How to Reset the Fault Code on a Jeep Cherokeeby Jared Curtis
The Jeep Cherokee's engine includes a computer that monitors several sensors. If a sensor reports a problem, the computer will display the check engine light on the dashboard. This tells the driver there is a problem that needs to be assessed. Once the problem is corrected, you can reset the fault codes yourself.
Pull the release lever to open the hood from inside the vehicle. The lever is located underneath the steering wheel on the dashboard.
Open the hood and place the support rod into position to prop up the hood.
Remove the nut connecting the negative battery terminal to the battery, using an open end wrench.
Allow the computer to reset. This will take roughly 30 minutes.
Reconnect the negative terminal to the battery. Tighten the bolt using an open end wrench.
Close the hood and start the engine. If the check engine light re-appears, there is still a problem with the engine that must be addressed.
