    • The audio alarm will not operate.
    • The seat belt indicator will not operate.
  3. When the LF seat belt is not buckled, the LF door closed, and the ignition switch is in the RUN position, the following events will occur:
    • The audio alarm will operate for 4 to 8 seconds and then turn OFF.
    • The seat belt indicator will operate for 20 seconds, until the LF seat belt is buckled.
    • The seat belt indicator will flash for an additional 55 seconds before turning OFF.

      To diagnose further failure of the seat belt indicator refer to Symptoms - Seat Belts .
