Restore Full Electrical Function to Your 2002 GM Truck or SUV
Are you battling frustrating and unpredictable electrical problems in your 2002 GMC Yukon, Tahoe, Escalade, or another compatible GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, or a persistent security light are often symptoms of a failing Body Control Module (BCM). The BCM acts as the central command center for your truck’s body electronics. When it fails, it can create a cascade of seemingly unrelated problems. This replacement Body Control Module, part number 15081857, is the definitive solution to restore your vehicle’s proper operation and reliability.
Unlike a standard replacement part from a dealership or parts store, this BCM comes with a crucial service: it is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This means we load the latest, most stable software updates from GM, ensuring optimal performance and compatibility. This pre-programming service saves you a costly trip to the dealer and eliminates the need for expensive proprietary scan tools for initial setup, making the replacement process as smooth as possible.
From the Diagnostic Bay
We recently had a 2002 Escalade in the shop with a classic BCM failure case. The customer complained that the power door locks would cycle randomly while driving, the interior dome lights would stay on, and the radio would sometimes not power off after removing the key. They had already replaced the battery and checked every fuse with no success. After connecting our diagnostic tool, we found multiple communication error codes pointing to the BCM. Installing a pre-programmed 2002 Yukon Body Control Module like this one resolved every single issue in one go. It’s a reminder that what seems like multiple small problems is often one central failure.
Why Choose a VIN-Programmed BCM?
The BCM is not a simple plug-and-play component. It communicates with nearly every other module in your vehicle, from the Engine Control Module (ECM) to the airbag system (SDM). It needs to know the specific options your vehicle was built with—such as power seats, sunroof, or specific lighting packages—to function correctly. Our programming service ensures that the module you receive is a perfect electronic match for your truck, right out of the box.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off, or that flicker intermittently.
- ✔ The “SECURITY” light on the dashboard is illuminated, potentially causing a no-start condition.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Inaccurate readings on the instrument cluster’s information display.
- ✔ Problems with the HVAC (heating and air conditioning) controls.
- ✔ The radio or other accessories staying on after the key is removed.
Installation and Post-Install Considerations for Your 2002 Yukon Body Control Module
The BCM is typically located under the driver’s side of the dashboard, near the steering column. Physical installation involves disconnecting the battery and carefully swapping the electrical connectors from your old module to the new one. While the unit is programmed for your vehicle’s main functions, certain safety and auxiliary systems may require a recalibration or synchronization procedure after installation.
Important Post-Installation Steps:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade diagnostic tool. This syncs the new BCM with the airbag module.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to satisfy the traction control system.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module do on a 2002 Yukon?
The BCM is a computer that manages and controls most of your vehicle’s non-engine related electronic functions. This includes power windows, locks, interior and exterior lighting, the security system, warning chimes, and communication between various other electronic modules.
Is this BCM difficult to install?
The physical replacement is straightforward for someone with basic mechanical skills, as it’s typically held in with a few bolts or clips under the dashboard. However, post-installation procedures like the Airbag System Sync or Brake Pedal Position Relearn may require a professional scan tool that most DIY mechanics do not own.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to access the specific build data for your truck from GM’s database. We use this information to program the BCM with the correct software and settings for your exact options, ensuring it works correctly once installed.
What happens if I don’t perform the post-installation procedures?
If a required procedure is not performed, you may have lingering issues. For example, if the airbag system sync is needed and not done, the airbag warning light will stay on, and the system may not function correctly in an accident. It is critical to address any warning lights that appear after installation.
Is there a core charge for this part?
No, there is no core charge for this module. You can keep your original part without needing to send it back to us.
