Input Test

  1. Remove the gauge assembly from the dashboard (see DASHBOARD REMOVAL/INSTALLATION ), and disconnect the 14P connector from the gauge assembly (see GAUGE/INDICATOR/TERMINAL LOCATION INDEX ).
  2. Inspect the connector and socket terminals to be sure they are all making good contact.
    • If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
    • If the terminals look OK, make the following input tests at the 14P connector.
      • If a test indicates a problem, find and correct the cause, then recheck the system.
      • If all the input tests prove OK, but the indicator is faulty, replace the printed circuit board.
