How to Turn Off Service Engine Soon Light on 2002 Ford Pickup

A 2002 Ford pickup is equipped with an On-Board Diagnostic II (OBD II) computer. This computer reads trouble codes sent from sensors positioned throughout the vehicle, and it keeps track of when the pickup needs to be serviced. When you see the Service Engine Soon light illuminate on your instrument panel, this is information being sent to you from the vehicles computer. Make sure you service the engine first before you attempt to reset and turn off the light. Otherwise the light will just keep turning back on and it wont accurately keep track of when your vehicle needs servicing.

Instructions

1

Lift up the hood of the pickup and prop it open. Remove the battery cable from the negative side of the battery using a 1/2-inch end wrench. Let the truck sit for about five minutes. Put the cable back in place and close the hood.

2

Put the key into the ignition and start the engine. Look at your instrument panel to see if the Service Engine Soon light turned off. If it didnt turn off, go to an auto parts store and buy an OBD-II code scanner to reset the light.

3

Plug the connector on the OBD-II code scanner into the port to the left under the steering column. Put the key into the ignition and turn the car on but dont start the engine. Key into your scanner your pickups make, model and engine size.

4

Wait for the trouble code for Service Engine Soon to appear on the scanner. When it does, press "delete." Remove the scanner from the port and start the engine. The light should now turn off.
