Frequently Asked Questions
Do I need to do anything after I install this PCM?
Yes. You will need to perform a security relearn procedure to sync the new PCM with your vehicle’s anti-theft system. This is a simple process that takes about 30 minutes and can be done without any special tools. We provide clear instructions to guide you.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your vehicle’s 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.
Is this a brand new part?
This is a high-quality, tested, and verified replacement module that meets or exceeds original equipment specifications. It is programmed with the latest GM software to ensure optimal performance and reliability.
How do I know for sure that my PCM is the problem?
While the symptoms listed above are strong indicators, it’s always best to have a proper diagnosis. Common signs of a bad PCM include internal processor fault codes (P0601-P0606) or a complete lack of communication with a scan tool. If other components like sensors and wiring have been checked and are in good working order, the PCM is the likely culprit.

This module, service number 89017733, is compatible with a wide variety of 2003 GM vehicles, including the Blazer, Jimmy, Astro/Safari vans, Express/Savana vans, and several V8-equipped trucks and SUVs like the Silverado, Sierra, and Yukon.
