Circuit Diagram
DescriptionThe In-car air temperature sensor is built in the heater & A/C control unit.The sensor contains a thermistor which measures the temperature of the inside. The signal decided by the resistance value which changes in accordance with perceived inside temperature, is delivered to heater control unit and according to this signal the contr
Inspection1.Turn the ignition switch ON.2.Connect the GDS.3.Emit intensive light toward the photo sensor using a lamp, and check the output voltage change.4.The voltage will rise with higher intensive light and reduce with lower intensive light.1. Auto light signal2.
