Restore Full Electronic Control to Your GM Truck or SUV
Are the electronics in your 2000 GMC Yukon, Chevy Tahoe, or Suburban acting erratically? Power windows that won’t respond, interior lights with a mind of their own, or a security light that leaves you stranded are all classic signs of a failing Body Control Module (BCM). This central computer is the nerve center for your vehicle’s comfort and convenience features, and when it fails, it can cause a cascade of frustrating electrical problems. Don’t let a faulty module compromise your vehicle’s reliability and function.
Common Symptoms of a Failing BCM
- ✔ Inoperative power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting behavior (flickering, staying on, or not working at all).
- ✔ Security system faults or a persistent anti-theft light that prevents the engine from starting.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire.
- ✔ False warning messages appearing on the instrument cluster.
- ✔ Unexplained and rapid battery drain (parasitic draw) when the vehicle is off.
- ✔ Wipers or radio functioning incorrectly.
From the Diagnostic Bay
We had a 2000 Tahoe come in with a battery that would die every two days. The owner had already replaced the battery and alternator, with no success. After performing a parasitic draw test, we pinpointed the BCM. It wasn’t fully entering its ‘sleep mode’ when the truck was turned off, causing a slow but relentless drain. Installing a properly programmed BCM didn’t just fix the strange electrical glitches the owner had learned to live with; it solved the phantom battery drain that was costing him time and money. It’s a prime example of how a failing BCM can manifest in ways beyond just non-working accessories.
The Simple, Reliable Solution: A VIN-Programmed Module
This replacement Body Control Module is the definitive solution to restore your vehicle’s functionality. We eliminate the biggest hurdle in this repair by pre-programming the module with the latest official GM software, specifically matched to your vehicle’s unique VIN. This critical step ensures that all your factory-installed options—from power seats to the specific lighting package—work correctly right out of the box, saving you a costly trip to the dealership.
Why Our Programmed 2000 Yukon XL BCM is the Best Choice
Choosing our module is about convenience and confidence. A dealership repair often requires you to have your vehicle towed in for installation and programming, leading to high labor costs and significant vehicle downtime. Our service empowers you to perform the physical swap yourself or at your trusted local shop. We handle the complex programming beforehand, making the process as straightforward as possible.
- VIN-Specific Programming: Arrives flashed with your vehicle’s exact configuration for a seamless integration.
- Latest GM Software: Loaded with the most current updates for enhanced stability and performance.
- No Core Charge: Keep your old module. There’s no need to worry about shipping anything back to us.
- Direct-Fit Replacement: Engineered to replace OEM part numbers 9377486, 16257155, 15136876, and 09377486.
Installation and Post-Install Procedures
The BCM is located on the driver’s side, under the dashboard. After disconnecting the battery, the physical installation involves unplugging the electrical connectors and removing a few mounting fasteners. Once the new module is installed and the battery is reconnected, your vehicle should start and run. However, a couple of additional synchronization steps may be necessary to ensure all systems communicate correctly.
Potential Post-Installation Steps:
- Airbag System Sync: If the airbag warning light is on after installation, a scan tool procedure called ‘Setup SDM Primary Key in BCM’ is required. This syncs the new BCM with the airbag system, which is a critical safety step.
- Brake Pedal Position Relearn: In some cases, the brake pedal position sensor may need to be recalibrated to ensure correct brake light and traction control operation.
Please note: While many installations are seamless, access to a professional-grade diagnostic tool may be required to complete these final synchronization procedures. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that supervises many of your vehicle’s non-engine related functions. This includes power windows, door locks, interior and exterior lighting, the security system, and communication between other onboard modules.
Why is providing my VIN so important?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and options your truck or SUV was built with. This step is crucial for ensuring everything works correctly and avoids compatibility issues after installation.
Can I install this module myself?
Yes, the physical replacement is straightforward for someone with basic mechanical skills. However, be aware that post-installation procedures, like syncing the airbag system, may require a professional scan tool that most DIY mechanics do not own.
What happens if I don’t perform the airbag sync procedure?
If the airbag light is on after installation and the sync procedure is not performed, the airbag system will be inoperative. It is a critical safety step that must be completed to ensure the system is ready to function in an emergency.
Is this a plug-and-play part?
It is as close to plug-and-play as possible. Because we pre-program it to your VIN, it eliminates the most complex step. While many vehicles will work perfectly after installation, some may require the additional relearn procedures mentioned to clear warning lights or restore full function to all systems.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
