Once you've read the diagnostic code and finished the needed repairs on your Toyota Camry, you must reset the On-Board Diagnostic fault codes. Comparatively speaking, this task is almost an afterthought, as it is not as time-consuming as looking up a code definition and performing the repairs. However, you cannot forget to reset the codes, because if you do, the "Check Engine" light will remain lit on the dashboard.

  1. 1

    Hook the code scanner into the Camry's diagnostic port beneath the steering wheel. This is the same port you used to retrieve the codes.

  2. 2

    Turn on the scanner.

  3. 3

    Turn on the car.

  4. 4

    Wait for the trouble code to appear on the scanner's screen. This should take only a few seconds.

  5. 5

    Press the "Erase" button on the scanner.

  6. 6

    Turn the car and scanner off. Disconnect the scanner from the diagnostic port.

  7. 7

    Turn on the Camry's electrical system. Look at the dashboard. The "Check Engine" light should be dark. If it isn't, reconnect the scanner to see if there is a new code there or simply erase the code again.

Tips and warnings

  • OBD-II codes are good only for vehicles made after 1996. Vehicles predating that year operate under a different diagnostic code.
  • Trouble codes light the "Check Engine" for a reason: to get your attention. If you ignore the light or reset the diagnostic system without reading the code, you could unwittingly cause bigger repairs later.
