Guided Installation for a Confident Fix
Replacing your 2000 Yukon XL 1500 PCM is a straightforward job you can tackle with basic hand tools. Our goal is to empower you to complete the repair yourself, saving you time and a costly trip to the shop. Follow these steps for a successful installation:
- Safety First: Begin by disconnecting the negative terminal of your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On your Yukon XL, the PCM is typically located in the engine bay on the driver’s side, underneath the battery tray. You will need to remove the battery to access it.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old PCM. They have locking tabs that need to be released. Once disconnected, unbolt the module from its mounting bracket.
- Install the New PCM: Mount your new, pre-programmed module in the same location. Securely reconnect the color-coded electrical harnessesโthey will only fit in their correct positions.
- Reconnect Power: Re-install the battery and connect the negative battery terminal.
- Perform Security Relearn: Your vehicle’s anti-theft system may need to be synchronized with the new PCM. This simple procedure, often called a ‘security relearn,’ typically involves turning the key to the ‘ON’ position for 10-15 minutes. Consult your owner’s manual for the exact steps for your model.
A Mechanic’s Notebook: The Diagnostic Dead End
“A customer brought in a 2000 Sierra with the same platform, completely stumped. He’d replaced spark plugs, ignition coils, and even a throttle position sensor trying to fix a rough idle and stalling issue. The codes were intermittent and misleading. After confirming his fuel pressure and ignition system were healthy, we looked at the command centerโthe PCM. A quick swap with one of our pre-programmed units solved everything instantly. It’s a powerful reminder that sometimes the ‘brain’ is the source of the problem, and a direct replacement is the fastest path back to reliability.”

Frequently Asked Questions
What does ‘programmed to my VIN’ mean?
It means we load the module with the specific software and calibrations from General Motors that match your vehicle’s exact features, such as engine size, transmission type, and emissions equipment. This ensures seamless integration and optimal performance without requiring a trip to the dealership for expensive programming.
Do I need to do anything after installation?
After installing the PCM and reconnecting the battery, you will likely need to perform a simple ‘Security Relearn Procedure’. This syncs the new module with your vehicle’s anti-theft system and can usually be done in your driveway in about 15 minutes with just your ignition key.
Where is the PCM located on my 2000 Yukon XL?
The Powertrain Control Module is located in the engine compartment on the driver’s side. It is mounted to a bracket directly underneath the battery and its tray. You will need to remove the battery to gain access for the replacement.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We must have your VIN to program the module before we can ship it to you.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM (common codes include P0600-P0606), this replacement unit is the correct solution. However, a check engine light can be caused by many other components. It’s always best to have the codes read to help confirm the diagnosis.
