Get Your GM Truck or Van Running Right Again
Is your truck or van suffering from frustrating issues like a persistent check engine light, erratic shifting, a rough idle, or even a no-start condition? A failing Powertrain Control Module (PCM) is often the culprit, leaving you with an unreliable vehicle. This replacement PCM is the definitive, hassle-free solution to restore your vehicle’s performance and your peace of mind. It arrives at your door fully programmed to your specific Vehicle Identification Number (VIN), loaded with the latest factory software updates from GM. This means no expensive trips to the dealership for programmingโjust a straightforward installation to get you back on the road fast.

Expert Insight from a 20-Year Tech
I’ve seen hundreds of these early 2000s GM vehicles come through the shop. The original P01 series PCMs, like this programmed 12201281 PCM, were workhorses, but after two decades of heat cycles, vibration, and electrical stress, internal components like capacitors and processors can fail. This often manifests as bizarre, intermittent issues that are a nightmare to diagnose. A common failure is a cracked solder joint on the main processor, leading to a P0601 “Internal Control Module Memory Check Sum Error.” Simply swapping in a junkyard module won’t work due to the VIN security. This VIN-programmed unit is the only correct way to solve the problem permanently and reliably.
Frequently Asked Questions
Do I need to get this computer programmed?
No. We handle all the programming for you before we ship it. All we need is your vehicle’s VIN at checkout. This makes the installation process simple and straightforward.
What is the security relearn procedure?
After installation, you will need to perform a simple anti-theft relearn, also known as a CASE relearn. This procedure typically involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. This allows the new PCM to synchronize with your vehicle’s security system. No special tools are required.
Where is the PCM located on my vehicle?
On most trucks and SUVs like the Silverado, Sierra, and Tahoe, the PCM is located in the engine compartment on the driver’s side, often under or near the battery tray. On vans like the Express and Savana, it’s typically found in the rear of the driver’s side engine compartment.
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), this programmed 12201281 PCM will resolve the issue. However, if the light is on due to a faulty sensor or another component, that separate issue will still need to be addressed.
What information do you need from me?
We only need your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s registration, insurance card, or on a plate on the driver’s side of the dashboard visible through the windshield.
