Outer temperature/humidity sensor is defective.
► Troubleshooting method
• A3–3310 / A3–3311 / A3–3312 : Temperature function is abnormal.
• A3–3410 / A3–3411 / A3–3412 : Humidity function is abnormal.
1) Enter SVC mode. Execute sensor test to check the sensor operation. (Diagnostics > Engine Diagnostics > Engine
Test Routines > 109-0013 Outer Temperature )
2) Remove the left cover.
(Refer to 3.3.4 Temperature Sensor)
Measure the resistance value of the connector at both ends.
If the value is not in 47.5KΩ ~ 52.5KΩ (@ 25 ℃), replace the sensor(JC93-00486A).
3) If the harness and sensor are normal, replace the main board (JC92-02429A).
