Is Your Jeep Commander or Grand Cherokee Experiencing Engine Problems?
Dealing with a malfunctioning engine computer in your 2009-2010 Jeep Commander or Grand Cherokee can be incredibly frustrating. You might be facing a persistent Check Engine Light, rough idling, stalling, or even a complete no-start situation. These issues can sideline your vehicle, disrupt your daily life, and lead to costly and often incorrect diagnoses. The Engine Control Module (ECM), the brain of your vehicle’s engine management system, is frequently the root cause of these perplexing electrical and performance problems. When it fails, it can send incorrect signals to critical components, leading to a cascade of issues that can be difficult to trace.
This replacement Engine Control Module is the definitive solution for your 3.7L Jeep. It arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN) and current mileage. This means there’s no need for expensive trips to the dealership for programming or flashing. It’s a true plug-and-play solution designed to get you back on the road quickly and affordably. By replacing your faulty unit with our pre-programmed module, you restore the precise control and communication your engine needs to operate at its peak efficiency and reliability.
From the Diagnostic Bay
We had a 2009 Grand Cherokee with the 3.7L come in on a tow truck. The owner had already replaced the crankshaft position sensor and the throttle body based on codes P0335 and P2112, but the Jeep would still crank but not start. After confirming fuel pressure and spark, we hooked up our high-level scanner and noticed we couldn’t communicate with the engine module consistently. We’d get a connection, then it would drop. This intermittent communication is a classic sign of internal ECM failure. Instead of chasing more phantom codes, we installed one of our pre-programmed ECMs. The vehicle fired up on the first try and ran perfectly. The customer saved hundreds on further diagnostic time by addressing the core issue: a faulty ECM.

Frequently Asked Questions
Is this ECM truly “plug and play”?
Yes. We program the module to your vehicle’s specific VIN and mileage before shipping. This process syncs the computer with your vehicle’s anti-theft system and other modules, so no additional programming or dealer visit is required upon installation.
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. Always disconnect the battery before attempting removal or installation.
What information do you need from me to program the module?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. You can typically find the VIN on your dashboard (viewable through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my check engine light and running issues?
If the root cause of your problems is a faulty ECM, then this part is the correct solution. However, it is essential to ensure a proper diagnosis has been performed, as other failing sensors or wiring issues can sometimes mimic ECM failure. This module will solve problems directly caused by a failing computer.
Does this part also fit the Jeep Grand Cherokee?
Yes, this ECM is compatible with the 2009-2010 Jeep Grand Cherokee as long as it is equipped with the 3.7L engine. It serves as a direct replacement for the specified part numbers in both models.
