Unlike a generic, non-programmed unit, this 2001 Silverado 3500 diesel PCM is meticulously flashed to your specific VIN. This process ensures all the unique parameters for your truck’s configuration are loaded correctly, which is the only way to restore the factory-level performance and durability these legendary work trucks are known for.
Frequently Asked Questions
Do I need to do anything after installing this PCM?
In most cases, you will need to perform a security relearn procedure, also known as a CASE relearn, which can typically be done without special tools. This syncs the new PCM with your truck’s anti-theft system and crankshaft position sensor. Instructions are widely available online for this simple process.
Where is the PCM located on my 2001 truck?
The Electronic Control Module, or PCM, is located on the driver’s side of the engine bay, on the front of the fender well, just under the battery tray.
How do I provide you with my VIN?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the part to function in your truck.
Will this fit my gas engine truck?
