Inspection
1. | Ignition "OFF”
2. | Disconnect the connector of mode control actuator.
3. | Verify that the mode control actuator operates to the defrost mode when connecting 12V to the terminal 3and grounding terminal 4.
4. | Verify that the mode control actuator operates to the vent mode when connecting in the reverse.
1. - 2. - 3. Defrost mode 4. Vent mode | 5. Sensor ground 6. Feedback signal 7. 5V(Vcc)
5. | Check the voltage between terminals 5 and 6.
Door position | Voltage (5-6) | Error detecting
Vent | 0.3 ± 0.15V | Low voltage :0.1V or less
Defrost | 4.7 ± 0.15V | High voltage :4.9V or more
It will feedback current position of actuator to controls.
6. | If the measured voltage is not specification, substitute with a known-good mode control actuator and check for proper operation.
7. | If the problem is corrected, replace the mode control actuator.
Replacement
1. | Disconnect the negative (-) battery terminal.
2. | Remove the crash pad left side cover (A).
3. | Remove the extension cover(A)
4. | Remove the crash pad lower cover (A).
5. | Disconnect the diagnosis connector (A).
6. | Remove the reinforcing panel (A).
7. | Remove the shower duct (A).
8. | Disconnect the temperature control actuator connector (A).
9. | Loosen the mounting screw and then remove the temperature control actuator (B).
10. | Installation is the reverse order of removal.
