SENSOR MALFUNCTION CHECK.

1) The A/C switch LED turns off and the sensor inspection is started, after the LED check is completed or when the rear defogger switch is pressed.

2) Switch the air flow control dial to check the sensors.

3) If there is no problem with the sensors, the FRESH/RECIRC switch LED will illuminate, regardless of the position of the air flow control dial.

NOTE:

At this time, the rear defogger LED will light if there are previous failures. For current failures, it will turn off.

It is possible to judge whether there is an open or short circuit by using the blinking patterns of the FRESH/RECIRC switch.

QUESTION

Does the LED of the FRESH/RECIRC switch illuminate?

Yes No

Check the relationship of the air flow control dial position and sensors using the sensor check list, and check/repair sensors that have failed.
