An Expert’s Note on PCM Failure
As a technician with over two decades of experience, I’ve seen countless vehicles sidelined by a bad PCM. One of the most common and definitive failure codes is P0601 – “Internal Control Module Memory Check Sum Error.” This code means the PCM’s internal self-check has failed, and it can no longer be trusted to manage your engine correctly. It’s not a glitch you can clear; it’s a fatal hardware fault. Replacing the module is the only correct and lasting repair. Our process ensures your new PCM is not only a perfect match but also has the latest software to prevent common issues found in the original factory programming.
Getting your truck back to peak condition is simple. After purchase, provide us with your VIN. We’ll handle the complex programming, so you receive a part that’s ready for a straightforward installation. This is the most reliable way to restore your vehicle’s brain and get it running like new again. Don’t let a faulty computer keep your truck off the road—get the right part, programmed correctly, the first time.
Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM comes fully programmed to your vehicle’s VIN. In most cases, you will only need to perform a simple security relearn procedure, which involves turning the key on and off and can be done in your driveway without any special tools. We include instructions for this easy process.
What information do you need from me?
After you complete your purchase, we will need the 17-digit Vehicle Identification Number (VIN) from your Suburban. This allows us to load the exact correct software and calibrations for your specific engine, transmission, and options.
Where is the PCM located on my 2001-2002 Suburban?
On the 2001-2002 Suburban 1500, the PCM is typically located in the engine bay on the driver’s side (LH), mounted under the battery tray. Always disconnect the battery before attempting to remove or install the module.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the old PCM (like code P0601), then yes, this part is the correct solution. However, if the light is on due to another failed sensor or component on the vehicle, you will still need to diagnose and repair that separate issue.
Is this compatible with other GM trucks and SUVs?
Yes. While this listing is focused on the Suburban, this 2001-2002 Suburban 1500 Programmed PCM is also the correct computer for a wide range of GM vehicles from that era, including the Silverado, Sierra, Tahoe, Yukon, and Express/Savana vans.
