An Expert’s Note on Programming: Many people are tempted to grab a used computer from a salvage yard, hoping for a cheap fix. The problem is that a PCM is not a one-size-fits-all part. It’s coded specifically to the original vehicle’s VIN, options, and security system. Installing an unprogrammed module will, at best, not work and, at worst, create a cascade of new electronic issues. Our VIN-specific programming service eliminates that entire gamble. We ensure the module you receive is a perfect electronic handshake for your exact vehicle, saving you hours of diagnostic headaches and the cost of a tow to the dealer.
Take control of your repair and get your powerful GM truck or SUV running the way it was meant to. This fully programmed 89017734 PCM Engine Computer is the most reliable and efficient way to solve complex electronic issues and get back on the road with confidence.
Frequently Asked Questions
Do I need to do any programming myself?
No. The main programming is completed by us before shipment. After you purchase, you will provide us with your vehicle’s VIN, and we will flash the module with the correct GM software for your specific vehicle. In some cases, a simple security relearn procedure may be required after installation, which can be done without special tools.
How do I provide my VIN number?
After you complete your purchase, please send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is VIN-specific.
What is a security or CASE relearn?
The security relearn syncs the new PCM with your vehicle’s anti-theft system. It’s a simple procedure that typically involves turning the key to the ‘ON’ position for 10-15 minutes. A CASE (Crankshaft Angle Sensor Error) relearn may also be needed to sync the PCM with the crankshaft sensor, which requires a scan tool with that capability. Many local shops can perform this quickly if needed.
How can I be certain this part will fit my vehicle?
Please review the detailed fitment list on this page. The most important step is to match one of the compatible service numbers (like 89017734) listed. Providing your VIN for programming allows us to perform a final compatibility check before we ship.
What if I have an issue after installation?
Our goal is to get you back on the road successfully. If you encounter any issues, please contact our support team immediately. This unit is backed by our one-year replacement warranty, and our technicians are here to help you diagnose the problem.
