Is Your GM Vehicle Running Rough, Stalling, or Showing a Check Engine Light?
The Engine Control Module (ECM), often called the engine computer, is the central command center for your vehicle’s engine. It meticulously manages everything from fuel injection and ignition timing to emissions systems and transmission shifting. When the ECM begins to fail, it can cause a cascade of confusing and frustrating problems that can be difficult to diagnose. This replacement ECM, part number 12667002, is the definitive solution to restore your vehicle’s performance, reliability, and efficiency. We take the guesswork out of the repair by programming the module specifically to your vehicle’s unique Vehicle Identification Number (VIN) before it ever leaves our facility. This ensures a seamless installation process, getting you back on the road without the need for an expensive trip to the dealership for programming.
Common Symptoms of a Failing 2017 Caprice ECM
- ✔ Check Engine Light: The most common sign. Often accompanied by communication codes (U-series) or specific circuit fault codes.
- ✔ Engine Performance Issues: You may experience rough idling, stalling, hesitation during acceleration, or a noticeable loss of power.
- ✔ No-Start or Intermittent Start: The engine may crank but refuse to start, or it might start unreliably. This can happen when the ECM fails to control the fuel pump or ignition system.
- ✔ Reduced Fuel Economy: If the ECM isn’t managing the air-fuel mixture correctly, your vehicle’s gas mileage can drop significantly.
- ✔ Transmission Problems: The ECM works with the Transmission Control Module (TCM). A faulty ECM can lead to harsh shifting, getting stuck in gear, or other erratic transmission behavior.
- ✔ Apparent Sensor Failures: The ECM can send false signals, making it seem like various sensors have failed when the computer itself is the root cause.

Frequently Asked Questions
What is an ECM?
The ECM, or Engine Control Module, is a computer that acts as the ‘brain’ of your vehicle’s engine. It controls the fuel injectors, spark plugs, and idle speed, and monitors sensors to ensure the engine runs efficiently and cleanly.
Do I need to have this module programmed?
No. This module comes pre-programmed to your vehicle’s specific VIN. You must provide us with your VIN at the time of purchase so we can flash the unit with the correct software before shipping it to you.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your specific car. It contains information about the manufacturer, model, year, and options. We use it to load the exact factory software and calibrations your vehicle requires to run properly.
Will this fix my car’s problem for sure?
This part will correct any issues directly caused by a faulty ECM. However, it’s crucial to ensure your vehicle has been properly diagnosed. This module will not fix problems related to bad wiring, failed sensors, or mechanical engine issues.
Is a security relearn procedure required after installation?
In many cases, yes. Most GM vehicles require a simple security relearn procedure to sync the new ECM with your existing keys. This procedure typically takes 10-30 minutes and does not require any special tools. We can provide instructions for this process.
How do I find my original part number?
The part number is printed on a sticker on the case of your current ECM. You can compare it to the part numbers listed in this description (12667002, 12666070, 12667189) to confirm compatibility.
