Post-Installation Information
After installing your new BCM, a couple of additional steps may be required:
- Airbag System Sync: If the airbag warning light is illuminated 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: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What does the Body Control Module do on a 2002 GM truck?
The BCM acts as the brain for most of your truck’s non-engine related electronics. It controls functions like power windows, locks, interior and exterior lighting, the security system, and communicates with other modules in the vehicle.
Is this BCM difficult to install?
The BCM is typically located under the driver’s side of the dashboard, near the steering column. Installation involves disconnecting the battery, removing a few trim panels, and unplugging the electrical connectors to swap the module. It is a manageable job for a DIYer with basic tools.
What information do you need from me?
After your purchase, we require your 17-digit Vehicle Identification Number (VIN). This allows us to program the module specifically for your vehicle’s factory options, ensuring it works correctly right out of the box.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your original module.
What if my airbag light is on after I install this?
This can happen. It means the new BCM needs to be electronically introduced to the airbag system. A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to resolve this.
Will this part fit other GM models?
Yes, this BCM is compatible with a range of 2002 GM trucks and SUVs, including the Tahoe, Suburban, Yukon, Yukon XL, Escalade, and Escalade EXT. Please see the detailed fitment list on this page to confirm for your vehicle.
