If you’re dealing with a 2007-2010 Dodge Caliber, Jeep Patriot, or Jeep Compass that’s running rough, stalling unexpectedly, or simply won’t start, a failing Engine Control Module (ECM) is often the culprit. I’ve spent years in the service bay tracing these exact issues, and I know how frustrating intermittent electrical problems can be. This isn’t just a part; it’s the solution to get your vehicle running reliably again, without the astronomical costs and scheduling headaches of a dealership visit.
This ECM, part number 68044228AA, arrives at your door completely pre-programmed to your vehicle’s specific VIN and mileage. This is the critical step that makes the entire process simple. Forget about needing expensive scan tools or paying for programming services. This is a true plug-and-play fix designed for both professional mechanics who value efficiency and DIY enthusiasts who want a dependable repair they can perform in their own driveway.
Understanding the Role of Your 2007-2010 Caliber Engine Computer
Think of the ECM as the brain of your vehicle’s engine. It constantly analyzes data from sensors across the engine and drivetrain to manage everything from fuel injection and spark timing to transmission shift points and emissions controls. When this central computer starts to fail, it can create a cascade of confusing and often unpredictable symptoms. Our replacement module restores this critical functionality, ensuring all systems operate in perfect harmony as the manufacturer intended.
Case Study: A Tricky Diagnosis
A customer brought in a 2009 Jeep Patriot with a complaint that stumped two other shops: it would randomly stall at traffic lights, but only when the A/C was on. There were no consistent trouble codes, just a history of random communication faults. After confirming the battery and alternator were solid, we focused on the ECM. On these Chrysler platforms, the ECM can develop internal faults under specific load conditions. We swapped in a pre-programmed ECM, and the problem vanished instantly. It’s a perfect example of how a failing computer can cause bizarre, hard-to-diagnose symptoms that a direct replacement solves immediately.
Common Signs of a Failing Engine Computer
- âś” The Check Engine Light is on or flashing with codes like P0601 (Internal Control Module Memory Check Sum Error), P0606 (ECM/PCM Processor Fault), or U0100 (Lost Communication With ECM/PCM).
- âś” Your vehicle has difficulty starting or won’t start at all, even with a good battery.
- âś” The engine stalls, sputters, or idles erratically for no apparent reason.
- âś” You notice a sudden and significant drop in fuel economy.
- âś” The automatic transmission is shifting harshly or at the wrong times.
- âś” Other warning lights (like the electronic throttle control) illuminate on the dash.
A Straightforward Guide to Your ECM Installation
- âś” Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes for the system capacitors to discharge before beginning any work.
- âś” Locate the ECM: On most 2007-2010 Caliber, Patriot, and Compass models, the ECM is located in the engine bay, typically mounted to the firewall or inner fender.
- âś” Disconnect the Connectors: Carefully release the locking tabs on the electrical wiring harnesses and pull them straight out from the module. Never force them. Inspect the connectors for any corrosion or damage.
- âś” Remove the Old Module: Unbolt the old ECM from its mounting bracket. There are usually a few 8mm or 10mm bolts holding it in place.
- âś” Install the New Module: Mount your new, pre-programmed ECM in the same location and secure it with the original bolts.
- âś” Reconnect Everything: Plug the wiring harnesses back into the new module until they click securely into place. Reconnect the negative battery terminal.
- âś” Final Step: Start the engine. The vehicle will now run with the correct programming for your specific VIN. No further action is needed!

Frequently Asked Questions
Do I really need to provide my VIN?
Yes, providing your VIN is essential. We use it to load your vehicle’s exact software and security information onto the module, which makes it a true plug-and-play part and ensures it communicates correctly with your car’s other systems.
Is this difficult to install for a DIYer?
Not at all. If you are comfortable using basic hand tools like a wrench or socket set, you can do this job. The most important part is handled by us—the programming. You are simply swapping the physical component.
Will this fix my transmission shifting problems?
In many cases, yes. The ECM works directly with the transmission control module (TCM) to regulate shifting. If the ECM is sending bad data, it can cause poor shifting performance. Replacing a faulty ECM often resolves these related issues.
What if my original part number isn’t on your list?
Our compatibility list is extensive, but not exhaustive. If your part number is different, please contact us with your vehicle’s VIN. We can verify compatibility and ensure you receive the correct module for your application.
Is any other programming needed after I install it?
No. The module is fully programmed for your vehicle before it ships. Once you install it and reconnect the battery, you can start the car and drive. No trip to the dealer or a mechanic for programming is required.
