Frequently Asked Questions
Do I need to do anything after installation?
After installing the module, you may need to perform a security relearn procedure (also known as a CASE relearn or Passlock relearn). This is a simple process that typically involves turning the key on and off in a specific sequence and does not require special tools. Instructions are readily available online for your specific model.
How do I provide my VIN number?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. You can find your VIN on your vehicle’s dashboard (visible through the windshield) or on your registration and insurance documents.
Is this compatible with my Chevy S10 or GMC Jimmy?
Yes, absolutely. This PCM fits a very wide range of GM vehicles from the late 90s and early 2000s that use part number 16263494 and its equivalents. This includes many Chevy, GMC, Oldsmobile, and Cadillac trucks, vans, and SUVs. Please check the detailed fitment list in our description to confirm for your specific model.
What if my original part number isn’t on your list?
Please contact us with your vehicle’s VIN and the part number from your original module. We can verify compatibility and ensure you receive the correct, fully programmed PCM for your application. Correctly matching the hardware is crucial.
Why is a programmed module better than a used one from a junkyard?
A used module from another vehicle will not work correctly because it’s programmed for that vehicle’s specific VIN and options. This can cause a no-start condition, warning lights, and improper function. Our programmed 1998-2000 Isuzu Hombre PCM is specifically flashed for YOUR vehicle, ensuring it works correctly right out of the box.
