Is Your Jeep Running Rough? It Could Be The Engine Computer.
If your 2009-2010 Jeep Commander or Grand Cherokee with the 3.7L V6 engine is experiencing perplexing issues like stalling, poor fuel economy, a persistent Check Engine Light, or even a no-start condition, the root cause might be a failing Engine Control Module (ECM). The ECM is the central computer of your vehicle, orchestrating everything from fuel injection and ignition timing to transmission shifting. When it begins to fail, it can create a cascade of problems that are often misdiagnosed, leading to wasted time and money on unnecessary repairs.
From the Diagnostic Bay
We had a 2010 Grand Cherokee 3.7L come into the shop that was baffling its owner. It had an intermittent misfire on cylinder 3 that would only happen after the engine was fully warmed up. The owner had already replaced the spark plug, ignition coil, and fuel injector, but the problem persisted. After hours of chasing wires, we hooked up an oscilloscope to the injector control wire at the ECM. We found that the driver circuit inside the original module was failing under heat, cutting power to the injector. A new, correctly programmed ECM solved the problem instantly. It’s a classic example of how a faulty computer can mimic a mechanical failure.
