Is your 2001-2002 GMC Sierra 1500 running rough, shifting erratically, or showing a persistent check engine light? A failing Powertrain Control Module (PCM) is often the culprit, bringing your dependable truck to a frustrating standstill. This isn’t just a replacement part; it’s a complete, ready-to-install solution. We provide a fully programmed 2001-2002 Sierra 1500 PCM, flashed with the latest GM software to your truck’s specific VIN, restoring the performance and reliability you depend on.

- Rough or inconsistent idling
- Poor fuel economy
- Harsh or failed transmission shifting
- Engine stalling or no-start conditions
- Communication errors with diagnostic scan tools
This module is the definitive fix for these electronic issues. By replacing your old unit with our professionally prepared PCM, you’re not just clearing codesโyou’re addressing the root cause and giving your engine the precise instructions it needs to run smoothly.

Expert Insight: Why VIN-Specific Programming is Non-Negotiable
Many sellers offer ‘blank’ or used PCMs, leaving the most critical step up to you. A PCM is not a one-size-fits-all part. Your Sierra has a unique combination of engine, transmission, axle ratio, and emissions systems. Our VIN-based programming ensures the module we send is precisely configured for your truck’s DNA. This critical step prevents compatibility conflicts, ensures all onboard systems communicate correctly, and is the only way to guarantee a true plug-and-play repair. Don’t settle for a generic partโget the specific solution your truck requires.
This is the most reliable and straightforward way to get your truck back in top form. We handle the complex programming so you can focus on the simple installation. When you need a programmed 2001-2002 Sierra 1500 PCM that works right out of the box, this is your answer.
Frequently Asked Questions
Do I need to do any programming myself?
No. We program the PCM to the VIN you provide before shipping. The unit will be ready to install. In some cases, you may need to perform a simple security relearn procedure, which takes about 30 minutes and does not require any special tools.
Where do I provide my vehicle’s VIN?
Please enter your 17-digit VIN in the notes section during checkout. If you forget, we will contact you via email to request it before we can program and ship your order.
Is this the correct part for my vehicle?
This PCM is compatible with the vehicles listed in the fitment guide and replaces part numbers 12200411, 12201281, 12576160, and 52369718. Please verify the part number on your original module or contact us with your VIN if you are unsure.
What is a security relearn procedure?
It’s a simple process that syncs the new PCM with your vehicle’s anti-theft system. It typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating this cycle three times. We include instructions for this straightforward procedure.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of your original PCM (e.g., code P0601), this module will resolve the issue. However, if the light is on for other reasons, such as a faulty sensor, those issues will need to be addressed separately.
How long does the programming process take?
Programming is typically completed within 1-2 business days after we receive your VIN. Your order will then be shipped promptly.
