An Expert’s Insight: As a technician with over two decades of experience, I’ve seen countless vehicle owners get stuck after installing a generic, non-programmed computer. They’d replace the part, but the vehicle still wouldn’t start or would run poorly because of security system conflicts (like GM’s Passlock/VATS). Our process of programming the module to your VIN before it ships is the single most important step. It pre-authorizes the module to communicate with your vehicle’s other systems, turning a potentially complex job into a manageable one. This isn’t just a part; it’s a complete, ready-to-install solution.
Frequently Asked Questions
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the module correctly for your specific vehicle configuration.
Is any additional programming needed after installation?
This Programmed 89017750 PCM arrives ready for installation. However, you will need to perform a security relearn procedure (often called a CASE relearn or anti-theft relearn). This procedure syncs the new module with your vehicle’s anti-theft system and can typically be done without any special tools. We can provide instructions for this simple process.
Do I need to send my old PCM (core) back?
No. There is no core charge or core return required for this part, saving you time and return shipping costs.
How do I know if my PCM is the problem?
While the symptoms listed above are common indicators of PCM failure, a proper diagnosis is always the best first step. This involves checking for diagnostic trouble codes (DTCs) with a scanner, verifying good power and ground connections at the module, and ruling out any faulty sensors or wiring issues.
Will this fit my truck if my original part number is different?
Yes, this module is a direct replacement for multiple GM service numbers, including 89017750, 12582605, 12589463, 12602802, and more. Please check the detailed fitment list on this page to confirm compatibility with your specific make, model, and year.
