Restore Your Vehicle’s Core Performance and Reliability
Dealing with a Dodge Caliber, Jeep Compass, or Patriot that won’t start, runs erratically, or keeps throwing baffling check engine lights? As a mechanic with over two decades of diagnostic experience, I’ve seen firsthand how a failing Engine Control Module (ECM) can be the hidden culprit behind endless frustration. It’s the brain of your vehicle, and when it malfunctions, everything from fuel delivery to spark timing can go haywire. This isn’t just an inconvenience; it can leave you stranded. We offer a dependable and straightforward solution: a replacement ECM, part number 68000112, that arrives at your door fully programmed and ready for installation.
A Technician’s Notebook
I remember a 2009 Caliber that came into the shop with an intermittent no-start condition that had two other shops stumped. It would crank but wouldn’t fire, and the only consistent code was a U0100 (Lost Communication with ECM). After verifying power and ground at the module connectors were solid—a critical first step—we suspected an internal ECM failure. The module would heat up and lose its ability to communicate. Swapping in a pre-programmed unit like this one had the car starting reliably every single time. The customer went from considering selling the car to having their daily driver back in less than an hour of work.
Is Your Vehicle Showing These Telltale Symptoms?
A failing engine computer can manifest in numerous ways. If you’re experiencing any of the following, a faulty ECM is a likely cause. Look out for these signs and associated Diagnostic Trouble Codes (DTCs):
- ✔ Complete no-start or no-crank condition.
- ✔ Engine stalls randomly while driving.
- ✔ Poor fuel economy and rough idling.
- ✔ Check Engine Light is on with codes like P0601 (Internal Control Module Memory Check Sum Error), P0606 (ECM/PCM Processor Fault), or various communication codes (U-codes).
- ✔ Inconsistent or no communication with your scan tool.
- ✔ Apparent transmission shifting problems, as the ECM communicates with the TCM.

A Straightforward Guide to Installation
Installing your new engine computer is a manageable job for a DIYer with basic tools. Following these steps ensures a smooth process. Always prioritize safety!
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all capacitors to discharge.
- Locate the ECM: On most Caliber, Compass, and Patriot models, the ECM is located in the engine bay, typically mounted to the firewall or inner fender. It’s a metal box with several large electrical connectors.
- Disconnect the 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.
- 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.
- Install the New Module: Mount your new, pre-programmed ECM in the same location and secure it with the original bolts.
- Reconnect Everything: Firmly plug the wiring harness connectors back into the new ECM until they click into place. Reconnect the negative battery terminal.
- Final Check: Turn the key to the ‘ON’ position (without starting the engine) for 30 seconds to allow the system to initialize. Then, start your vehicle. It should fire up and run smoothly.
