Restore Peak Performance to Your GM Truck or Van
Is your work van or truck suddenly running rough, refusing to start, or throwing a cascade of confusing check engine lights? A failing Powertrain Control Module (PCM) can bring your vehicleโand your daily routineโto a grinding halt. This isn’t just an inconvenience; it’s downtime that costs you time and money. Get your vehicle back in service with this direct-replacement, professionally programmed PCM, engineered to restore the reliable performance you depend on.
Common Symptoms of a Failing PCM & Your Direct Solution
A faulty engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a bad PCM is a likely culprit:
- No-Start Condition: The engine cranks but won’t start, despite having fuel and spark.
- Check Engine Light with Communication Codes: Diagnostic Trouble Codes (DTCs) like P0601, P0602, P0605, or P0606 specifically point to an internal module failure.
- Erratic Engine Behavior: Unexplained stalling, rough idling, poor acceleration, or a sudden drop in fuel economy.
- Transmission Shifting Issues: Harsh or delayed shifting that isn’t related to the transmission itself.
- Apparent Sensor Failures: Multiple, unrelated sensor codes appearing simultaneously can indicate the PCM is no longer processing signals correctly.
This Programmed 12602801 PCM is the definitive solution. We take the guesswork out of the repair by flashing the unit with the latest official GM software updates, tailored specifically to your vehicle’s Vehicle Identification Number (VIN). This ensures seamless integration and correct operation of all engine and transmission parameters from the moment of installation.

An Expert’s Diagnostic Tip
We recently worked with a shop owner who had a 2006 Silverado 2500 with the 8.1L engine. The truck had a persistent random misfire code that wouldn’t go away. He had replaced the plugs, wires, coils, and even the fuel injectors, wasting hundreds of dollars and countless hours. The real issue was a failing driver circuit inside the original PCM. Once he installed our Programmed 12602801 PCM, the misfire was gone instantly. Always consider the PCM when multiple, unrelated codes appear after you’ve checked the basics.
Don’t let a faulty computer keep your reliable GM vehicle off the road. This is the most efficient and dependable way to solve complex electronic issues and restore the performance you need. By providing us with your VIN at checkout, you ensure that the Programmed 12602801 PCM you receive is perfectly matched to your vehicle’s specific configuration.
Frequently Asked Questions
How does the VIN programming process work?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the official GM database and load the exact software and calibrations your vehicle had when it left the factory, including any subsequent updates. This ensures a perfect match.
Will I need to do anything after I install it?
In most cases, you will need to perform a simple security relearn procedure (often called a Passlock or Passkey 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 with just your ignition key. Instructions are readily available online for your specific model.
What part numbers does this module replace?
This PCM is a direct replacement for service numbers 12589462, 12602801, and 89017749. Please check the extensive fitment list to confirm compatibility with your specific year, make, and model.
Where can I find my vehicle’s VIN?
Your VIN can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
What if I have an issue after installation?
Your purchase is protected. This unit is backed by our one-year replacement warranty. If you encounter any issues with the module itself, please contact us, and our support team will be ready to assist you.
