Restore Peak Performance to Your Vehicle

Expert Insight: The Heart of Your GM Truck or SUV
As a veteran technician, I’ve seen countless GM vehicles from this era sidelined by a failing PCM. The P59 controller, as it’s known in the industry, is a robust unit, but heat cycles and age can cause internal driver circuits to fail. This often leads to issues like a dead fuel injector or a non-firing ignition coil that mechanics misdiagnose as a bad part. The real problem is the PCM itself. Simply swapping in a junkyard unit won’t work due to the anti-theft system (Passlock/VATS). Our service bridges that gap, providing a properly programmed 2003 Chevy SSR PCM that not only fixes the hardware fault but also integrates seamlessly with your vehicle’s security system after a simple relearn procedure.
Frequently Asked Questions
Do I need to do anything after installing the PCM?
Yes. While the module is programmed for your engine and transmission, you will need to perform a security relearn procedure. This process syncs the new PCM with your vehicle’s anti-theft system and keys. It is a simple procedure that typically takes 30 minutes and does not require any special tools.
How do I provide my VIN number?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. Please double-check the VIN for accuracy before sending.
Is this the correct part for my vehicle?
This PCM is compatible with a wide range of GM trucks and SUVs. Please review the detailed fitment list on this page and verify that your vehicle’s year, make, model, and engine are listed. Matching one of the service numbers (e.g., 28042802, 12602802) is the best way to confirm compatibility.
What if my original part number is different from 28042802?
No problem. This PCM is a direct replacement for multiple service numbers, including 89017750, 12582605, 12589463, 12602802, and 89017734. As long as your original module has one of these numbers, this unit will work perfectly.
What does “VIN-programmed” actually mean?
It means we use professional equipment to load your vehicle’s specific factory software and calibration files onto the module before we ship it. This makes the unit specific to your truck or SUV, ensuring all systems, options, and emissions components function exactly as the manufacturer intended for your 2003 Chevy SSR PCM.
