An Expert’s Note on VIN Programming
As a technician, I’ve seen countless drivers try to save a few dollars with a junkyard computer, only to end up with a car that won’t start or shifts erratically. Why? Because the module wasn’t programmed for their specific car. Modern vehicles are complex systems where the engine, transmission, anti-lock brakes, and even the security system must communicate seamlessly. Our VIN programming service isn’t just a feature; it’s the essential step that makes this a true plug-and-play solution. We ensure your new Programmed 89017735 PCM is a perfect digital match for your vehicle, saving you the time, cost, and headaches of a dealership visit.

What exactly does a PCM do?
The Powertrain Control Module (PCM), often called the Engine Control Module (ECM), is the central computer for your vehicle’s powertrain. It controls critical functions like fuel injection, ignition timing, and automatic transmission shifting to ensure the engine runs efficiently and reliably.
What is the security relearn procedure?
This is a simple procedure that syncs the new PCM with your vehicle’s anti-theft system. It typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating the cycle two more times. We include easy-to-follow instructions for this process.
