  2. Turn the ignition switch ON (II). Measure the voltage between the terminals with the (+) probe on the No. 4 (with automatic lighting sensor) or No. 1 (without automatic lighting sensor) terminal and the (-) probe on the No. 2 terminal with the connector connected.
    NOTE: The voltage readings will not change under the light of a flashlight or a fluorescent lamp. Voltage should be:
    • 3.6-3.7 V or more with the sensor out of direct sunlight.
    • 3.3-3.5 V or less with the sensor in direct sunlight.
  3. If the voltage is not as specified, replace the sunlight sensor (see SUNLIGHT SENSOR REPLACEMENT  ).
