Sunlight Sensor Test

Turn the ignition switch ON (II). Measure the voltage between the terminals with the (+) probe on the No. 1 terminal and the (-) probe on the No. 2 terminal with the 2P connector connected. 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.
  
• 3.6-3.5 V or less with the sensor in direct sunlight.
