The 1998 Acura Integra comes with a theft-deterrent radio. Because of this, disconnecting the battery to reset the "check engine" light will work, but you'll also lose your radio code if you do so. This makes the radio inoperable until it is reprogrammed with the correct radio code. If you do not have the radio code, it may well have to be pulled out of the dash to obtain, which is labor-intensive. Through OBD II (on-board diagnostic two, which was implemented in 1996 and newer vehicles), there is a much easier way to reset the code.

Reset Check Engine Light[edit]

  • Open the passenger side door to the Integra to locate the data link connector (DLC). It is below the glove box, just behind the center console.
  • Connect the unique-shaped OBD II scan tool plug into the DLC. Because of its shape, there's only one way to connect it properly.
  • Place the key into the ignition of the Integra and turn it to the key-on/engine-off position.
  • Refer to the manual of the scan tool for directions on how it works. With so many varieties of scan tools on the market, some offer completely different features. However, they're quite easy to use as long as you follow the commands of the menu on the face of the tool.
  • Erase the code according to the directions of the manual (some models even feature an erase button; simply pressing it will erase the code).
  • Wait for the onscreen menu to inform you that the command has been sent or the main menu has reappeared before turning the key back to the "off" position and unplugging the unit.
  • Switch over to the driver's seat and then start the engine of the Integra to ensure the "check engine" light is no longer displayed on the instrument panel.

Tips & Warnings[edit]

  • Be sure not to reset the "check engine" light in the Integra unless the trouble code has been diagnosed first and, if necessary, repaired. Otherwise, more problems can occur.
