Is Your 2000 GM SUV Plagued by Electrical Gremlins?
If you’re experiencing a frustrating array of electrical issues in your 2000 GMC Yukon, Yukon XL, Chevy Tahoe, or Suburban, the root cause is often a failing Body Control Module (BCM). This module is the central nervous system for your vehicle’s body electronics, controlling everything from the power windows and door locks to the interior lights and security system. When it begins to fail, it can create a cascade of bizarre and unpredictable problems that can be difficult to diagnose.
From the Diagnostic Bay
We had a 2000 Tahoe come in that was driving the owner crazy. The dome lights would randomly turn on while driving at night, the power locks would cycle on their own, and the radio would shut off unexpectedly. He’d already replaced the battery and checked all the fuses. After connecting our scan tool, we saw a dozen communication error codes all pointing to one culprit. We swapped in a pre-programmed BCM, and instantly, all the gremlins vanished. It’s amazing how this one module can cause so much chaos when it fails.

Common Symptoms of a Failing BCM
- ✔ Erratic power windows or door locks that work intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or refusing to turn on.
- ✔ The anti-theft or security system acting up, causing a no-start condition (blinking ‘Security’ light).
- ✔ Gauges on the instrument cluster behaving strangely, sweeping randomly, or not responding.
- ✔ Radio, stereo, or climate control malfunctions.
- ✔ False warning lights appearing on the dashboard for various systems.
- ✔ The horn honking unexpectedly or not working when pressed.
Installation and Post-Install Notes
The BCM is typically located under the driver’s side dashboard. While the physical installation is straightforward, please be aware of a few potential post-installation procedures that may be necessary depending on your specific vehicle’s configuration:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system and must be performed with a professional-grade bidirectional scan tool.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration might be needed to ensure proper operation of the brake lights and traction control system.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it to you. It arrives ready for installation, saving you time and the high cost of dealership programming.
Where is the BCM located on my 2000 Yukon or Tahoe?
The Body Control Module is located on the driver’s side, up under the dashboard, typically to the left of the steering column.
Do I have to return my old, faulty BCM?
No. This purchase comes with no core charge. You can keep your original module without any additional fees or hassle.
What if my airbag light comes on after I install the new BCM?
This can happen occasionally. It means the new BCM needs to be electronically synced with your vehicle’s airbag module (SDM). The procedure is called ‘Setup SDM Primary Key in BCM’ and requires a professional scan tool to complete.
Will this fix the ‘Security’ light and no-start problem?
Yes, a faulty BCM is one of the most common causes of a persistent ‘Security’ light and the resulting no-start condition in these GM trucks. This pre-programmed module has the correct information to resolve that issue.
