Restore Peak Performance to Your Jeep
Is your 2005 or 2006 Jeep Grand Cherokee suffering from frustrating issues like intermittent stalling, a persistent check engine light, rough idling, or a complete no-start condition? These are classic signs of a failing Engine Control Module (ECM). As the brain of your vehicle, a faulty ECM can cause a cascade of problems that are often difficult to diagnose. This module is the definitive solution, arriving at your door fully programmed to your vehicle’s specific VIN and mileage, making for a straightforward, Plug & Play installation.
From the Diagnostic Bay
I remember a 2006 Grand Cherokee with the 3.7L that came into my shop on a tow truck. The owner had already replaced the crank and cam sensors, chasing an intermittent no-start problem. The engine would crank but never fire. When it did run, it would occasionally stall at red lights. After scanning, I found a P0601 (Internal Control Module Memory Check Sum Error). This code is a dead giveaway for internal PCM failure. We installed one of our pre-programmed modules, and the Jeep fired up on the first try and ran perfectly. This simple swap saved the customer from a costly dealership visit and the headache of further incorrect diagnostics.
