Expert Insight: The Dreaded P0601 Code
Many owners first discover their PCM is failing when they see the Check Engine Light and pull a P0601 code, which means “Internal Control Module Memory Check Sum Error.” In simple terms, the PCM has failed its own internal self-test. This is a hard fault, not a glitch. Clearing the code won’t fix it; it will always come back because the hardware itself is compromised. This is a clear signal that the module must be replaced. Installing our pre-programmed 2001-2002 Suburban 1500 PCM is the direct and permanent solution to this specific, common failure.
Whether you’re a seasoned mechanic or a DIYer trying to get your family vehicle back in service, this module provides a straightforward path to success.

Frequently Asked Questions
What information do you need from me?
After you place your order, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We use this to load the correct, updated GM software for your specific engine, transmission, and factory options.
Is this PCM difficult to install?
On most compatible trucks and SUVs, the PCM is located in the engine bay, often under the battery tray on the driver’s side. Installation typically requires basic hand tools to disconnect the battery, remove the old unit, and install the new one. It is a manageable job for a confident DIYer.
Will I need to do anything after installation?
In many cases, you may need to perform a security relearn procedure (often called Passlock or VATS) and a Crankshaft Variation Relearn (CASE relearn). These procedures can often be done without special tools, though a capable scan tool may be required for the CASE relearn. Instructions are widely available online for these models.
How do I know for sure that my PCM is the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis is key. A P0601 code is a direct confirmation of internal failure. If you don’t have that code, a professional mechanic should confirm that the power, ground, and data circuits going to the PCM are all functioning correctly before condemning the module.
What vehicles does this part fit?
This module is compatible with a very wide range of 2001-2002 GM trucks, vans, and SUVs, including the Silverado, Sierra, Tahoe, Yukon, Suburban, Express, and Savana, among others. Please refer to the detailed compatibility list on this page to confirm it fits your specific model and options.
