Is your 2002 GMC Yukon or GM truck experiencing bizarre electrical issues? You’re not alone.
A failing Body Control Module (BCM) is often the culprit behind a host of frustrating problems, from flickering interior lights and malfunctioning power windows to a vehicle that refuses to start. The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can make your truck feel possessed. This isn’t just an inconvenience; it can be a serious safety and security issue.
This is a direct-fit replacement Body Control Module, compatible with part numbers 15063578, 15081796, 15095334, 19208537, DKAK, and DPNU. We take the guesswork and hassle out of the repair process. Simply provide your vehicle’s VIN during checkout, and we will program the module with the latest official GM software updates specific to your truck. It arrives at your door ready for installation, eliminating the need for an expensive trip to the dealership for programming.
We had a 2002 Sierra 2500 in the shop that was driving the owner crazy. The truck would randomly not start, but the battery, alternator, and starter all tested perfectly. The security light would flash intermittently, and sometimes the radio would stay on after the key was removed. After chasing wires and checking grounds, we pinpointed the BCM. A replacement unit, programmed to the truck’s VIN, solved all the electrical gremlins in one go. These modules control more than you think, and their failure can mimic many other problems.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior dome lights or dashboard lights flickering or staying on.
- ✔ The security system acting erratically or preventing the engine from starting.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Communication errors with other vehicle modules, causing various warning lights.
- ✔ Complete no-start condition with a good battery and starter.
Why Choose Our Pre-Programmed 2002 Yukon BCM?
Replacing a BCM used to require expensive diagnostic tools for post-installation programming. Our solution simplifies this critical repair. By programming the module to your VIN before we ship, we ensure it communicates correctly with your truck’s other systems right out of the box. This saves you time, money, and the headache of coordinating with a repair shop for programming services. This is the most efficient way to restore your vehicle’s functionality and get back on the road with confidence.
Post-Installation Procedures
While our BCM is programmed for your vehicle, some systems may require a ‘handshake’ procedure after installation. This is standard for this type of repair. You may need a professional scan tool to perform the following if you experience related warning lights:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance. No core charge is required; you can keep your old part.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions, such as power windows, locks, interior and exterior lighting, security system, and wipers.
Is this BCM difficult to install?
The physical installation is typically straightforward, involving the removal of a few dash panels and connectors. On a 2002 Yukon, it’s located under the steering column. The main benefit of our product is that the complex software programming is already done for you.
Do I need to send my old BCM back?
No. This purchase has no core charge. You can keep your original module.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to flash the BCM with the exact software and calibrations specified by GM for your truck’s specific options and features, ensuring seamless integration and proper function.
What if my airbag light is on after installation?
This is a known possibility. The new BCM needs to be electronically introduced to the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a compatible high-level scan tool to resolve this.
