Frequently Asked Questions
Do I need to do any extra programming after I receive this PCM?
No. We program the module to the VIN you provide before we ship it. It will arrive ready for installation. In some cases, a CASE relearn (Crankshaft Angle Sensor Error) or security relearn may be necessary, which can be performed with a capable scan tool or by following a simple vehicle-specific procedure.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or send it to us in a message referencing your order number. Your VIN is located on your driver-side dashboard (visible through the windshield) or on the driver-side door jamb sticker.
Is this the correct part for my 1997 Chevy S10?
This module, part number 16229684, fits a wide variety of 1997 GM models, including the S10, Blazer, Suburban, Tahoe, and many others with the 4.3L V6 engine. Please check the detailed fitment list on this page to confirm your exact make, model, and engine match.
What if my truck has an anti-theft system like Passlock/VATS?
GM’s anti-theft systems (VATS or Passlock) are tied to the vehicle’s components. After installing the new PCM, you may need to perform a security relearn procedure. This is a simple process that typically involves turning the key on and off in a specific sequence and can be done without any special tools. Instructions are widely available online for your specific model.
