How to Reset a Dodge 2002 Computer

by Katebo

A 2002 Dodge generates trouble codes and warning lights on the instrument panel. When these lights are illuminated, your vehicle may require servicing. Most mechanics or dealerships will reset the computer for you after the servicing or repair, but not all. If you have warning or service lights still turned on your dash, then you need to reset the computer yourself. It only takes a few moments of your time and requires no special tools.

Step 1

Locate the fuse panel cover under the steering column. Pull down on it from the top using your fingers.

Step 2

Look for the Electronic Control Unit fuse (ECU) on the fuse diagram, which can be found on the fuse panel cover. Also find the fuse pullers inside the panel.

Step 3

Use the fuse pullers to remove the Electronic Control Unit fuse.

Step 4

Put the key into the ignition and turn the vehicle on, but don't start the engine.

Step 5

Wait five minutes and then put the ECU fuse back in place. The warning and service lights will flash several times on the instrument panel and then turn off. The computer is now reset.

Put the fuse pullers back in place, close up the fuse panel cover and turn off the vehicle.
