Is Your 2009 5.7L HEMI Running Rough?
If you’re experiencing frustrating issues like a persistent check engine light, stalling, rough idling, or a complete no-start condition in your 2009 Jeep Commander, Dodge Durango, Ram 1500, or other compatible vehicle, the root cause is often a failing Engine Control Module (ECM). The ECM is the brain of your vehicle’s engine, responsible for managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it starts to fail, it can create a cascade of problems that are difficult to diagnose and can leave your vehicle unreliable or completely immobile.
From the Diagnostic Bay
I remember a 2009 Dodge Ram 1500 with the 5.7L HEMI that came into the shop with a list of bizarre, intermittent symptoms. The owner had already replaced the spark plugs, ignition coils, and even a fuel injector based on various codes that would pop up and then disappear. The truck would run fine for days, then suddenly start bucking and stalling at traffic lights. After hours of chasing electrical gremlins, we finally traced the issue back to the ECM. The internal circuitry was failing intermittently, sending corrupt data to the sensors and actuators. Swapping in a correctly programmed ECM like this one solved every single issue instantly. It’s a reminder that sometimes the most complex problems have a straightforward, central solution.
Common Symptoms of a Failing 2009 5.7L ECM
- âś” Check Engine Light: The check engine light is illuminated, often with communication-related trouble codes (U-codes) or multiple, seemingly unrelated sensor codes.
- âś” Engine Stalling or Misfiring: Your vehicle may stall unexpectedly while driving or at idle. You might also notice a rough idle or engine misfires that don’t seem to be caused by plugs or coils.
- âś” No-Start Condition: The engine cranks but refuses to start, indicating a potential lack of fuel or spark command from the ECM.
- âś” Poor Performance & Fuel Economy: A noticeable drop in acceleration, power, and a significant increase in fuel consumption are classic signs of an ECM struggling to manage the engine efficiently.
- âś” Harsh or Erratic Shifting: The ECM works in tandem with the transmission controller. A faulty module can lead to incorrect shift commands, resulting in hard shifts or gear hunting.
- âś” Cooling Fans Not Working: The ECM often controls the engine cooling fans. If they fail to turn on, it can lead to overheating.

Frequently Asked Questions
Is this engine computer truly Plug and Play?
Yes. We program the module with your vehicle’s specific VIN and mileage before shipping it to you. This ensures that it will integrate seamlessly with your vehicle’s existing systems, like the anti-theft (SKIM) system, without needing any additional programming from a dealer or mechanic.
What information do you need from me to program it?
During the checkout process, we will require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the exact mileage from your odometer. This information is critical for a successful programming process.
Where is the ECM located on my 2009 Jeep Commander?
On the 2009 Jeep Commander, the Electronic Control Module is typically located in the engine compartment on the right-hand (passenger) side. Always disconnect the battery’s negative terminal before attempting to remove or install any electronic modules.
Will this fix my check engine light?
If the check engine light and other symptoms are being caused by a faulty ECM, then this replacement part will resolve those issues. However, it is essential to have your vehicle properly diagnosed to ensure the ECM is the source of the problem and not a separate sensor or wiring issue.
Do I need to perform a ‘relearn’ procedure after installation?
In most cases, no extensive relearn procedure is necessary. Once installed, you may want to let the vehicle idle for a few minutes and then drive it for 10-15 miles to allow the module to synchronize with all vehicle sensors and systems for optimal performance.
