From the Technician’s Bench: We recently worked with a customer whose 2005 Saturn Ion Red Line had a baffling, intermittent no-start issue. They had already replaced the battery and starter to no avail. After diagnosing the system, we traced the fault to the original PCM’s ignition control circuit. Installing a freshly programmed 12589320 PCM Engine Computer not only solved the starting problem immediately but also smoothed out a slight idle hesitation the owner hadn’t even realized was related. Don’t chase ghosts in the machine—addressing the core electronic controller is often the fastest path to a reliable repair.
Frequently Asked Questions
What information do you need from me after I order?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot program and ship your 12589320 PCM Engine Computer without it. You can typically find your VIN on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your insurance and registration documents.
Is this a difficult part to install?
For most of the compatible models like the Cobalt and Pursuit, the PCM is located in the engine compartment and is very accessible. Installation typically involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then reversing the process with the new one. It’s a job many DIY mechanics can handle with basic hand tools.
Will I need to do anything else after installation?
In some cases, you may need to perform a security relearn procedure to sync the new PCM with your vehicle’s anti-theft system. This is a simple process that typically involves turning the key on and off in a specific sequence. We can provide instructions for this procedure upon request.
My original part number isn’t 12589320, but it’s on your list. Will this work?
Yes. Part numbers 12579132 and 12615197 are earlier or superseded versions. Our module, programmed to your VIN, is the correct and updated replacement for all the part numbers listed, ensuring full functionality.
What does “programmed with the newest updates” mean?
Vehicle manufacturers like GM often release software updates for their modules to improve performance, fix bugs, or enhance efficiency. When we program your PCM, we use the latest official software version available for your specific VIN, ensuring your vehicle runs better than ever.
