Are you dealing with baffling electrical issues in your 2002 GM truck or SUV? Problems like flickering lights, malfunctioning power windows, or a security system that has a mind of its own are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and seemingly unrelated symptoms. This replacement Body Control Module, part number 19208544, is the definitive solution to restore your vehicle’s electronic functions to factory-perfect condition.
From the Diagnostic Bay
We had a 2002 Yukon XL come into the shop with a list of complaints that sounded like a poltergeist was at work. The radio would change stations on its own, the interior lights would stay on, and the horn would chirp randomly when locking the doors. The owner had already replaced the battery and checked all the fuses. After a quick scan, we saw multiple communication errors pointing towards the BCM. Instead of a complex and costly wiring chase, we installed a VIN-programmed BCM. In under an hour, every single ghost in the machine was gone. It’s a reminder that sometimes the most complex-sounding problems have a single, straightforward solution.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, mirrors, and door locks.
- ✔ Interior dome lights or exterior lamps staying on or not turning on at all.
- ✔ The security light is illuminated on the dashboard, or the alarm system acts up.
- ✔ Horn not working or sounding randomly.
- ✔ Windshield wipers behaving erratically (won’t turn off, intermittent issues).
- ✔ Instrument cluster displaying incorrect information or false warning lights.
- ✔ Communication issues with diagnostic scan tools.

Installation & Post-Install Notes
This BCM is located under the steering column and is a direct-fit replacement. While the physical installation is straightforward for a DIYer with basic tools, please be aware of potential post-installation procedures:
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems.
- Brake Pedal Position Relearn: A brake pedal position sensor relearn might be necessary to ensure proper brake light and traction control operation.
We always recommend consulting a factory service manual or a qualified technician if you are unsure about any part of the installation process.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories like power windows, lights, security systems, wipers, and door locks. It acts as a central hub for these functions.
Do I need to program this module?
No. We program the module to your vehicle’s VIN before shipping it to you. This makes the installation process much simpler and avoids a costly trip to the dealership for programming.
Where is the BCM located on my 2002 Tahoe/Yukon/Avalanche?
The BCM is typically located under the driver’s side of the dashboard, near the steering column. It is a black plastic box with several large electrical connectors.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) contains specific information about the options and features your truck was built with. We use the VIN to load the exact correct software and settings onto the BCM, ensuring it works perfectly with your vehicle.
What if my airbag light is on after I install the new BCM?
If the airbag light comes on, it means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by any professional mechanic with a compatible bi-directional scan tool.
Is there a core charge?
No, there is no core charge on this item. You can keep your old part.
