Restore Peak Performance to Your 3.7L Jeep
Is your 2009 or 2010 Jeep Grand Cherokee or Commander suffering from perplexing issues like poor fuel economy, rough idling, stalling, or a dreaded check engine light that won’t go away? These are classic signs of a failing Engine Control Module (ECM). The ECM is the electronic brain of your vehicle, orchestrating everything from fuel injection and spark timing to transmission shifting and emissions control. When it starts to fail, the symptoms can be unpredictable and frustrating, often mimicking other mechanical problems. Don’t let a faulty computer keep your reliable Jeep off the road. This direct-fit replacement ECM is the definitive solution to restore your vehicle’s original performance and reliability.
The Easiest Solution for a Complex Problem
Replacing an ECM has traditionally been a costly and inconvenient process, requiring a trip to the dealership for expensive programming. We eliminate that hassle completely. This module arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN) and mileage. This means it is a true Plug & Play solution. Simply disconnect the battery, swap the old module with this one, reconnect the battery, and you’re ready to go. No specialized tools, no trips to the mechanic, and no additional programming fees are required. It’s the most efficient way to get your Jeep running right again.
From the Diagnostic Bay
We had a 2010 Grand Cherokee with the 3.7L come in with a complaint of harsh, erratic shifting and a persistent check engine light for a transmission solenoid circuit. The owner had already replaced two solenoids in the valve body with no change. Our technician suspected something else was at play. After running a full diagnostic, we found that the ECM was sending faulty voltage signals to the transmission control module (TCM), causing it to misinterpret data and command harsh shifts. The root cause wasn’t the transmission at all, but the engine’s main computer. We installed a VIN-programmed ECM, cleared the codes, and the Jeep shifted perfectly. It’s a powerful reminder that the ECM’s health is critical to the entire vehicle’s operation, not just the engine.

Frequently Asked Questions
Is this ECM really “Plug and Play”?
Yes, absolutely. We program the module with your vehicle’s VIN and mileage before it ships. This ensures that it will integrate seamlessly with your Jeep’s existing systems, including the anti-theft (SKIM) system, without any need for a trip to the dealership for additional programming.
Where is the ECM located on my 2009-2010 Grand Cherokee?
On the 2009-2010 Jeep Grand Cherokee, the Electronic Control Module is located in the engine compartment, on the right-hand (passenger) side, towards the rear near the firewall.
How do I know if my original ECM has failed?
Diagnosing a faulty ECM can be tricky, but common indicators include a persistent check engine light, stalling, poor engine performance, communication issues with scan tools, and multiple unrelated error codes. It’s always best to have a qualified mechanic perform a full diagnostic, but if you are experiencing several of the symptoms listed above, a failing ECM is a likely culprit.
Will this also fit my 2009-2010 Jeep Commander with the 3.7L engine?
Yes, this module is also the correct fit for the 2009-2010 Jeep Commander equipped with the 3.7L engine. The ECM is located in the right-hand (passenger) side of the engine compartment on the Commander as well.
