(3) Inspection
If the active incar sensor defect code (DTC 1) and the humidity sensor defect code (DTC 10)
are set, check as below:
Air conditioner controller
Air conditioner controller connector
(based on wiring)
▶Active incar sensor
1. Remove the integrated AIH sensor and measure the resistance between terminal No. 5 and
6 on the sensor connector. (standard: approx. 25°C,
2. If the measured value is out of the specified range, replace the AIH sensor. If the measured
values are within the specified range, check as below.
3.
Turn the ignition switch to ON position and measure the voltage to active incar sensor from
the FATC controller connector. (standard: approx. 2 V at 25°C)
4. If the voltage value cannot be measured, check the circuit for open. If the measured value is
within the specified range, replace the FATC controller.
▶Humidity sensor
1. Apply 5 V to terminal No. 1 and 3 on the humidity sensor connector.
2. Connect the positive (+) probe of a tester on No. 2 terminal and the negative (-) probe on
No. 3 terminal, and measure the output voltage while the voltage is applied.
(output voltage: approx. 0.8 ~ 3.4 V)
3.
Check whether the output voltage is changed when blowing into the inlet of the sensor. If
there is a voltage change, the sensor is in normal condition. However, if the voltage is not
changed, replace the humidity sensor.
4. In addition, if the output voltage is extremely high or low even in the specified range, replace
the humidity sensor.
