Frequently Asked Questions
What exactly does the PCM do?
The Powertrain Control Module (PCM) is the main computer that controls your GMC Yukon’s engine and transmission. It takes data from sensors all over the vehicle to manage fuel injection, ignition timing, emissions systems, and automatic transmission shift points to ensure optimal performance, fuel economy, and low emissions.
Is this part difficult to install?
The physical installation is straightforward for anyone with basic mechanical skills. It’s typically located under the hood on the driver’s side, near the battery. After swapping the hardware, you will need to perform a simple security relearn procedure, which does not require any special tools. We recommend disconnecting the battery before starting work.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents. We cannot ship your part until we receive the VIN.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the PCM (verified by codes like P0601 or a professional diagnosis), then this 2001-2002 GMC Yukon PCM 12200411 is the correct solution. However, it’s crucial to ensure the issue isn’t a faulty sensor or wiring, as the PCM can only operate on the information it receives.
What is the security relearn procedure?
This is a simple procedure that syncs the new PCM with your vehicle’s anti-theft system. It typically involves turning the key to the ‘ON’ position for 10-12 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. This allows the components to recognize each other. Instructions are widely available online for your specific model.
Does this part fit other vehicles besides the Yukon?
Yes. This PCM is compatible with a wide range of 2001-2002 GM trucks, vans, and SUVs, including the Silverado, Sierra, Tahoe, Suburban, and Express/Savana vans. Please check the detailed fitment list on this page to confirm it matches your specific vehicle and options.
