Frequently Asked Questions
What exactly does the PCM do?
The Powertrain Control Module (PCM), often called the engine computer, is the central processor for your vehicle. It controls all aspects of engine and transmission function, from fuel injection and spark timing to transmission shift points and emissions systems, to ensure optimal performance and efficiency.
Is this module difficult to install?
The physical installation is straightforward for someone with basic mechanical skills, as it’s a direct-fit part. However, after installation, you will likely need to perform a security relearn procedure (often called a CASE relearn or Passlock relearn) to sync the new PCM with your vehicle’s anti-theft system. This procedure can typically be done without special tools and instructions are widely available.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot program and ship your module until we receive this information, so please provide it promptly to avoid delays.
Will this fix my check engine light?
If the check engine light is on due to an internal failure of your original PCM (like codes P0601 or P0606), this replacement unit is designed to solve that problem. If the light is on for another reason, such as a faulty sensor, that issue will need to be addressed separately.
What if my truck has modifications?
This PCM is programmed with standard factory calibrations from GM. It is intended for vehicles with stock or near-stock configurations. It is not designed to account for significant aftermarket modifications like forced induction, aggressive camshafts, or non-stock injector sizes.
Does this fit other vehicles besides the Silverado 2500?
Yes. This 2001-2002 Silverado 2500 PCM 12200411 is compatible with a very wide range of GM trucks, vans, and SUVs from that era. Please check the detailed fitment list on this page to confirm it is the correct part for your specific make and model.
