Is your truck or SUV suffering from frustrating issues like a persistent check engine light, erratic shifting, stalling, or a complete no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the central computer of your vehicle. Don’t let a faulty module keep your reliable GM vehicle off the road. This direct-fit Programmed 12602802 PCM is the definitive, hassle-free solution to get you back in the driver’s seat with confidence.
Common Symptoms & Your Solution
A failing PCM can cause a wide range of confusing problems. If you’re experiencing any of the following, this module is the solution you need:
- Check Engine Light (CEL) Illumination: Often with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0602, P0606, or U0100.
- Engine Performance Issues: Stalling, hesitation, rough idling, misfires, or reduced fuel economy.
- Transmission Problems: Harsh or delayed shifting, or getting stuck in one gear (limp mode).
- No-Start Condition: The engine cranks but refuses to start, often due to a lack of fuel injector or ignition coil command from the PCM.
- Network Communication Failures: Your scan tool cannot communicate with the engine computer.
Replacing your old module with our professionally Programmed 12602802 PCM resolves these issues by restoring the critical link between your vehicle’s sensors and its mechanical systems, ensuring everything operates exactly as the factory intended.

Expert Insight: The Critical Role of VIN Programming
As a technician with over two decades of experience, I’ve seen countless vehicle issues caused by improperly matched control modules. Simply grabbing a used PCM from a junkyard might seem like a cheap fix, but it’s a recipe for disaster. A module from a different vehicle will have the wrong software for your engine size, transmission type, and even tire size, leading to immediate running problems and check engine lights. Our VIN programming service isn’t just a convenience—it’s the most crucial step in ensuring the repair is done right the first time, saving you from future headaches and diagnostic nightmares.
Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM), also known as the Engine Control Module (ECM), is your vehicle’s main computer. It controls all aspects of engine and transmission function, from fuel injection and spark timing to transmission shift points, to ensure optimal performance, fuel efficiency, and emissions.
How do I provide my VIN for programming?
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 each module is custom-programmed for a specific vehicle.
Is any additional programming needed after installation?
In most cases, no. Our programming covers the engine and transmission operating systems. However, on many of these GM vehicles, a security relearn procedure (often called CASE relearn or Passlock relearn) is required. This is a simple procedure that can be done without special tools and typically involves a sequence of key turns. Instructions are readily available online for your specific model.
How do I know if this part will fit my vehicle?
This Programmed 12602802 PCM fits a wide range of GM models. Please check the extensive compatibility list on this page. The best way to ensure a match is to verify that your original module has one of the compatible service numbers listed (e.g., 89017750, 12582605, 12589463, 12602802).
Is this a new or used part?
This is a quality, inspected, and tested used OEM component. Each unit is verified to be fully functional before it is programmed to your VIN, providing OEM-level reliability without the OEM price tag.
