Restore Peak Performance to Your Jeep
Is your 2009-2010 Jeep Commander or Grand Cherokee running rough, stalling, or refusing to start? Are you plagued by a persistent Check Engine Light that points to a faulty engine computer? You’ve come to the right place. This Engine Control Module (ECM), part number 68028154, is the definitive solution to restore your vehicle’s engine management system to its original, factory-specified operation. The ECM is the brain of your vehicle, controlling everything from fuel injection and ignition timing to emissions systems and transmission shifting. When it fails, the symptoms can be frustrating and widespread, but the fix doesn’t have to be complicated or expensive.
Unlike a trip to the dealership, which often involves long waits and high costs for programming, our ECMs arrive at your doorstep fully programmed to your vehicle’s specific Vehicle Identification Number (VIN) and current mileage. This means the installation is a true plug-and-play process. There is no need for additional flashing, key relearning, or trips to a mechanic with specialized tools. Simply install the module, and you’re ready to get back on the road with confidence.
Expert Pro Tip
Before replacing your ECM, always perform a thorough check of the vehicle’s battery, alternator, and primary ground connections. A weak battery or a corroded ground wire can cause erratic voltage, leading to symptoms that mimic a failing engine computer. A simple check with a multimeter can save you from a costly misdiagnosis. Ensure all connections to the ECM are clean and tight.
Common Symptoms of a Failing 2009-2010 Commander ECM
A failing engine computer can manifest in numerous ways. If you’re experiencing any of the following issues, a faulty ECM is a likely culprit. This module is designed to correct these exact problems and restore the precise control your engine needs.
- ✔ Check Engine Light: The Check Engine Light is illuminated, and you may have diagnostic trouble codes (DTCs) related to the PCM, sensor circuits, or communication errors (e.g., P0600, P0601, P0606).
- ✔ No-Start or Hard-Start Condition: The engine cranks but refuses to start, or takes an unusually long time to fire up, either hot or cold.
- ✔ Engine Stalling: The engine stalls unexpectedly while driving or when coming to a stop at idle.
- ✔ Poor Engine Performance: You may notice a significant loss of power, hesitation during acceleration, or jerky movements.
- ✔ Reduced Fuel Economy: A faulty ECM can’t properly manage the air-fuel mixture, leading to a noticeable drop in your vehicle’s gas mileage.
- ✔ Rough or Unstable Idle: The engine idles erratically, too high, or too low.
- ✔ Communication Issues: Your diagnostic scan tool is unable to communicate with the engine computer, making diagnosis impossible.
The Plug-and-Play Advantage
Our commitment is to provide a seamless and straightforward repair experience. We handle all the complex programming work so you don’t have to.

Frequently Asked Questions
Is this engine computer truly plug-and-play?
Yes, absolutely. We program the module using your vehicle’s VIN before shipping it to you. This service includes loading the correct software and security information, so you can simply install it without needing any special tools or a trip to the dealership.
Where is the ECM located on my 2009 Jeep Commander?
The Electronic Control Module (ECM) on the 2009-2010 Jeep Commander is located in the engine compartment on the right-hand (passenger) side. On the Grand Cherokee, it is in the right-hand rear of the engine compartment.
What information do you need from me to program the module?
To ensure perfect compatibility, we require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. You can typically find the VIN on your dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
Will this fix my specific check engine light codes?
This module is designed to resolve issues related to internal ECM failure, which often cause codes like P0601 (Internal Control Module Memory Check Sum Error) or other processor-related faults. While it can resolve many issues, it’s crucial to properly diagnose your vehicle to ensure the fault lies with the ECM and not a sensor or wiring problem.
Do I need to return my old ECM?
This purchase does not require you to send back your original part. There is no core charge or need to return your old module, saving you time and return shipping costs.
