How to Reset the Engine Light in a Jeep
by KateboThe check engine light on your Jeep will illuminate on the instrument panel when the on-board diagnostics computer receives an error code from a sensor, telling you that something is not working correctly on the vehicle. Although this light is annoying, make sure you take your vehicle to a mechanic to have the trouble code read and the problem repaired before you shut off the light. Once the problem has been fixed, then it will only take you a few minutes at home to reset the light.
Step 1
Find the port under the driver's dashboard that fits the code scanner connector. Plug the scanner into the port, and turn the key in the ignition to the "On" position but don't let the engine start. This will cause the scanner to turn on.
Step 2
Use the arrow keys on the scanner to select "Reset" or "Erase." The check engine light will turn off on the instrument panel.
Step 3
Unplug the scanner, and turn off the vehicle. Wait 10 seconds then turn the engine on. Verify that the check engine light is still off.
