Without DRL

  1. Turn headlights off. Turn ignition on. Set twilight sentinel control to mid position. Cover photocell on top of instrument panel using cardboard. All exterior lighting should come on within 30 seconds.
  2. Uncover photocell. Expose photocell to sunlight or bright incandescent light. All exterior lights should turn off within 30 seconds.
  3. Again cover photocell using cardboard. Wait until exterior lights come on, then turn ignition off. All exterior lights should turn off after a few minutes delay. Delay depends on position of twilight sentinel switch. With switch in MAX position, lights could remain on for about 3-4 minutes. If system performs as described, twilight sentinel system is operating properly. If system does not perform as described, see appropriate TEST PROCEDURE.
