Restore Full Electrical Function to Your GM Truck or SUV
Are you battling bizarre and frustrating electrical issues in your 2000 GM truck or SUV? Flickering lights, malfunctioning power windows, or random warning messages on your dash are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing problems. This replacement BCM is the definitive solution to restore your vehicle’s proper operation and your peace of mind.
This isn’t just a part; it’s a complete, ready-to-install solution. We take the hassle and expense out of the repair by programming the module to your vehicle’s specific VIN before it ships. This means you can bypass a costly trip to the dealership for programming. Simply provide your VIN at checkout, and we’ll handle the rest, ensuring the BCM integrates seamlessly with your vehicle’s existing systems.
From the Diagnostic Bay
We had a 2000 Yukon come in with a complaint the owner called ‘haunted’. The horn would chirp randomly, the interior lights would fade in and out while driving, and the ‘Service 4WD’ light was on, even though the 4×4 system seemed to work fine. After hours of chasing wires, we traced all the faults back to a single point of failure: the BCM. A failing module was sending corrupt data across the vehicle’s network, causing chaos. Installing a VIN-programmed BCM like this one resolved all the issues instantly, saving the customer from replacing perfectly good switches and sensors.
Diagnosing and Replacing Your 2000 Suburban BCM
A faulty BCM can be difficult to diagnose because its symptoms often mimic other problems. If you’re experiencing several of the issues below, your Body Control Module is the likely culprit. This module is a direct-fit replacement for part number 9377486 and other interchangeable numbers, designed to get your truck back to 100%.
Common Symptoms of a Failing BCM:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not turning on at all.
- ✔ The security system acting up, preventing the vehicle from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Inaccurate gauge readings or warning lights on the instrument cluster (e.g., ‘Service 4WD’).
- ✔ Problems with the radio or climate control system operation.
Installation and Post-Install Procedures
While the module arrives programmed for your vehicle, some systems may require a ‘handshake’ with the new BCM after installation. This is a normal part of the process. Specifically, be aware of the following potential procedures which may require a professional-grade scan tool:
- Airbag System Sync: If the airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control functionality.
This module is a direct replacement for the following part numbers: 16257155, 15136876, 09377486, 9377486.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We program the module to your vehicle’s VIN before we ship it to you. This saves you time and the expense of dealer programming. Just provide your VIN during or after your purchase.
Where is the BCM located on my 2000 Suburban or Tahoe?
The Body Control Module is typically located under the driver’s side of the dashboard, to the left of the steering column. It’s a black plastic box with several large electrical connectors.
What if my airbag light turns on after I install this?
This can happen. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a professional diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Is this a simple plug-and-play installation?
For the most part, yes. The module is physically plug-and-play and is pre-programmed. However, as noted, certain models may require additional relearn procedures for the airbag or brake systems, which require a specific scan tool.
Will this fix my ‘Service 4WD’ light?
If the ‘Service 4WD’ light is being caused by a communication error from a faulty BCM, then yes, this part will resolve that issue. However, if there is a separate mechanical or sensor issue with your 4WD system, that will need to be addressed separately.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module.
