Sunlight Sensor Test

NOTE: Before testing the sensor, check for climate control DTCs (see HOW TO CHECK FOR DTCS WITH THE HDS ).

Remove the sunlight sensor (A) (see SUNLIGHT SENSOR REPLACEMENT ).

Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode. Measure the voltage between terminals with the (+) probe on terminal No. 4 and the (-) probe on terminal No. 2 with the connector connected.
NOTE: The voltage readings do not change under the light of a flashlight or a fluorescent lamp. Voltage should be:
- 3.56 V with no sunlight or the sensor covered up
- Less than 3.56 V with the sunlight on sensor (depending on sunlight intensity)
If the voltage is not as specified, replace the sunlight sensor (see SUNLIGHT SENSOR REPLACEMENT ).
