How to Turn Off the Engine Light on a Jeep Libertyby Katebo
When the check engine light illuminates on your Jeep Liberty, it is the result of a problem code being sent from a sensor in the vehicle to the internal On-Board Diagnostics (OBD) computer. It means there is an electrical problem. You should have it looked at and fixed by a qualified mechanic before attempting to reset and turn off the light yourself. Once the problem is fixed, it will be very easy for you to manually reset the light and turn it off.
Find the Diagnostic Link Connector, or DLC, to the right of and underneath the steering column. Plug the scanner into the port and put the key into the ignition. Turn the key to the accessory position.
Plug the pocket scanner into the DLC and then turn the ignition key to the accessory position. Turn on the pocket scanner.
Select "Erase" on the scanner to turn off the check engine light. You will know it worked when you see "Command Sent" or when the screen on the scanner is back to the main menu.
Turn the key to start the engine. The check engine light should now be off. If not, you will need to have the engine looked at again.
- Refer to the owner's manual for the pocket scanner for instructions on how to use it. There are slight variations from manufacturer to manufacturer.
