Is Your GM Truck or SUV Acting Up? Get it Running Right.
There’s nothing more frustrating than a vehicle you can’t rely on. If your Trailblazer, Envoy, or Colorado is suffering from erratic behavior like stalling, rough idling, or a persistent Check Engine Light, the problem often points directly to a failing Powertrain Control Module (PCM). This isn’t just an inconvenience; it’s the central computer of your vehicle, and when it falters, it affects everything from fuel economy to engine performance. Stop chasing symptoms and address the root cause with a reliable, correctly programmed replacement.
Common Symptoms & Your Solution
A failing PCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, this module is your definitive solution:
- Persistent Check Engine Light (CEL) with codes like P0601, P0602, P0606, or U-series communication codes.
- Engine stalling or shutting off unexpectedly while driving.
- Difficulty starting the engine or a complete no-start condition.
- Noticeable decrease in fuel efficiency.
- Poor or harsh shifting from the automatic transmission.

Frequently Asked Questions
What exactly is a PCM?
The Powertrain Control Module (PCM), also known as the Engine Control Module (ECM), is your vehicle’s main computer. It controls all aspects of the engine and transmission to ensure optimal performance, fuel economy, and emissions.
How do I provide my VIN number?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is specific to your vehicle.
Will I need to do anything after installation?
In most cases, this is a direct plug-and-drive installation. However, some vehicles may require a simple crankshaft position sensor relearn procedure, which can be done with a capable scan tool. This is a standard step for this type of repair.
Is this a new or used part?
This is a quality, inspected, and tested original equipment part that has been professionally programmed to function like new. We ensure every unit passes our rigorous quality control checks before it is programmed and shipped.
What if my original part number is not 12569773?
This module is a direct replacement for a wide range of GM part numbers, as listed in the description. As long as your vehicle’s year, make, model, and engine match the compatibility list, this unit, once programmed to your VIN, will function correctly.
How can I find my 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.
