If you’re dealing with a 2007-2010 Dodge Caliber, Jeep Patriot, or Jeep Compass that’s suddenly developed a mind of its own—stalling, refusing to start, or throwing a cascade of confusing check engine lights—the root cause is often the Engine Control Module (ECM). As a technician with over two decades of experience, I’ve seen how a failing ECM can turn a reliable daily driver into a source of constant frustration. This isn’t just a part; it’s the brain of your vehicle’s engine, and when it falters, nothing works right.
We take the guesswork and high costs out of the repair. This Engine Control Module arrives at your doorstep fully programmed to your vehicle’s specific VIN and mileage. That means no expensive trips to the dealership, no special scan tools, and no complicated programming procedures. It’s a true plug-and-play solution designed to get you back on the road with confidence. By providing a direct-fit, pre-programmed module, we empower you to perform the repair yourself or save your mechanic valuable time, restoring your vehicle’s performance and reliability.
Case Study: A Tricky Diagnosis
I remember a 2009 Caliber that came into the shop with a list of complaints: intermittent stalling at red lights, a flickering electronic throttle control light, and a hard no-start condition on humid mornings. The owner had already replaced the battery and alternator. A quick scan pulled a U0100 (Lost Communication with ECM/PCM) and a P0606 (ECM/PCM Processor Fault). While other modules were flagging communication errors, the root problem was the ECM itself failing internally. Instead of a costly, time-consuming dealer replacement, we installed a pre-programmed unit just like this one. The total time from diagnosis to driving out was under an hour. The vehicle ran perfectly, and all communication codes cleared, proving that the right 2007-2010 Caliber Engine Computer is the key to solving these complex electronic issues.
Common Signs of a Failing Engine Computer
- âś” Check Engine Light is on with communication or processor-related Diagnostic Trouble Codes (DTCs) such as P0601, P0606, or U0100.
- âś” The engine cranks but refuses to start for no apparent reason.
- âś” Unexplained stalling or rough idling, especially after the vehicle has warmed up.
- âś” A noticeable drop in fuel economy or poor engine performance.
- âś” Automatic transmission shifting erratically or harshly.
- âś” Other electronic modules in the vehicle report a loss of communication with the ECM.
A Straightforward Guide to Installation
- âś” Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes before proceeding.
- âś” Locate the ECM: On most Caliber, Patriot, and Compass models, the ECM is located in the engine bay, typically mounted to the firewall or inner fender well.
- âś” Disconnect Connectors: Carefully release the locking tabs on the wiring harness connectors and pull them straight out from the module. Avoid pulling on the wires themselves.
- âś” Remove the Old Module: Unbolt the old ECM from its mounting bracket. It’s usually held in place by a few 8mm or 10mm bolts.
- âś” Install the New ECM: Mount your new, pre-programmed 2007-2010 Caliber Engine Computer in the same location and secure it with the original bolts.
- âś” Reconnect Everything: Firmly plug the wiring harnesses back into the new module until they click into place. Reconnect the negative battery terminal.
- âś” Final Step: Start the vehicle. It may take a moment to idle smoothly as it completes its internal checks. No further programming is required.

Frequently Asked Questions
What does ‘Plug and Play’ actually mean for this ECM?
It means the module arrives pre-programmed with your car’s specific Vehicle Identification Number (VIN) and current mileage. You simply install it, and the vehicle will start and run without needing any additional programming from a dealer or specialized mechanic.
How do I provide my VIN and mileage?
After you place your order, you will be prompted to provide your vehicle’s VIN and mileage. We cannot program and ship the module without this essential information.
Will this fix my specific check engine light codes?
This ECM is a direct solution for internal module failure codes like P0601 (Internal Control Module Memory Check Sum Error) and general processor faults. If you have other codes, ensure you have diagnosed the related sensors or wiring first.
Is this compatible with my original part number?
This unit is compatible with a long list of part numbers, including 05150471AA, 68043260AA, 68028201AC, and 68071022AA. Please check the full compatibility list on this page to confirm your part number is included.
Do I need any special tools for installation?
No special tools are required. Basic hand tools, such as a socket set to remove the mounting bolts and disconnect the battery, are all you need for a successful installation.
