Signal Waveform
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the HO2S connector. 3. Measure resistance between the HO2S terminals 1 and 2. 4.
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the console temperature control actuator connector. 3. Verify that the console temperature control actuator operates to the defrost mode when connecting 12V to terminal 3 and grounding terminal 4.
Description The auto defogging sensor is installed on front window glass. The sensor judges and sends signal if moisture occurs to blow out wind for defogging. The air conditioner control module receives a signal from the sensor and restrains moisture and eliminates defog by the intake actuator, A/C, auto defogging actuator, blower motor
