Is Your GM Vehicle Acting Up? Get Back on the Road with Confidence.

There’s nothing more frustrating than a vehicle that won’t run right. If your 2004 Corvette, Silverado, or Express Van is suffering from a persistent check engine light, erratic idling, stalling, or a complete no-start condition, the problem often points to a failing Powertrain Control Module (PCM). This isn’t just a component; it’s the brain of your engine. When it fails, it can cause a cascade of confusing and debilitating issues, leaving you stranded and stressed. This pre-programmed Engine Control Module is the definitive solution to restore your vehicle’s performance and reliability.

Common Symptoms & Your Solution

A faulty PCM can manifest in numerous ways. You might be experiencing poor fuel economy, failed emissions tests, harsh shifting, or seeing diagnostic trouble codes (DTCs) like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault). Instead of guessing with used parts from a salvage yard that require expensive dealer programming, this module arrives ready for installation. We take your vehicle’s unique Vehicle Identification Number (VIN) and flash this unit with the latest, most stable software updates directly from GM. This ensures perfect compatibility and function for your specific vehicle. The 2004 Corvette PCM 89017739 is the smart, reliable fix to get you back in the driver’s seat.

  • ✔ VIN-Programmed for Your Vehicle: We flash the module with your car’s specific VIN, ensuring it communicates perfectly with your existing systems right out of the box.
  • ✔ Latest GM Software Updates: Benefit from the most recent factory software, which often corrects drivability issues and improves efficiency over the original programming.
  • ✔ Direct-Fit Replacement: Engineered to be a perfect replacement for OEM part numbers 89017739 and 12586243, guaranteeing a hassle-free installation.
  • ✔ Solves Complex Issues: The correct solution for eliminating false error codes, fixing erratic engine behavior, and resolving frustrating no-start problems related to the PCM.
  • ✔ Broad GM Compatibility: While a perfect fit for the 2004 Corvette, this versatile module is also the correct computer for dozens of other GM trucks, vans, and SUVs from that model year.
  • ✔ Peace of Mind Included: This unit is backed by our one-year replacement warranty.

Expert Insight: The P59 Controller Advantage

As a technician, I’ve seen countless hours and dollars wasted on incorrect diagnoses. The module you’re looking at, often called the ‘P59’ controller, was GM’s workhorse computer for the 2004 model year. Its power and versatility are why it was used in everything from a high-performance Corvette to a heavy-duty Sierra 3500. However, its complexity means that programming is NOT optional—it’s critical. A module from another vehicle simply will not work. Our process of programming the 2004 Corvette PCM 89017739 to your specific VIN before shipment eliminates the guesswork and the need for a trip to the dealership, saving you time and money.

Frequently Asked Questions

Is this unit truly ‘plug and play’?

For most vehicles, yes. After installation, you will need to perform a simple security relearn procedure, also known as a CASE relearn. This can typically be done in your driveway with just the ignition key and takes about 30 minutes. It syncs the new PCM with your vehicle’s anti-theft system. Instructions are readily available online for your specific model.

How do I provide you with my VIN?

After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as the programming is specific to your vehicle.

Will this fix my specific problem or check engine light?

If your vehicle’s issues have been correctly diagnosed as a faulty PCM, this part is the solution. It is designed to resolve DTCs like P0601 and other processor-related faults. However, it will not fix problems caused by other failed sensors or mechanical parts. A proper diagnosis is always recommended.

My original part is number 12586243. Will this work?

Yes. This module, 89017739, is a fully compatible and interchangeable service replacement for part number 12586243. It will function identically once programmed to your VIN.

Does this fit vehicles other than the 2004 Corvette?

Absolutely. This PCM is the correct computer for a wide range of 2004 GM vehicles, including the Silverado, Sierra, Suburban, Express, GTO, Trailblazer, and many more. Please check the detailed fitment list on this page to confirm compatibility with your vehicle.

Don’t let a bad computer keep your vehicle sidelined. Order your pre-programmed 2004 Corvette PCM 89017739 today and restore the performance and reliability you depend on.
