Restore Peak Performance to Your 3.7L Jeep
Is your 2009-2010 Jeep Commander or Grand Cherokee suffering from perplexing issues like a persistent check engine light, rough idling, stalling, or a complete no-start condition? These are classic signs of a failing Engine Control Module (ECM), the central computer of your vehicle. A faulty ECM can disrupt everything from fuel delivery and ignition timing to transmission shifting, leaving you with an unreliable and frustrating driving experience. This direct-fit replacement engine computer, part number 68028166AD, is the definitive solution to restore your Jeep’s original performance and reliability.
From the Diagnostic Bay
We had a 2010 Grand Cherokee 3.7L come into the shop that was a real head-scratcher. The owner had replaced the crank sensor, cam sensor, and even the fuel pump, but it still had an intermittent no-start and would randomly stall while driving. The diagnostic codes were all over the place—communication errors, sensor circuit faults—nothing pointed to one single component. After hours of chasing wires, we decided to inspect the ECM. We found a small amount of corrosion on one of the connector pins that was barely visible. Swapping in a known-good, programmed ECM like this one solved every single issue instantly. It’s a reminder that sometimes the ‘brain’ is the root cause of what seems like multiple unrelated problems.

Frequently Asked Questions
Is this ECM truly Plug and Play?
Yes. We pre-program the module using the VIN you provide. This ensures it has the correct software and security information for your specific vehicle. Once installed, it will function immediately without any additional programming or dealer intervention.
How do I provide my VIN and mileage?
You can enter your Vehicle Identification Number (VIN) and current mileage during the checkout process. Please double-check this information for accuracy, as it is critical for the programming service.
Where is the ECM located on my 2009-2010 Commander?
On the 2009-2010 Jeep Commander with the 3.7L engine, the Electronic Control Module (ECM) is located in the engine compartment on the right-hand (passenger) side, typically mounted to the firewall or inner fender.
What happens if I install an unprogrammed module?
An unprogrammed module will not work. The vehicle’s anti-theft system (SKIM) will prevent the engine from starting, and it will not have the correct operational parameters for your engine and transmission, leading to numerous error codes and poor performance.
Will this fix my transmission shifting issues?
In many cases, yes. The ECM plays a crucial role in controlling the transmission’s shift points and behavior. If the ECM is faulty, it can cause erratic shifting, delayed engagement, or other transmission-related problems. Replacing a bad ECM often resolves these symptoms.
