Programmed 2001 Yukon XL 1500 BCM 19180223 | VIN-Matched | Plug & Play

Tired of Chasing Electrical Gremlins in Your GM Truck?

If you’re dealing with bizarre electrical issues in your 2001 GMC or Chevy truck—like power windows with a mind of their own, door locks that don’t respond, a security light that stays on, or an intermittent no-start condition—you’re not alone. These frustrating problems often point to a single culprit: a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, when the BCM starts to fail, it can create a cascade of confusing and unpredictable symptoms. This isn’t just an annoyance; it can affect your vehicle’s security and daily usability.

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 the likely solution:

• ✔ Power windows, mirrors, or door locks working intermittently or not at all.
• ✔ The security or anti-theft light stays illuminated, preventing the engine from starting.
• ✔ Interior or exterior lights flickering, staying on, or not turning on.
• ✔ The radio or instrument cluster behaves erratically.
• ✔ False warnings on the driver information center (e.g., “Door Ajar”).
• ✔ Communication error codes (U-codes) when scanned with a diagnostic tool.

The Simple, Reliable Solution: A VIN-Programmed BCM

Forget expensive dealership visits and the hassle of finding a shop that can program a new module. We take the guesswork out of the repair. When you order this 2001 Yukon XL 1500 BCM, you provide us with your vehicle’s VIN. Our technicians then program the module with the latest official GM software specific to your truck’s configuration. It arrives at your door ready to be installed, saving you hundreds in programming fees and vehicle downtime. Plus, there is no core charge, so you can keep your old part.

A Straightforward Guide to Installation

Replacing the BCM is a job most DIYers can handle in under an hour with basic hand tools. It’s located under the driver’s side of the dashboard.

1. Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
2. Locate the BCM: On most of these GM trucks, the BCM is mounted to the left of the steering column, often behind a lower dash panel. You may need to remove a plastic trim piece for access.
3. Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module from its bracket and remove it.
4. Install the New Module: Mount your new, pre-programmed BCM in the same location. Reconnect all the electrical connectors, ensuring they click securely into place.
5. Reconnect Power: Re-attach the negative battery terminal.
6. Perform Post-Install Checks: Start the vehicle and test all body functions—windows, locks, lights, and radio. Refer to the post-installation procedures below if any warning lights appear.

Important Post-Installation Steps

While our programming handles the heavy lifting, some vehicle systems may need to be re-synced after the new BCM is installed.

• Airbag System Sync: If your airbag warning light is on after installation, a simple procedure called “Setup SDM Primary Key in BCM” is required. This syncs the airbag system with the new BCM and must be done with a professional-grade scan tool.
• Brake Pedal Position Relearn: In some cases, the brake pedal position sensor may need to be recalibrated to ensure your brake lights and traction control system function correctly. This is also performed with a scan tool.

Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.
