Restore Peak Performance to Your 3.7L Jeep
Is your 2009-2010 Jeep Commander or Grand Cherokee suffering from frustrating engine issues? Stalling, erratic idling, poor fuel economy, or a persistent check engine light can often be traced back to a failing Engine Control Module (ECM). As the central computer of your vehicle, the ECM is responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it falters, the entire vehicle’s performance and reliability are compromised. This direct-fit replacement ECM is the definitive solution to get your Jeep running like new again.
Diagnosing Your 2009-2010 Commander ECM
A faulty engine computer can manifest in numerous ways, often mimicking other sensor or component failures, which can make diagnosis tricky. If you’re experiencing a combination of the symptoms below, there’s a strong possibility your ECM is the culprit. Common indicators include a no-start condition where the engine cranks but won’t fire, sudden stalling while driving, noticeably reduced power, and inconsistent automatic transmission behavior. You may also have specific diagnostic trouble codes (DTCs) stored related to internal processor failure or communication errors with other modules.
From the Diagnostic Bay
We had a 2010 Grand Cherokee with the 3.7L V6 towed in that had two different shops stumped. The vehicle would start and run for a few minutes, then die suddenly and refuse to restart for an hour. All the sensor data looked good on the scan tool when it was running, but we noticed the 5-volt reference signal to the throttle body would drop out right before it stalled. After chasing wires and checking grounds with no success, we connected a scope to the ECM’s main processor. We found that as the module heated up, the processor would become unstable, causing the shutdown. Replacing the ECM with a correctly programmed unit resolved the issue permanently. It’s a classic example of how an internal computer fault can create a ghost in the machine that’s nearly impossible to find without direct component testing.

Frequently Asked Questions
What does the ECM do in my Jeep Commander?
The Engine Control Module, or ECM, is the main computer that controls all aspects of your 3.7L engine’s operation. It takes information from sensors all over the vehicle and uses it to manage the fuel injectors, spark plugs, throttle body, and emissions systems to ensure the engine runs efficiently and powerfully.
Is this module truly ‘Plug and Play’?
Yes. When you provide your vehicle’s VIN during checkout, we program the module with your vehicle’s specific software and security information. This means when you receive it, you can install it directly into your Jeep without needing any further programming from a dealership.
Where is the ECM located on my 2009-2010 Commander or Grand Cherokee?
On both the Jeep Commander and Grand Cherokee from this era, the ECM is typically located in the engine compartment on the right-hand (passenger) side, often near the firewall or inner fender.
Will this fix my check engine light?
If the check engine light is on due to an internal fault within your original ECM, then yes, this replacement part will solve the problem and allow the light to be cleared. However, if the light is on due to a separate failed sensor or component, that issue will still need to be addressed.
How do I know if I’m ordering the right part?
This ECM is guaranteed to fit the 2009-2010 Jeep Commander and 2009-2010 Jeep Grand Cherokee equipped with the 3.7L V6 engine. You can also match the part number on your existing module to the extensive list of compatible numbers provided in the description.
