To address potential issues, you need to clarify what you want to reset:
* The Check Engine Light (CEL): This light indicates a problem detected by the On-Board Diagnostics (OBD) system. You can't simply reset it; you need to *diagnose and fix the underlying problem*. A mechanic can use an OBD code reader to determine the cause of the CEL. Simply clearing the code without fixing the issue will cause it to reappear.
* The PCM (Powertrain Control Module): This is the closest thing to a "computer" in your Jeep. There's no user-accessible reset button. A mechanic might be able to reset it using specialized diagnostic tools if there's a software glitch, but this is rare. Problems usually point to a faulty sensor or other component rather than a software issue.
* The Radio or Other Electronics: If you're having issues with the radio presets or other electrical components, you might find a small reset button on the device itself (e.g., on the radio). Consult your owner's manual for specifics. Disconnecting the battery for a short time (10-15 minutes) can also sometimes reset electronic modules. Remember to disconnect the negative (-) terminal first.
* Something Else: If your issue isn't one of the above, please be more specific about the problem you're experiencing. This will help in determining the appropriate troubleshooting steps.
In short, there's no single "reset computer" button. You'll need to identify the specific problem before you can find a solution.
