Common Symptoms of a Failing BCM
A faulty Body Control Module can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the likely culprit:

- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Intermittent issues with the radio or instrument cluster displays.
- ✔ The security system acting up, preventing the vehicle from starting (Passlock issues).
- ✔ False warnings on the dashboard, such as ‘door ajar’ lights.

Installation and Post-Install Notes
While installation is straightforward for many DIY mechanics, some post-installation procedures may be required to ensure all systems communicate correctly. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. 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 for correct brake light and traction control operation.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls non-engine related functions. This includes power windows, locks, lights, wipers, security systems, and other comfort and convenience features.
Is this BCM ready to install when I receive it?
Yes, this BCM is programmed to your vehicle’s VIN before we ship it. This makes the installation process much simpler. However, as noted, some vehicles may require additional relearn procedures for the airbag or brake systems, which need a compatible scan tool.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot program and ship the module without it. Your VIN can be found on your vehicle’s dashboard (visible through the windshield) or on your registration and insurance documents.
What happens if my airbag light is on after installation?
This is a known possibility. It means the new BCM needs to be electronically introduced to the vehicle’s airbag module (SDM). A qualified technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
How can I be sure this 2002 Tahoe Body Control Module fits my vehicle?
This module fits a wide range of GM vehicles. The best way to confirm fitment is to match your original part number to one of the numbers listed in our description: 15063578, 15081796, 15095334, 19208537, DKAK, or DPNU.
