Frequently Asked Questions
Do I need to do any programming after I receive this PCM?
No. This PCM comes fully programmed to the VIN you provide during checkout. It is ready for installation right out of the box. You will, however, need to perform a security relearn procedure, which is a simple process that can be done without any special tools.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is required for the programming service.
Will this fit my 2001 Silverado 3500?
Yes, this PCM is the correct fit for any 2001 model year Chevrolet Silverado or GMC Sierra 2500 and 3500 pickup with the Duramax diesel engine. Programming is tailored to your specific vehicle using your VIN.
What if my original part number is slightly different?
That’s very common. GM often uses several interchangeable part numbers for the same component. As long as your vehicle is a 2001 GM HD truck with a diesel engine, this is the correct computer. We program it based on your VIN, which guarantees compatibility.
Is this the only computer my truck has?
The PCM (Powertrain Control Module), also known as the ECM (Engine Control Module), is the main computer that controls all engine and transmission functions. Your truck also has other modules, like a Body Control Module (BCM) or a Transfer Case Control Module (TCCM), but this 2001 Sierra 2500 Duramax PCM is the primary controller for the powertrain.
What is the warranty on this part?
This unit is backed by our one-year replacement warranty.
