Restore Full Electrical Function to Your GM Truck or SUV
If you’re battling bizarre electrical issues in your 2000 Suburban, Tahoe, or Yukon—like power windows with a mind of their own, flickering interior lights, or a security light that won’t turn off—you’re likely dealing with a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating problems. This isn’t just an inconvenience; it can affect vehicle security and safety systems. This replacement 2000 Suburban 2500 BCM is the reliable, straightforward solution to get your truck back to 100%.
We take the guesswork and high dealership costs out of the equation with our professional cloning service. Simply send us your original BCM, and we will transfer all of its critical data—including key fob programming, mileage, and vehicle-specific options—to this replacement unit. It arrives at your door, ready for plug-and-play installation, with the latest GM software updates already applied based on your VIN. No expensive trips to the dealer for programming are required.
From the Diagnostic Bay: The Case of the Confused Tahoe
A customer brought in a 2000 Tahoe a while back with a laundry list of complaints: the radio would turn on and off, the power locks worked intermittently, and the security light was always on, sometimes preventing it from starting. They had already replaced the battery and checked the fuses. In my shop, I’ve seen this exact pattern dozens of times on these GMT800 platforms. A quick scan showed communication errors with the BCM. The internal circuitry, specifically the solder joints on the main board, often develops micro-fractures over two decades of heat cycles and vibration. We performed our cloning service onto a replacement BCM, and within an hour of installation, every single electrical gremlin was gone. It’s a classic failure, and this is the definitive fix.
Is Your GM Truck Showing These BCM Failure Signs?
- ✔ Erratic or non-functional power windows and door locks.
- ✔ Interior dome lights or dashboard lights staying on or not working at all.
- ✔ The security or anti-theft light is illuminated, potentially causing a no-start condition.
- ✔ Horn honking unexpectedly or the alarm system malfunctioning.
- ✔ Radio or climate control systems behaving unpredictably.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), such as U-codes (e.g., U1000, U1016), stored in the system.
- ✔ Inconsistent operation of remote keyless entry (RKE) fobs.
A Straightforward Guide to BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On these 2000 GM models, the BCM is located under the driver’s side of the dashboard, typically to the left of the steering column. You may need to remove a lower dash panel for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your newly cloned BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- ✔ Reconnect Power: Re-attach the negative battery terminal.
- ✔ Test and Verify: Start the vehicle and test all body functions: power windows, locks, radio, interior lights, and wipers. Check the dashboard for any warning lights.
Important Post-Installation Steps
While this module is cloned for a simple installation, GM’s complex systems may require a couple of final sync procedures. These are not always necessary but are important to be aware of:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible high-level scan tool. This re-establishes communication between the airbag and body modules.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be needed to ensure correct brake light and traction control operation. This also typically requires a professional diagnostic tool.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
How does the cloning service work?
After your purchase, you’ll ship your original BCM to us. We use specialized equipment to perform a full data transfer from your old module to the replacement unit. This copies all vehicle-specific settings, security information, and options, making the new module a perfect electronic match for your truck.
Do you keep my old BCM?
No. We always return your original module along with the newly programmed replacement. We do not require a core and believe you should keep your original parts.
Will I need to get my keys reprogrammed?
No. Because we clone your original data, the replacement BCM will recognize your existing keys and key fobs automatically. This is a major benefit that saves you time and money.
What tools do I need for installation?
Basic hand tools are usually all that’s required, such as a socket set and a small pry tool for dash panels. No special electronic tools are needed for the physical installation.
What if the airbag light comes on after I install it?
This can happen occasionally as the vehicle’s computers re-sync. It requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be done by any professional mechanic with a high-level diagnostic scan tool.
Is this a direct replacement for other part numbers?
Yes, this module with part number 9377486 is a direct, compatible replacement for modules with part numbers 16257155, 15136876, and 09377486.
