Simply provide us with your vehicle’s VIN and mileage during checkout, and we will professionally program the module. When it arrives at your door, it is 100% plug-and-play, ready for a straightforward installation that gets you back on the road quickly and confidently.

From the Diagnostic Bay

I remember a 2006 Grand Cherokee 3.7L that came into my shop on a tow truck. The owner had spent a small fortune replacing sensors—crank, cam, you name it—trying to solve a random stalling and hard-starting issue. The check engine light was intermittent, and the codes were all over the place. After confirming power and grounds to the ECM were solid, we connected a scope and saw the 5-volt reference signal dropping out randomly. That’s a classic internal failure. We installed a pre-programmed 2005-2006 Grand Cherokee ECM like this one, and the Jeep fired up on the first try and ran perfectly. It’s a textbook example of how chasing symptoms can be costly, while addressing the core problem saves time and money.

Is Your Grand Cherokee Showing These Symptoms?

A failing engine computer can manifest in numerous ways. If you’re experiencing any of the following, a faulty ECM is a likely culprit:

  • ✔ Unexplained Check Engine Light with codes like P0601 (Internal Control Module Memory Check Sum Error), P0605 (Internal Control Module ROM Error), or P0606 (ECM/PCM Processor Fault).
  • ✔ The engine cranks but refuses to start.
  • ✔ Intermittent stalling, especially when the engine is warm or at idle.
  • ✔ Noticeable decrease in fuel economy.
  • ✔ Rough idling or misfiring that isn’t solved by new spark plugs or coils.
  • ✔ Communication issues with diagnostic scan tools.
  • ✔ Problems with the automatic transmission shifting erratically.

A Straightforward Guide to Installation

Replacing the 2005-2006 Grand Cherokee ECM is a job most DIYers can handle with basic tools. Since this unit arrives pre-programmed, you skip the most complicated step. Always consult a repair manual for your specific vehicle, but here is a general guide:

  1. Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow capacitors to discharge.
  2. Locate the ECM: On the 2005-2006 Grand Cherokee, the engine computer is typically found in the engine bay, on the right-hand (passenger) side towards the rear.
  3. Disconnect the Connectors: Carefully release the locking tabs on the wiring harness connectors and pull them straight out from the module. Inspect them for any corrosion or damage.
  4. Remove the Old Module: Unbolt the mounting hardware that secures the old ECM to its bracket. Remove the old unit from the vehicle.
  5. Install the New Module: Mount your new, pre-programmed ECM in the same location and secure it with the original hardware.
  6. Reconnect Everything: Firmly plug the wiring harness connectors back into the new module until they click into place. Reconnect the negative battery terminal.
  7. Final Check: Turn the key to the ‘On’ position for 10-15 seconds before starting the engine. This allows the vehicle’s systems to recognize the new module. Start the engine and check for proper operation.
