Restore Your GM Truck’s Electrical System with a Plug-and-Play BCM
Are you tired of chasing electrical gremlins in your 2000 GMC Yukon or compatible GM truck? Flickering lights, erratic gauges, power windows with a mind of their own, or a security light that won’t turn off are classic signs of a failing Body Control Module (BCM). This isn’t just an annoyance; it’s a core system failure that can affect your vehicle’s drivability and security. This replacement BCM is the definitive solution, arriving at your door pre-programmed with the latest GM software updates specifically for your truck’s VIN.
A Technician’s Notebook: The Case of the Haunted Silverado
I remember a 2000 Silverado 1500 that came into my bay with a laundry list of bizarre symptoms. The owner said his interior lights would pulse randomly, the radio would shut off, and sometimes the truck wouldn’t start, showing only a security light. He’d already replaced the battery and checked the grounds. A scan showed a dozen intermittent U-codes, pointing to a network communication breakdown. The culprit? A failing BCM, part number 9385236. Once we installed a VIN-programmed module, every single one of those ghostly electrical issues vanished. It’s a fix I’ve performed hundreds of times on these otherwise bulletproof GM trucks.
Is Your Truck Showing These Symptoms?
A faulty BCM can cause a wide range of issues that might seem unrelated. If you’re experiencing any of the following, this module is likely the solution you need.
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security or anti-theft light stays illuminated, causing a no-start condition.
- ✔ Erratic or dead instrument cluster gauges.
- ✔ False warnings on the driver information center (DIC).
- ✔ Communication error codes, such as U0140, when scanned with a diagnostic tool.
- ✔ The radio or climate control system behaves erratically.
The Smart Solution: Pre-Programmed and Ready to Install
The biggest hurdle in replacing a BCM has always been the expensive and time-consuming trip to the dealership for programming. We eliminate that step entirely. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash this module with the correct, updated GM software for your specific vehicle. This ensures all factory-intended functions work correctly right out of the box, saving you hundreds in dealer fees and getting your truck back to perfect working order faster. Plus, with no core charge, you don’t have to worry about the hassle of sending your old, faulty part back.
A Straightforward Guide to Installation
Replacing the 2000 Yukon BCM is a job most DIY enthusiasts can handle with basic tools. The module is typically located under the driver’s side of the dashboard.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On most of these trucks and SUVs, you’ll find it attached to a bracket 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. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM onto the bracket and securely plug in all the electrical connectors. You’ll hear a click as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test your lights, locks, windows, and other body functions to confirm the repair.
Important Post-Installation Steps
While this module is programmed for your VIN, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If your 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 relearn may be required to ensure proper brake light and traction control operation. This also requires a compatible diagnostic tool.
Disclaimer: Always consult a factory service manual or a qualified technician if you are unsure about any step. Specific procedures can vary slightly by vehicle model.

Frequently Asked Questions
Do I need to send my old BCM back?
No. This purchase comes with no core charge, so you can keep your original module. This saves you time and return shipping costs.
What information do you need to program the module?
After you place your order, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We use this to load the precise GM software and calibrations for your truck’s specific options.
Is this a difficult part to install myself?
The physical replacement is straightforward for most DIYers with basic hand tools. However, be aware that post-installation procedures like an airbag system sync or brake pedal relearn may be necessary and require a professional-grade scan tool.
Will this fix my ‘Security’ light and no-start problem?
Yes, a failing BCM is one of the most common causes of a persistent security light and a crank-no-start condition on these GM vehicles. This programmed module is designed to resolve that issue by correctly communicating with your vehicle’s anti-theft system.
What if the part number on my old module is 9371990?
This module is fully compatible and serves as a direct replacement for service numbers 9385236, 9371990, and 19208539. It will function identically once programmed to your VIN.
