3) AQS Operation Circuit
▶AQS sensor
1. Measure the voltage value of AQS.
(between connector terminal No. 3 and 4.)
2. If the measured voltage is out of 0.1 to 4.8 V, replace the AQS.
3. If the measured voltage is out of the specified range, replace the AQS. If it is within the
specified range, check as below.
4.
Turn the ignition key to "ON" position.
5. Measure the voltage between terminal B9 and B15 on the air conditioner controller.
6. 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.
▶Ambient temperature sensor
1. Remove the sensor and measure the resistance between terminal No. 5 and 6 on the
sensor connector.
(standard: approx. 25°C, 2.2 kΩ)
In addition, if the resistance is extremely high or low, replace the sensor.
2. If the measured value is out of the specified range, replace the ambient temperature sensor.
If the measured value is within the specified range, check as below.
3. Turn the ignition switch to ON position and measure the voltage to ambient temperature
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.
