Is Your GM Truck or SUV Experiencing Frustrating Engine Problems?
A failing Powertrain Control Module (PCM) can bring your dependable truck to a dead stop, causing symptoms that range from annoying to debilitating. If you’re dealing with a persistent Check Engine Light, erratic transmission shifting, a sudden drop in fuel economy, or a dreaded no-start condition, the brain of your vehicle’s engine management system is likely the culprit. This isn’t just an inconvenience; it’s a critical failure that compromises your vehicle’s performance, reliability, and safety. Don’t let a faulty computer keep you off the road or force you into an expensive dealership visit.
Common Symptoms & Your Solution
A failing PCM can manifest in numerous ways. You might be experiencing one or more of the following issues:
- Check Engine Light (CEL) Illumination: Often with communication error codes like P0601, P0605, or P0606.
- Engine Stalling or Misfiring: The engine may run rough, stall unexpectedly, or refuse to start at all.
- Poor Performance & Fuel Economy: A noticeable loss of power and more frequent trips to the gas station.
- Erratic Automatic Transmission Shifting: Harsh shifts, delayed engagement, or getting stuck in one gear.
- Communication Issues: Your scan tool may be unable to communicate with the PCM.

Expert Insight: The Critical Role of Correct Programming
As a technician with over two decades of experience, I’ve seen countless vehicles towed in with a “Crank, No Start” condition after a DIY PCM replacement. The issue is almost always improper programming. A PCM is not a simple component; it’s the central command center. Without the correct VIN and software, it can’t communicate with the security system (VATS), the transmission controller, or the instrument cluster. Our pre-programming service for this Programmed 89017734 PCM isn’t just a convenience—it’s the most critical step to ensure your repair is successful the first time, saving you from immense frustration and diagnostic dead ends.
Frequently Asked Questions
What information do you need from me?
After you complete your purchase, we will need your 17-digit Vehicle Identification Number (VIN). This allows us to flash the module with the exact software and calibration file for your specific vehicle configuration.
Will I need to do anything after I install this PCM?
Yes. While the core engine and transmission programming is complete, you will need to perform a security relearn procedure (often called a VATS relearn). This process syncs the new PCM with your vehicle’s anti-theft system and can typically be done in your driveway in about 30 minutes without any special tools. Instructions are readily available online for your specific model.
Is this the correct part for my truck?
This Programmed 89017734 PCM fits a very wide range of GM trucks and SUVs from roughly 2003 to 2007. Please review the detailed fitment list on this page to confirm compatibility with your specific year, make, and model. Matching the service number is the best way to ensure you’re ordering the correct component.
Where is the PCM located on my vehicle?
On most of the compatible GM trucks and SUVs, the PCM is located in the engine bay on the driver’s side, under or next to the battery tray. It’s a silver metal box with multiple large electrical connectors.
What if my original part number isn’t listed?
If your original service number is not 89017734, 12582605, 12589463, 12602802, or another number listed in the compatibility chart, please contact us with your VIN before ordering. We can help verify the correct module for your application.
