-engine related functions like power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC system.
Will I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s specific VIN before shipping. This ensures it is ready for immediate installation and operation, saving you time and money.
Is this part difficult to install?
Installation is generally simple and can take as little as 5-10 minutes. The BCM is usually located under the driver’s side dash near the steering column. Simply disconnect the battery, unclip the wiring harnesses, swap the module, and reconnect everything.
What should I do if my airbag light turns on after installing the new BCM?
If the airbag light is on, it means the new BCM needs to be synchronized with the vehicle’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
How can I be sure my BCM is the problem?
While a professional diagnosis is always best, common signs of a failing BCM include multiple, unrelated electrical issues. If your power locks, windows, lights, and HVAC are all acting up, the BCM is a very likely cause.
