Restore Peak Performance to Your GM Vehicle
Is your 2001-2002 GM truck, van, or car suffering from baffling electrical issues? A faulty Powertrain Control Module (PCM), the central computer of your vehicle, is often the culprit behind problems like a persistent check engine light, poor engine performance, erratic shifting, or even a frustrating no-start condition. This replacement PCM, part number 12200411, is the definitive solution to restore your vehicle’s reliability and drivability. It serves as the brain, managing everything from fuel injection and ignition timing to transmission shift points and emissions controls. When it fails, the entire system is compromised.
The Smarter Solution: Pre-Programmed for Your Vehicle
Don’t settle for a generic, unprogrammed module that requires expensive trips to the dealership for flashing. We take the hassle and guesswork out of the repair. Before this unit ships, our technicians will program it with the latest official GM software calibration specifically for your vehicle. All we need is your Vehicle Identification Number (VIN) at checkout. This ensures that the module communicates perfectly with your vehicle’s existing systems right out of the box, saving you time and money.
We had a 2002 Chevy Silverado 2500 towed in that had every symptom of a bad fuel pump. It would crank all day but wouldn’t fire up. The owner had already replaced the pump, filter, and even the crank sensor. Our initial diagnostics showed good fuel pressure and spark. The mystery was the injectors – they weren’t firing. When we tried to connect our high-level scan tool, it kept giving a ‘No Communication with PCM’ error. After verifying all power and ground circuits to the module were intact, we knew the PCM itself had failed internally. A pre-programmed replacement like this one was the fix. Once installed and after a quick security relearn, the truck fired up on the first try and ran like new. It’s a classic failure that can send you chasing ghosts if you don’t consider the vehicle’s brain.
Is Your Vehicle Exhibiting These Symptoms?
A failing PCM can manifest in numerous ways. If you’re experiencing any of the following, a faulty engine computer could be the root cause:
- ✔ Persistent Check Engine Light (CEL) that won’t clear, or codes related to PCM communication errors (e.g., U-codes).
- ✔ Engine stumbling, misfiring, or running rough at idle.
- ✔ The vehicle cranks but refuses to start.
- ✔ A sudden, unexplained drop in fuel economy.
- ✔ Harsh, delayed, or incorrect automatic transmission shifting.
- ✔ Your mechanic’s diagnostic scanner cannot communicate with the vehicle.
- ✔ Intermittent stalling for no apparent reason.

Frequently Asked Questions
What is a VIN and why do you need it?
The VIN is your vehicle’s unique 17-digit identification number, like a fingerprint. We use it to load the exact, correct GM software and calibrations for your truck or van’s specific engine, transmission, and options, ensuring perfect compatibility.
Is this module difficult to install?
The physical installation is typically very simple, involving disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. The most important step after installation is performing the security relearn procedure, which does not require any special tools.
What is the security relearn procedure?
It’s a simple process to sync the new PCM with your vehicle’s anti-theft system. It usually involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating this cycle three times. We include instructions to guide you through it.
Is this a plug-and-play part?
It’s as close as it gets. Because it comes programmed to your VIN, it eliminates the need for dealership flashing. You just need to install it and perform the security relearn. In some rare cases, a Crankshaft Variation Relearn (CASE Relearn) may be needed with a scan tool, but the vehicle will run and drive without it.
Do I need to send my old computer back?
No. This purchase does not require you to return your old module. There is no core charge or need to send anything back to us.
