An Expert’s Note: I’ve seen countless DIY mechanics and even professional shops chase their tails for weeks trying to solve intermittent stalling or a random no-start on these early 2000s GM trucks. They replace fuel pumps, crank sensors, and ignition coils, only for the problem to return. More often than not, the root cause is a failing PCM with internal circuit board issues. Getting a pre-programmed module like this one eliminates the guesswork and the costly, time-consuming trip to a dealership for programming. It’s the most efficient way to get a reliable fix and get your truck back to being the dependable workhorse it was built to be.

Frequently Asked Questions
Do I need to program this PCM?
No. We handle all the programming for you before we ship the part. All you need to do is provide us with your vehicle’s VIN during or after checkout. It will arrive ready for installation.
What information do you need from me?
We only need your 17-digit Vehicle Identification Number (VIN). This allows us to flash the module with the exact software and calibrations for your truck’s specific engine, transmission, and options.
Will this fix my check engine light?
If your check engine light is on due to a diagnostic trouble code related to an internal PCM failure (like P0601 – Internal Control Module Memory Check Sum Error), then this part will solve the problem. It will not fix issues related to other faulty sensors on the vehicle.
Is a security relearn required after installation?
Yes, on virtually all GM vehicles of this era, you will need to perform a security relearn procedure after installing the new PCM. This syncs the module with your vehicle’s anti-theft system and keys. It’s a simple process that typically takes 10-30 minutes and does not require any special tools.
Where can I find my VIN?
Your VIN can be found in several places: on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
What if I have an aftermarket performance chip?
This PCM is programmed with the latest stock GM calibration. It is not designed to work with aftermarket performance chips or software. Installing this module will return your vehicle to its factory operational parameters.
