Is Your 2009-2010 Jeep Grand Cherokee Running Rough?
If your Jeep Grand Cherokee or Commander with the 3.7L engine is experiencing frustrating issues like stalling, poor fuel economy, erratic shifting, or a persistent check engine light, 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 control. When it starts to fail, it can cause a cascade of problems that are difficult to diagnose and can leave your vehicle unreliable or completely inoperable.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light is on with codes related to sensors, communication, or processor faults.
- ✔ Engine cranks but refuses to start.
- ✔ Unexplained stalling or rough idling.
- ✔ Noticeable decrease in engine power and acceleration.
- ✔ Poor fuel mileage.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Communication issues with diagnostic scan tools.
Expert Pro Tip
Before replacing your ECM, always perform a thorough check of the vehicle’s battery, charging system, and all main power and ground connections to the module. A corroded ground wire or a weak battery can mimic the symptoms of a failed ECM, leading to a costly misdiagnosis. Use a multimeter to verify you have a stable 12V+ supply and a solid ground path at the ECM connector pins before condemning the unit.
