How to Reset Check Engine Lights in 2003 Subaru Foresters

by Katebo

Subaru is a Japanese company that started manufacturing the Foresters back in 1997. The on-board diagnostics computer will illuminate the "Check Engine" light on the instrument cluster when it detects a malfunction from one of the sensors in the emissions system or in the engine. You need a scan tool to read the trouble code generated by the computer. This tool can be obtained from any auto parts store. Once the code has been read and the problem fixed, you may still need to reset the light and shut off the "Check Engine" light. This can be done without the use of any special tools and it should only take you about 10 minutes to complete the task.

Find the fuse panel cover on the driver's side dashboard and pull it open with your fingers.

Put the key into the ignition and turn it to "Run."

Locate and remove the fuse pullers within the fuse panel. Look on the inside of the fuse panel cover and locate the ECU fuse. Pull this fuse out of the fuse box using the fuse pullers.

Wait about five minutes and the put the ECU fuse back in place.

Turn the vehicle on and verify that the "Check Engine" light has shut off.
