How to Display OBDII Codes on a 2002 Nissan Sentra

You can display the OBD II codes from your 2002 Nissan Sentra on an OBD II pocket scanner. This pocket scanner can be purchased from any auto parts store. These trouble codes contain information about the vehicle to help you pinpoint an exact diagnosis about your Sentras repair and servicing needs. The On-Board Diagnostics computer stores these trouble codes and alerts you to them via warning and service lights that illuminate on your instrument panel. When sensors positioned throughout the vehicle detect any malfunction, they send these codes to the OBD computer.

Instructions

1

Plug the OBD II pocket scanner into the Diagnostic Link Connector (DLC) on the drivers side dash to the left of the steering column, rotating it until it fits properly. Dont force it to go in, or you may bend the pins.

2

Put the key into the ignition, and turn it to the "II" position, taking care not to start the engine. Wait while the OBD II pocket scanner powers on and retrieves the codes. It will display all of the alphanumeric trouble codes on the face of the scanner.

3

Write them down on a piece of paper.

4

Unplug the pocket scanner, and turn off the vehicle when you are finished.
