Restore Your Jeep’s Performance and Reliability
Is your 2005 or 2006 Jeep Grand Cherokee suffering from frustrating and unpredictable issues? A persistent check engine light, sudden stalling, rough idling, or a complete no-start condition can all point to a failing Engine Control Module (ECM). Don’t let a faulty computer keep your capable SUV sidelined. This professionally programmed 2005-2006 Jeep Grand Cherokee ECM is the definitive, hassle-free solution to get you back on the road with confidence.
Common Symptoms of a Failing ECM & Your Direct Solution
A failing engine computer can manifest in numerous ways, often mimicking other sensor failures and leading to frustrating, expensive diagnostics. If you’re experiencing any of the following, your ECM is the likely culprit:
- Check Engine Light: Particularly with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0605, or P0606.
- No-Start Condition: The engine cranks but refuses to start due to a lack of fuel or spark command from the ECM.
- Erratic Engine Behavior: Unexplained stalling, stumbling, hesitation, or surging during acceleration.
- Poor Fuel Economy: The engine is not receiving the correct parameters for efficient operation.
- Automatic Transmission Issues: Harsh shifting or failure to shift, as the ECM communicates directly with the transmission controller.
This unit is your direct-fit, plug-and-play fix. We take the guesswork out of the repair by programming the module to your vehicle’s specific VIN and mileage before it ships. This means no expensive trips to the dealership for additional programming are required.

Expert Insight from the Shop Floor
We recently worked with a customer whose ’06 Grand Cherokee had an intermittent no-start problem that two different shops couldn’t diagnose. They had replaced the crank sensor and fuel pump with no success. The issue was a hairline crack in the ECM’s circuit board that only caused a fault when the engine bay reached a certain temperature. Installing a pre-programmed 2005-2006 Jeep Grand Cherokee ECM like this one solved the problem instantly. Proper diagnosis is key, and when the signs point to the computer, a reliable, pre-programmed unit is the fastest path to a permanent fix.
Frequently Asked Questions
Is this unit truly “Plug & Play”?
Yes. We use the VIN you provide during checkout to flash the unit with your vehicle’s exact software and security information. This ensures it communicates perfectly with your Jeep’s existing modules right out of the box, with no further programming needed.
How do I provide my VIN and mileage?
You will be prompted to enter your vehicle’s VIN and current mileage during the checkout process. Please double-check this information for accuracy, as it is critical for correct programming.
Where is the ECM located on my 2005-2006 Grand Cherokee?
The ECM on this model is typically located in the engine compartment, on the right-hand (passenger) side, near the firewall. It is a silver metal box with several large electrical connectors.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original ECM (such as code P0601), this replacement 2005-2006 Jeep Grand Cherokee ECM is designed to resolve the issue. However, if the light is on due to other failing sensors or components on the vehicle, those issues will need to be addressed separately.
Do I need to have my keys reprogrammed?
No. Because we program the module to your specific VIN, it will recognize your existing factory keys. This is a major benefit that helps you avoid additional locksmith or dealer fees.
What does the one-year replacement warranty cover?
Our warranty covers any internal defects or programming issues with the unit itself for a full year from the date of purchase. If the unit fails within that period, we will provide a replacement. The policy does not cover damage from improper installation or failures caused by other vehicle faults.
