- ✔ Unexplained Check Engine Light (CEL) illumination, often with communication-related trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ The vehicle cranks but refuses to start.
- ✔ Misfire codes that persist even after replacing spark plugs, coils, and wires.
- ✔ Failure to pass an emissions test.

Frequently Asked Questions
Do I need to get this PCM programmed?
No. This PCM comes fully pre-programmed to your vehicle’s specific VIN. We handle all the flashing with the latest GM software before it ships, saving you a trip to the dealership.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information.
What is a CASE relearn and will I need to do it?
A CASE (Crankshaft Angle Sensor Error) relearn synchronizes the PCM with the crankshaft position sensor. Many vehicles will require this procedure after PCM replacement to prevent misfire codes. It can be performed with most professional-grade scan tools.
Where is the PCM located on my vehicle?
The location varies. On most trucks and SUVs like the Silverado, Sierra, and Tahoe, it’s under the hood on the driver’s side, often under or near the battery. On vans like the Express and Savana, it’s typically in the LH rear of the engine compartment. Always consult a repair manual for your specific model.
Is this compatible with my 2002 Chevrolet Silverado 1500?
Yes, this module is compatible with the 01-02 Silverado 1500, as well as a wide range of other GM vehicles listed in the fitment guide. Our VIN programming ensures it will work correctly for your specific application.
