Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is the central computer that controls your vehicle’s engine and transmission. It manages everything from fuel injection and ignition timing to emission systems and automatic transmission shift points to ensure peak performance and efficiency.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to do this. We cannot ship your part until we receive the VIN, as the programming is essential.
Is this module difficult to install?
For most of the listed vehicles, the PCM is in an accessible location (e.g., under the battery tray or in the engine compartment) and can be replaced with basic hand tools. After disconnecting the battery, you simply unplug the electrical connectors from the old module and install the new one. The physical swap is typically a simple process.
Will I need to do anything after installation?
In some cases, a security relearn procedure (also known as a Passlock or VATS relearn) may be required. This is a simple procedure that you can do yourself in about 30 minutes without any special tools. We can provide instructions for this. A Crankshaft Variation Relearn (CASE) may also be needed with a capable scan tool for optimal performance, though the vehicle will run without it.
What vehicles does this PCM fit?
This PCM is compatible with a wide range of 2001-2002 General Motors trucks, vans, and SUVs, including the Silverado, Sierra, Savana, Express, Tahoe, Yukon, Suburban, and Escalade, among others. Please see the full compatibility list in the description to confirm your specific model.
