Is Your GM Vehicle Running Rough, Stalling, or Showing a Check Engine Light?
A faulty Powertrain Control Module (PCM) can be the source of countless frustrating and hard-to-diagnose issues. If you’re experiencing erratic engine behavior, poor fuel economy, harsh shifting, or a no-start condition, your vehicle’s brain may be failing. This isn’t just an inconvenience; it affects your vehicle’s reliability and your confidence on the road. Don’t keep guessing with other parts. Get the definitive solution and restore your vehicle’s performance and dependability.
Common Symptoms & Your Solution
This module is the core of your vehicle’s engine and transmission management. When it fails, it can trigger a wide range of problems and diagnostic trouble codes (DTCs). This Programmed 12200411 PCM is the direct solution for issues such as:
- Check Engine Light with codes like P0601, P0602, P0606 (Internal Controller Failure)
- Engine stalling or cutting out intermittently
- Rough or unstable idle
- Harsh or erratic automatic transmission shifting
- Failure to communicate with a scan tool
- Reduced engine power or poor acceleration
- Vehicle won’t start, despite having power

An Expert’s Note on PCM Programming
As a technician, I’ve seen countless vehicle owners waste time and money on un-programmed or incorrectly programmed modules. A PCM isn’t a one-size-fits-all part. Every vehicle has a unique software calibration based on its engine, transmission, and options. Our VIN-specific programming service ensures that the computer you receive is an exact match for your vehicle’s requirements. This critical step prevents a host of potential issues, from incorrect transmission shift points on a Silverado to fuel trim problems on a Corvette. We handle this essential process for you, so you can be confident the job is done right the first time.
Frequently Asked Questions
How do I provide my VIN?
You can add your 17-digit Vehicle Identification Number (VIN) in the notes section during the checkout process. If you forget, we will contact you via email after your purchase to retrieve it. We cannot ship your Programmed 12200411 PCM until we have your VIN.
Is any additional programming needed after installation?
Our programming covers the engine and transmission operating system. However, on virtually all of these GM vehicles, you will need to perform a security relearn procedure (often called VATS or Passlock) so the vehicle will start. This procedure takes 15-30 minutes and can be done without any special tools. Instructions are readily available online for your specific model. Some vehicles may also require a Crankshaft Position Sensor (CASE) relearn with a capable scan tool for optimal performance, though the vehicle will still run without it.
Where is the PCM located on my vehicle?
The location varies by model. On most trucks and SUVs like the Silverado, Sierra, and Tahoe, it’s located in the engine bay, on the driver’s side, often under or near the battery tray. On vans like the Express and Savana, it’s typically in the rear of the engine compartment. For cars like the Camaro and Corvette, it’s usually found behind a strut tower or near the firewall on the passenger side.
Will this work if my vehicle has modifications?
This PCM is programmed with standard, factory GM calibrations. It is intended for vehicles with stock or very minor modifications (like a cat-back exhaust). It is not designed for vehicles with significant changes like different camshafts, forced induction, or non-stock injectors.
How can I be sure my original PCM is the problem?
While the symptoms listed are very common for PCM failure, it’s crucial to perform proper diagnostics. We recommend checking all power and ground circuits to the module and ruling out other potential causes, such as faulty sensors or wiring issues, before ordering a replacement. A diagnostic code like P0601 (Internal Control Module Memory Check Sum Error) is a strong indicator of PCM failure.
