Is your 2002 GM truck or SUV experiencing bizarre electrical problems?
The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. It manages everything from your power windows and locks to the interior lights, security system, and instrument cluster warnings. When the BCM starts to fail, it can create a cascade of frustrating and seemingly unrelated issues, making your vehicle unreliable and difficult to diagnose. Don’t let electrical gremlins take your truck off the road. This pre-programmed BCM is the definitive solution to restore full functionality and peace of mind.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following issues, a faulty BCM is the most likely culprit:
- ✔ Erratic interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ Power windows, door locks, or mirrors operating intermittently or not responding.
- ✔ The security system engaging randomly or the ‘Security’ light staying illuminated on the dash.
- ✔ Inaccurate or non-functional gauges on the instrument panel.
- ✔ The radio or climate control system behaving erratically.
- ✔ A ‘No Communication’ error when trying to scan the vehicle with a diagnostic tool.
- ✔ A parasitic battery drain that leaves you with a dead battery overnight.
From the Diagnostic Bay
We recently had a 2002 Yukon XL 1500 come into the shop with a list of complaints that sounded like a poltergeist had taken up residence. The owner reported that the dome lights would randomly turn on while driving, the driver’s side power window had a mind of its own, and the horn would occasionally honk when he used the turn signal. After checking grounds and wiring harnesses, our diagnostics pointed directly to an internal failure in the BCM. Swapping in a pre-programmed module like this one resolved all the issues in under an hour, saving the customer from a costly and time-consuming visit to the dealership.
Plug-and-Play Solution for Your 2002 Yukon BCM
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and hassle out of the repair by pre-programming this module to your vehicle’s specific Vehicle Identification Number (VIN). This ensures that all factory-installed options work correctly right out of the box. Simply provide your VIN during checkout, and we’ll flash the unit with the latest GM software updates before it ships. This process makes our 2002 Yukon BCM a true plug-and-play component, eliminating the need for expensive dealership programming tools.
This module is a direct replacement for the following service numbers: 15063577, 15081857, 19208544, 15095335, DKAJ, and DPNW.

Important Post-Installation Information
While this 2002 Yukon BCM is designed for a straightforward installation, some vehicles may require one or more of the following procedures to ensure all systems are synchronized.
- Airbag System Sync: If the airbag warning light is on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct operation of the brake lights and traction control system.
Please note: Specific procedures can vary by vehicle. We always recommend consulting a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and more.
Is this part difficult to install?
The BCM is typically located under the driver’s side dashboard and is held in by a few bolts and electrical connectors. For someone with basic mechanical skills, the physical replacement is straightforward. The key benefit of our module is that it comes pre-programmed, saving you a trip to the dealer.
What does ‘VIN Programmed’ mean?
It means we load your vehicle’s specific VIN and factory options into the module before we ship it. This ensures the BCM works correctly with the features your truck was built with, making the installation process much simpler.
Do I need to send my old BCM back?
No. This part is sold with no core charge. You can keep your original module.
What if my airbag light is on after I install this BCM?
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to the airbag system (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fix my ‘Service 4WD’ light?
While the BCM can cause a wide range of issues, the ‘Service 4WD’ message is more commonly related to the Transfer Case Control Module (TCCM) or the encoder motor. It’s important to get an accurate diagnosis before ordering parts.
