Sun load Sensor
Sun load sensor is a photo diode that detects lights. Resistance
of diode can be measured as current by using multimeter
according to increasing sun loads.
1. Check current on the circuits between the sun load sensor
and the airconditioner control unit.
2. Turn the ignition switch to ON position and check that voltage
between No. 13a terminal of the sun load sensor and vehicle
ground is 5V.
3. Measure current between No. 13a terminal of the sun load
sensor and No. 11 terminal of the control unit and check it is
as shown in the below graph.
4. If current value is out of specification, replace the sun load
sensor.
