Restore Peak Performance to Your 3.7L Jeep
Is your 2009 or 2010 Jeep Grand Cherokee or Commander 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 ECM is the central computer of your vehicle, orchestrating everything from fuel injection and ignition timing to emissions control and transmission shifting. When it falters, the entire vehicle’s performance and reliability are compromised. This replacement Engine Control Module is the definitive solution, engineered to restore your Jeep’s original factory performance and get you back on the road with confidence.
This isn’t just a part; it’s a complete, ready-to-install solution. We take the guesswork and hassle out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN) and current mileage. This critical step ensures that the ECM communicates flawlessly with all other modules in your Jeep, including the security system and transmission controller. The result is a true Plug-and-Play installation—no expensive trips to the dealership for programming, no special tools required. Simply disconnect the old unit, connect this one, and turn the key.
From the Diagnostic Bay
We had a 2010 Grand Cherokee with the 3.7L V6 towed in last month. The owner had spent a fortune chasing a ghost—he’d replaced the crank sensor, cam sensor, and all six coil packs trying to solve an intermittent stalling and no-start problem. The codes were all over the place, pointing to different sensor circuits. After confirming all the sensors and wiring were good, we hooked up our scope to the ECM’s driver circuits for the fuel injectors. We found that the driver for cylinder 3 was dropping out intermittently, starving it of fuel and causing the stall. It was a classic case of internal ECM failure that no amount of external parts could fix. A correctly programmed replacement ECM had the truck running perfectly in under 20 minutes. It’s a powerful reminder that sometimes the problem lies with the brain, not the limbs.
Common Symptoms of a Failing Jeep ECM
- ✔ Persistent and illuminated Check Engine Light (CEL) with various, often inconsistent, trouble codes.
- ✔ Engine stalling unexpectedly or refusing to start at all.
- ✔ Noticeable decrease in fuel economy and poor engine performance.
- ✔ Rough or erratic idling and hesitation during acceleration.
- ✔ Misfire codes (e.g., P0300-P0306) that persist even after replacing spark plugs and coils.
- ✔ Problems with the automatic transmission, such as harsh shifting or not shifting correctly.
- ✔ Communication errors with diagnostic scan tools.

Frequently Asked Questions
Is this engine computer truly “Plug and Play”?
Absolutely. We program the module using your vehicle’s VIN before it ships. This programming includes the necessary immobilizer/security information, ensuring it communicates with your existing keys and other vehicle systems without any need for dealer intervention. Just install it, and you’re ready to go.
What information do you need from me to program it?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) to program the module correctly. You can typically find your VIN on your vehicle’s registration, insurance card, or on the driver’s side dashboard visible through the windshield.
Where is the ECM located on my 2009-2010 Grand Cherokee?
On the 2009-2010 Jeep Grand Cherokee with the 3.7L engine, the ECM is located in the engine compartment, on the right-hand (passenger) side, towards the rear near the firewall. On the Commander, it is also on the right-hand side of the engine compartment.
Do I need to return my old ECM (core)?
This listing does not require a core return. You can keep your old module, which can be helpful if you ever need to reference its part number or for personal disposal.
How can I be sure the ECM is the actual problem?
While the symptoms listed are strong indicators, it’s always best to have a proper diagnosis performed. A qualified mechanic should check for issues with wiring, sensors, and power/ground supplies to the ECM before concluding the module itself is faulty. This ensures you are replacing the correct part the first time.
