Restore Peak Performance to Your Jeep
Is your 2009 or 2010 Jeep Grand Cherokee or Commander suffering from baffling engine issues? Stalling, rough idling, a persistent check engine light, or a complete no-start condition can often be traced back to a failing Engine Control Module (ECM). This component is the brain of your vehicle’s engine, and when it malfunctions, it can cause a cascade of frustrating and performance-robbing problems. This replacement engine computer, part number 68028151, is the definitive solution to get your 3.7L Jeep running like new again.
Identifying a Faulty 2009-2010 Grand Cherokee ECM
Diagnosing an ECM failure can be tricky, as its symptoms often mimic other component failures. However, if you’re experiencing several of the issues below, the ECM is a primary suspect. A faulty module can disrupt everything from fuel delivery and ignition timing to transmission shifting and emissions control. Ignoring these signs can lead to further damage, poor fuel economy, and failed emissions tests.
From the Diagnostic Bay
We had a 2010 Grand Cherokee with the 3.7L towed in last month. The owner had already replaced the spark plugs, coil packs, and even a fuel injector trying to chase down a random, intermittent misfire and stalling issue. The check engine light would come and go. After hours of diagnostics, we checked the power and ground signals at the ECM connector. We found a solid ground but an inconsistent voltage reading on one of the main power feeds. Before condemning the module, we traced the wiring harness and found a corroded section near the battery tray. A simple wiring repair fixed the issue. This is a crucial reminder: always verify the integrity of your grounds and power connections to the ECM before replacing the unit. A simple check can save you hundreds of dollars.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns immediately.
- ✔ Engine stalling or shutting off unexpectedly while driving.
- ✔ Rough or erratic idling.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Engine misfires or stumbling during acceleration.
- ✔ Vehicle entering ‘limp mode’ with reduced power.
- ✔ Complete no-start condition where the engine cranks but won’t fire.
- ✔ Automatic transmission shifting issues or harsh engagement.
- ✔ Communication errors with diagnostic scan tools.

Frequently Asked Questions
Is this ECM really plug and play?
Yes, absolutely. We program the module with the specific VIN and mileage you provide. This ensures it communicates correctly with your Jeep’s other systems, including the ignition and security, right out of the box. No further dealer programming is required.
What information do you need from me to program it?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. You can typically find the VIN on your driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
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. On the Commander, it is also on the right-hand side of the engine compartment.
How do I know for sure that my ECM is the problem?
While the symptoms listed are strong indicators, a definitive diagnosis is always best. A qualified mechanic can perform tests to confirm the ECM is at fault. This often involves checking for diagnostic trouble codes (DTCs), verifying power and ground signals at the ECM connector, and ruling out other potential causes like wiring issues or failed sensors.
Do I need to perform a ‘relearn’ procedure after installation?
In most cases, no special relearn procedure is needed. After installing the new ECM and reconnecting the battery, you may want to let the vehicle idle for 5-10 minutes to allow the internal systems to acclimate. Driving the vehicle for 15-20 miles will typically allow all systems to self-calibrate.
