Restore Full Control Over Your Truck’s Electronics
Are you chasing down frustrating electrical gremlins in your 2000 GM truck or SUV? Flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body accessories, and when it fails, it can cause a wide range of confusing and intermittent problems. This replacement BCM is the direct, reliable solution to restore your vehicle’s functionality and your peace of mind.
We make the repair process simple. Unlike going to a dealership, which involves high costs and lengthy service appointments, our BCM arrives at your door pre-programmed for your specific vehicle. Simply provide us with your Vehicle Identification Number (VIN) during checkout, and our technicians will flash the module with the latest official GM software. This ensures perfect communication between the BCM and your truck’s other systems right out of the box.
A Technician’s Notebook
I remember a 2000 Yukon that came into the shop with a laundry list of bizarre symptoms. The owner complained of the radio turning off randomly, the dome lights not working, and an intermittent no-start condition with the security light flashing. We scanned for codes and found a slew of ‘loss of communication’ errors (U-codes) pointing to the BCM. After confirming power and ground to the module were good, we knew the internal logic had failed. Swapping in a VIN-programmed BCM like this one solved every single issue in under an hour. It’s a common failure on these GMT800 platforms, and a pre-programmed module is the most efficient fix.
Is Your Truck Showing These Symptoms?
A faulty BCM can manifest in many ways. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ Intermittent or non-working power windows, door locks, and mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ The security or anti-theft system light is illuminated, preventing the engine from starting.
- ✔ Gauges on the instrument cluster behaving erratically or not working at all.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U1000.
- ✔ Remote keyless entry (RKE) system is unresponsive.
A Straightforward Guide to Installation
Replacing the BCM is a job most DIYers can handle with basic tools. This module is designed for a direct fit, getting you back on the road quickly.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the systems to discharge.
- Locate the BCM: On these models, the BCM is typically located under the driver’s side of the dashboard, to the left of the steering column.
- Remove Connectors: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed.
- Swap the Module: Unbolt or unclip the old BCM from its mounting bracket and install the new module in its place.
- Reconnect Everything: Plug the electrical connectors firmly into the new BCM and reconnect the negative battery terminal.
Post-Installation Notes
While this BCM is programmed for your VIN, some vehicles may require additional steps after installation:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation.
- Disclaimer: Always consult a factory service manual or a qualified technician if you are unsure about any procedure.

Frequently Asked Questions
Do I need to program this 2000 Tahoe BCM?
No. We program the module to your vehicle’s VIN before shipping it to you. It arrives ready for installation, saving you a trip to the dealership.
Where is the BCM located on my 2000 Tahoe or Suburban?
The Body Control Module is located inside the cabin, under the driver’s side dashboard, typically to the left of the steering column.
Is there a core charge for this part?
No, there is no core charge. You can keep your original, non-working module without needing to send it back.
What if my airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag module. A mechanic with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
What happens after I place my order?
After you purchase the BCM, you will need to send us your vehicle’s 17-digit VIN. Our technicians will use this to program the module with the latest GM software before we ship it out.
