Restore Peak Performance to Your Jeep’s 3.7L Engine
Is your 2009-2010 Jeep Grand Cherokee or Commander suffering from perplexing engine issues? Unexplained stalling, a persistent Check Engine Light, rough idling, or a complete no-start condition can often be traced back to a failing Engine Control Module (ECM). The ECM is the brain of your vehicle’s engine, and when it malfunctions, it can cause a cascade of frustrating and potentially damaging problems. This direct-fit replacement ECM, part number 68059198AA, is the definitive solution to get your Jeep running reliably again.
From the Diagnostic Bay
We had a 2010 Grand Cherokee with the 3.7L V6 come into the shop that had its owner completely stumped. The vehicle would randomly stall at stoplights and occasionally refuse to start, but there were no consistent trouble codes pointing to a specific sensor. After checking fuel pressure, spark, and all the usual suspects, we hooked up our advanced scanner to monitor live data from the ECM. We noticed the injector pulse width and ignition timing signals were erratic just before a stall. This indicated the processor inside the original ECM was failing. We installed one of our pre-programmed modules, and the Jeep fired right up and ran perfectly. The customer was thrilled to have their reliable vehicle back without an expensive trip to the dealership.
