Is Your 2012 Captiva Sport Running Rough?
If your 2012 Chevrolet Captiva Sport is experiencing frustrating issues like stalling, erratic idling, a persistent check engine light, or a complete no-start condition, a failing Engine Control Module (ECM) is a likely culprit. The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it begins to fail, it can cause a cascade of problems that are often difficult to diagnose, leading to wasted time and money on incorrect repairs.
From the Diagnostic Bay
We once had a 2012 Captiva Sport come in with a persistent P0606 (ECM/PCM Processor Fault) code. The owner had already replaced the spark plugs, ignition coils, and even the mass airflow sensor with no success. The vehicle would intermittently lose power and sometimes refuse to start. After confirming all power and ground circuits to the module were solid, we identified the internal processor of the original ECM as the point of failure. A replacement, VIN-programmed module like this one had the vehicle running perfectly in under an hour. It’s a reminder that sometimes the ‘brain’ is the issue, not the ‘body’.
Symptoms of a Failing Engine Control Module
- ✔ Check Engine Light is illuminated with communication or processor-related codes (e.g., P0601, P0606).
- ✔ Engine performance issues such as stalling, misfiring, or hesitation.
- ✔ Noticeable decrease in fuel economy.
- ✔ Vehicle fails to start or starts intermittently.
- ✔ Automatic transmission shifting problems or harsh shifts.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Apparent failure of multiple unrelated sensors at the same time.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. This module comes fully programmed to your vehicle’s specific VIN. We handle all the software flashing before it ships, so it’s ready for installation right out of the box.
What is a VIN and why do you need it?
The VIN is your vehicle’s unique 17-digit identification number, like a fingerprint. We use it to load the exact software and calibrations your 2012 Captiva Sport requires for its specific engine, transmission, and options.
Where is the ECM located on a 2012 Captiva Sport?
On the 2012 Captiva Sport, the Engine Control Module is typically located in the engine compartment on the driver’s side (LH side), often near the air filter housing or firewall.
Is any additional setup required after installation?
In most cases, it is a simple plug-and-play installation. However, some GM vehicles may require a security relearn procedure (often called a Passlock or anti-theft relearn), which can typically be done without special tools. Instructions are widely available online or in service manuals.
How can I be sure this part will fit my vehicle?
This ECM fits the 2012 Captiva Sport and many other GM models. The best way to confirm is to match your original part number to one of the numbers listed (12616889, 12630908, 12637106, 12642665, 12650256, 12651993). Providing your VIN for programming also allows us to double-check compatibility.
