Is Your Grand Cherokee Stalling, Running Rough, or Refusing to Start?
As a technician with over two decades of experience, I’ve seen countless 2005-2006 Jeep Grand Cherokees with the 3.7L engine roll into the bay with frustrating and often intermittent issues. The culprit is frequently a failing Engine Control Module (ECM). Symptoms can range from a persistent check engine light and poor fuel economy to sudden stalling at intersections or a complete no-start condition, leaving you stranded. This isn’t just an inconvenience; it’s a critical failure of your vehicle’s central computer.

This ECM, part number 56044547AF, arrives at your door fully programmed to your vehicle’s specific VIN and mileage.

“A customer’s 2006 Grand Cherokee 3.7L 4×4 came into my shop last month. It had intermittent stalling and a P0601 (Internal Control Module Memory Check Sum Error) code that wouldn’t clear. After confirming power and ground at the ECM connector were solid, we knew the module itself was the issue. We swapped in one of these pre-programmed units, and the problem was solved in under 30 minutes. The key is ensuring the VIN is correct during checkout to avoid any communication issues.”

Plug-and-Play Installation: No Dealer Visit Required
Replacing the ECM on your WK Grand Cherokee is a job you can handle in your own driveway. The module is located in the engine compartment on the passenger’s side (RH side), near the firewall.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes for the system capacitors to discharge.
- Locate the ECM: Open the hood and find the ECM on the right-hand (passenger) side rear of the engine compartment.
- Disconnect the Wiring: Carefully release the locking tabs on the electrical connectors and pull them straight out from the module. Inspect the connectors for any corrosion or bent pins before proceeding.
- Remove the Old Module: Unbolt the mounting hardware holding the original ECM in place and remove it from the vehicle.
- Install the New ECM: Mount your new, pre-programmed ECM in the same location and secure it with the original hardware.
- Reconnect Everything: Firmly plug the wiring harnesses back into the new module until they click into place. Reconnect the negative battery terminal.
- Final Check: Turn the key to the ‘ON’ position (without starting the engine) for 10-15 seconds to allow the systems to initialize. Then, start your engine. Your Grand Cherokee should now run smoothly.
