Is Your 2002 GM Truck or SUV Experiencing Strange Electrical Issues?
If you’re dealing with flickering interior lights, power windows that won’t cooperate, or a security system that has a mind of its own, you’re likely facing a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement Body Control Module, part number 19208544, is the definitive solution to restore full electrical functionality to your vehicle. We take the guesswork out of the repair by programming the module to your specific Vehicle Identification Number (VIN) before we ship it, ensuring a smoother installation process.
Key Symptoms of a Failing 2002 Suburban BCM
A faulty BCM can manifest in numerous ways, often making diagnosis difficult. If your vehicle is exhibiting any of the following symptoms, a failing BCM is the most likely culprit:
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior dome lights or dashboard lights staying on or not working at all.
- ✔ The security system or anti-theft light flashing, preventing the vehicle from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Communication errors with diagnostic scan tools (U-codes).
- ✔ Inconsistent radio or climate control operation.
From the Diagnostic Bay
We recently had a 2002 Yukon XL come into the shop with a classic BCM failure story. The owner had spent hundreds of dollars replacing the driver’s side master window switch and a door lock actuator, but the problems persisted. The windows would work one day and not the next. After a quick scan, we found multiple communication codes pointing to a network failure. The root cause wasn’t the individual components; it was the BCM failing to properly command them. By installing a VIN-programmed BCM, we resolved all of his electrical gremlins in one go, saving him from further chasing parts and spending unnecessary money.
A Simple, Programmed Solution
Don’t waste time and money at a dealership waiting for programming. Our process is designed for convenience and reliability. Simply purchase this module and provide us with your vehicle’s 17-digit VIN. Our technicians will flash the unit with the latest GM-certified software specific to your vehicle’s options and configuration. This means the module arrives at your door ready for installation. No expensive specialty tools for programming, no trip to the dealer—just a straightforward replacement.
Installation and Post-Install Procedures
The BCM is typically located under the driver’s side of the dashboard, near the steering column. While the physical replacement is straightforward for a DIYer with basic tools, there are a few potential post-installation steps to be aware of:
- Airbag System Sync: In some cases, after installing the new BCM, the airbag warning light may illuminate. This is because the BCM needs to be synced with the SDM (airbag module). A professional scan tool with the ‘Setup SDM Primary Key in BCM’ function will be required to perform this sync and clear the light.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure proper brake light operation and to satisfy the traction control system. This procedure may also require a capable diagnostic tool.
- No Core Charge: You are not required to return your old, faulty module. This saves you the time, hassle, and expense of a core return.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to program this BCM after I receive it?
No. We program the module to the VIN you provide before we ship it. It arrives ready for installation, saving you a trip to the dealership.
Where is the BCM located on my 2002 Suburban or Tahoe?
The Body Control Module is located under the driver’s side dashboard, typically attached to a bracket near the steering column.
What is a core charge, and do I have to send my old part back?
A core charge is a deposit you pay until you return your old part. This module has NO core charge, so you can keep your original BCM without any extra fees or hassle.
Will this fix my ‘Service Security System’ light?
A faulty BCM is a very common cause of security system issues, including a persistent warning light or a no-start condition. While this module will resolve BCM-related security faults, it’s essential to ensure your vehicle has been properly diagnosed, as other components like the ignition switch can also cause similar symptoms.
What if my airbag light is on after I install the new BCM?
If the airbag light appears, it means the new BCM needs to be electronically introduced to the vehicle’s airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to resolve this.
Which part numbers does this module replace?
This BCM is a direct replacement for the following service numbers: 15063577, 15081857, 19208544, 15095335, DKAJ, and DPNW.
