The Direct Solution for Your Jeep or Dodge
If you’re dealing with frustrating and unpredictable issues in your 2007-2010 Jeep Compass, Patriot, or Dodge Caliber, a failing Engine Control Module (ECM) is often the culprit. From a car that won’t start to erratic engine behavior, a faulty computer can turn your reliable vehicle into a source of constant stress. This replacement engine computer, part number 04692101AF, is the definitive, hassle-free solution. We take the guesswork and complexity out of the repair by programming the module specifically to your vehicle’s VIN and mileage before it even ships. This means no expensive trips to the dealership for programming—it arrives at your door ready for a straightforward, plug-and-play installation.
Case Study: The Ghost in the Machine
A customer brought in a 2009 Dodge Caliber with a 2.0L engine that was driving him crazy. It would stall randomly at red lights, sometimes refuse to start in the morning, and had a persistent Check Engine Light. He’d already replaced the spark plugs and a sensor with no luck. After connecting my scan tool, I pulled a P0601 code—Internal Control Module Memory Check Sum Error. This code is a direct indictment of the PCM itself. Instead of a costly dealer replacement, we ordered a pre-programmed unit like this one. The swap took less than 30 minutes in the bay, and the car fired right up and ran perfectly. The pre-programming saved my customer hundreds and got his car back on the road the same day.
Is Your Vehicle Showing These Symptoms?
A failing ECM can manifest in numerous ways. Over my 20+ years in the shop, I’ve seen these modules cause a wide range of problems. Here are the most common signs that your engine computer needs replacement:
- ✔ Complete no-start or intermittent starting issues.
- ✔ Engine stalling unexpectedly while driving or at idle.
- ✔ Rough running, misfires, or a noticeable loss of power.
- ✔ Poor fuel economy that can’t be explained by other factors.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Check Engine Light is on with codes like P0601, P0606, or U0100.
- ✔ Cooling fans running constantly or not turning on at all.
A Straightforward Guide to Installation
One of the biggest benefits of this module is its simple installation. Because we handle all the programming, you can perform the replacement with basic hand tools right in your driveway. This is a perfect job for a DIY enthusiast looking to save on labor costs.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to fully discharge.
- Locate the ECM: On most Compass, Patriot, and Caliber 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 and Remove: Carefully unplug the wiring harnesses from the old module. There are usually release tabs you’ll need to press. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed ECM into place. Securely reconnect the wiring harnesses, ensuring they click and lock into position.
- Final Step: Reconnect the negative battery terminal. The vehicle is now ready to start. No further programming or relearn procedures are required.

Frequently Asked Questions
What information do you need to program the computer?
What information do you need to program the computer?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. This ensures the ECM is a perfect match for your vehicle’s specific configuration and security systems.
Is this really ‘Plug and Play’?
Yes. ‘Plug and Play’ means the unit arrives fully programmed and requires no additional work after installation. Simply install the part, connect the battery, and start your vehicle. All necessary security information and vehicle parameters are pre-loaded.
Will this fix my transmission problems?
In many cases, yes. The Engine Control Module works closely with the transmission controller. If the ECM is failing, it can send incorrect data, leading to poor shifting, delayed engagement, or other transmission-related symptoms. Replacing a faulty ECM often resolves these issues.
Do I need to return my old engine computer?
No core charge or return is required for this part. You can keep your old module or recycle it locally.
How do I confirm this is the right part for my car?
The best way is to match the part number from your existing module to the list of compatible numbers on this page. If you’re unsure, check the fitment list or contact us with your VIN, and we’ll be happy to verify compatibility for you.
