Is Your GM Truck or SUV Experiencing Frustrating Engine Problems?
If you’re dealing with a persistent check engine light, erratic engine behavior, stalling, or poor fuel economy, a failing Powertrain Control Module (PCM) is often the culprit. As the central computer for your vehicle, a faulty PCM can cause a cascade of issues that leave you stranded and frustrated. This isn’t just an inconvenience; it’s a critical failure that compromises your vehicle’s performance and reliability. Get your truck or SUV back to its dependable best with this direct-replacement, VIN-programmed engine computer.
Common Symptoms & Your Solution
A failing PCM can manifest in many ways. You might be experiencing one or more of the following:
- Check Engine Light (CEL) with communication-related trouble codes (e.g., P0601, P0606).
- No-Start or Hard-Start Condition: The engine cranks but refuses to start, or starts only after extended cranking.
- Erratic Shifting or Transmission Issues: The PCM controls transmission behavior, and a fault can lead to harsh shifts or getting stuck in gear.
- Reduced Power and Poor Fuel Economy: Incorrect fuel and timing calculations can severely impact performance and efficiency.
- Stalling for No Apparent Reason: The engine may cut out while driving or idling.
This fully Programmed 89017750 PCM is the definitive solution to these problems. It arrives at your door ready to install, pre-flashed with the latest official GM software tailored specifically to your vehicle’s Vehicle Identification Number (VIN).

Expert Insight: The Critical Role of VIN Programming
On these early 2000s GM vehicles, the PCM is more than just an engine controller; it’s the heart of the entire vehicle network. It communicates with the Body Control Module (BCM), transmission, and anti-theft system (VATS/Passlock). Simply swapping a used, unprogrammed module will result in a no-start condition every time. Our VIN-specific programming ensures all these systems communicate correctly from the moment you turn the key, just as the factory intended. This is the key to a successful and lasting repair.
Don’t let a faulty computer keep your reliable truck or SUV off the road. By providing us with your VIN upon purchase, you ensure you receive a perfectly matched Programmed 89017750 PCM that will restore the performance and dependability you count on. Take control of your repair and get back behind the wheel with confidence.
Frequently Asked Questions
Do I need to do any programming myself?
No. This module comes fully programmed to the VIN you provide. The only step you may need to perform after installation is a simple security relearn procedure, which can be done without any special tools and typically takes about 30 minutes. We can provide instructions for this process.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my specific problem?
This Programmed 89017750 PCM is a direct solution for a failed module. While it resolves the vast majority of the symptoms listed, it’s essential to ensure your vehicle has been properly diagnosed. Other issues, such as faulty wiring or failed sensors, can sometimes mimic PCM failure.
Is this compatible with other part numbers?
Yes, this unit is a direct replacement for a wide range of GM service numbers, including 89017750, 12582605, 12589463, 12602802, 89017734, and 28042802. If your original module has one of these numbers, this part is a correct fit.
What if my vehicle has modifications?
This PCM is programmed with the stock GM calibration for your specific VIN. It is not designed to account for significant aftermarket modifications like forced induction, non-stock camshafts, or major engine changes.
