Turn the ignition switch OFF.
Disconnect the mode control actuator connector.
Verify that the mode control actuator operates to the defog mode when connecting 12V to the terminal 3 and grounding terminal 7.
Verify that the mode control actuator operates to the vent mode when connecting in the reverse.
1. - 2. - 3. Defrost mode 4. Sensor ground | 5. Feedback signal 6. Sensor (+ 5V) 7. Vent mode |
Connect the mode control actuator connector.
Turn the ignition switch ON.
Check the voltage between terminal 6 and 5.
Door position | Voltage (V) | Error detecting |
Vent | 0.3 ± 0.15 | Low voltage : 0.1V or less |
Defrost | 4.7 ± 0.15 | High voltage : 4.9V or more |
It will feedback the current position of the actuator to the controls.
If the measured voltage is not within specification, substitute with a known-good mode control actuator and check for proper operation.
Replace the mode control actuator if it is proved that there is a problem with it.
Disconnect the negative (-) battery terminal.
Remove the crash pad lower panel.
(Refer to Body -"Crash Pad Lower Panel")
Remove the driver's side shower duct by loosening the screw.
Disconnect the connector (A) and then remove the mode control actuator (B) after loosening the mounting screws.
Install in the reverse order of removal.
