Is Your Jeep Commander or Grand Cherokee Acting Up?
If your 2009 or 2010 Jeep Commander or Grand Cherokee with the 3.7L engine is experiencing frustrating issues like stalling, erratic idling, a persistent check engine light, or a complete no-start condition, a failing Engine Control Module (ECM) is a very likely culprit. The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting. When it begins to fail, it can cause a cascade of problems that are difficult to diagnose and can leave you stranded. Don’t let a faulty computer dictate your vehicle’s reliability. This direct-replacement engine computer is your solution to restore performance and peace of mind.
Expert Pro Tip
Before replacing your ECM, always perform a thorough check of the battery, alternator, and all primary ground connections. A weak battery or a corroded ground strap (especially the one from the engine block to the chassis) can cause voltage drops that mimic the symptoms of a failed ECM. A simple voltage check and cleaning of connection points can sometimes save you the cost and effort of a replacement.
Symptoms of a Failing 2009-2010 Commander Engine Computer
A failing engine computer can manifest in numerous ways. If you’re noticing any of the following, it’s a strong indicator that your ECM needs attention:
- ✔ Unexplained Check Engine Light (CEL) illumination, often with communication-related trouble codes (U-codes).
- ✔ Engine stalling intermittently, especially when coming to a stop or at idle.
- ✔ Rough or unstable idling, making the vehicle shake or feel like it’s about to shut off.
- ✔ Noticeable decrease in fuel economy and overall engine performance.
- ✔ The vehicle cranks but refuses to start for no apparent reason.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Misfire codes that persist even after replacing spark plugs and ignition coils.

Frequently Asked Questions
Is this unit truly “Plug and Play”?
Yes. We program the unit with your vehicle’s VIN and mileage before it ships. This ensures that when you receive it, you can install it directly into your vehicle without any need for additional programming at a dealership or repair shop.
Where is the ECM located on my 2009-2010 Commander or Grand Cherokee?
The Electronic Control Module (ECM) is typically located in the engine compartment. On the Commander and Grand Cherokee, you will find it on the right-hand (passenger) side of the engine bay, often mounted near the firewall or inner fender.
Will I need to have my keys reprogrammed?
No. Because we program the module to your vehicle’s VIN, it will recognize your existing factory keys. The vehicle’s security system will function correctly without any additional steps required.
What causes an engine computer to fail?
ECM failure can be caused by several factors, including electrical shorts from other faulty components, excessive heat, moisture intrusion, or simple age-related degradation of internal electronic components. Voltage spikes from jump-starting a vehicle incorrectly can also damage the module.
What information do you need from me when I order?
To ensure perfect programming, we will need your vehicle’s 17-digit VIN (Vehicle Identification Number) 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.
