Restore Peak Performance to Your 5.7L HEMI
Is your 2009 Jeep Grand Cherokee, Durango, or Dodge Ram 1500 running rough, stalling, or refusing to start? The Engine Control Module (ECM) is the electronic brain of your vehicle, managing everything from fuel injection and spark timing to emissions controls and transmission shifting. When it fails, it can cause a wide range of frustrating and difficult-to-diagnose problems. This direct-fit replacement ECM, part number 68059431AA, is the definitive solution to get your vehicle back on the road with reliability and confidence.
Unlike units that require expensive trips to the dealership for programming, this ECM arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN) and mileage. This means the installation process is simple and straightforward—a true ‘Plug and Play’ experience. We handle the complex programming so you can handle the installation, saving you time, money, and the headache of coordinating with a service center.
From the Diagnostic Bay
We had a 2009 Dodge Ram 1500 with the 5.7L HEMI come into the shop with a very peculiar issue. The owner complained of intermittent stalling, but only after the truck was fully warmed up and had been driven for over 30 minutes. It would never throw a specific code, just a generic P0606 (Internal Control Module Processor Error) that would clear itself. We checked fuel pressure, ignition components, and sensor data—everything looked perfect. On a hunch, we used a heat gun to carefully warm up the ECM while the truck was idling. Sure enough, after a few minutes, the engine sputtered and died. The thermal stress was causing a component on the main board to fail. We installed one of our pre-programmed ECMs, and the problem was solved instantly. These intermittent, heat-related issues are a classic sign of a failing computer.
Is Your 2009 Grand Cherokee ECM Failing?
A faulty engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following symptoms, a failing ECM is a likely culprit. Verifying these symptoms can help you make an accurate diagnosis and avoid replacing unnecessary parts.
Common Failure Symptoms
- ✔ Check Engine Light: An illuminated Check Engine Light is the most common sign, often with codes related to processor faults (P06xx series) or communication errors (U-codes).
- ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly, run rough, or misfire as the ECM fails to correctly control spark and fuel.
- ✔ No-Start Condition: Your vehicle may crank but refuse to start because the ECM isn’t activating the fuel pump or ignition coils.
- ✔ Poor Fuel Economy: Inaccurate sensor readings or faulty calculations can cause the engine to run rich, drastically reducing your MPG.
- ✔ Inconsistent Shifting: The ECM communicates directly with the transmission controller; a fault can lead to harsh or erratic shifting patterns.
- ✔ Communication Failure: A diagnostic scan tool may be unable to communicate with the ECM, indicating a total failure of the module.

Frequently Asked Questions
Is this ECM really “Plug and Play”?
Yes. We program the module with your vehicle’s specific VIN and mileage before shipping. This ensures it integrates seamlessly with your vehicle’s existing electronics, including the anti-theft system (SKIM/Sentry Key). No additional programming or dealer visit is required.
What information do you need from me to program it?
During the checkout process, we will require your vehicle’s 17-digit VIN (Vehicle Identification Number) and the current mileage. This is crucial for a successful programming service. Please double-check this information for accuracy.
Will this fix my check engine light?
This ECM will resolve any issues and diagnostic trouble codes directly caused by a faulty original computer. However, if the check engine light is on due to other failing components (like an oxygen sensor or catalytic converter), those issues will still need to be addressed separately.
Where is the ECM located on a 2009 Grand Cherokee?
On the 2009 Jeep Grand Cherokee, the ECM is typically located in the engine compartment, on the right-hand (passenger) side, towards the rear near the firewall. Always disconnect the battery before attempting to unplug or replace the module.
Is a core return required for this part?
Core return policies can vary. Please check the specific terms on the product page or contact our customer service. In many cases, returning your old, failed unit can provide you with a partial refund and helps us keep parts available for other customers.
