Repair Procedures: Inspection
- Turn the ignition switch OFF.
- Disconnect the mode control actuator connector.
- Verify that the mode control actuator operates to the defrost mode when connecting 12V to terminal 7 and grounding terminal 3.
Verify that the mode control actuator operates to the vent mode when connected in reverse.
- 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 ± 0.15V Low voltage: 0.1V or less
High voltage: 5.0V or lessDefrost 4.7 ± 0.15V * It will feedback the current position of the actuator to 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.
