Frequently Asked Questions
Is this module truly plug-and-play?
Because it comes programmed to your VIN, it is ready for installation. However, on most GM vehicles of this era, you will need to perform a security relearn procedure after installation. This procedure links the new PCM to your vehicle’s anti-theft system and can typically be done in your driveway in about 30 minutes without any special tools.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module until we receive this information.
Will this fix my check engine light?
This PCM will resolve any check engine light and diagnostic trouble codes that are directly caused by a faulty module itself (like internal processor failure code P0601). If your light is on due to other issues, such as a bad sensor or wiring problem, those issues will still need to be addressed separately.
Is this compatible with other part numbers?
Yes, this module is a direct replacement for several original equipment part numbers, including 12589462, 12602801, and 89017749. Please check the fitment list to confirm it matches your specific make, model, and engine.
What is the warranty on this module?
This unit is backed by our one-year replacement warranty, giving you confidence in your purchase.
