Mode Control Actuator: 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.
[Driver/Passenger]
- Connect the mode control actuator connector.
- Turn the ignition switch ON.
- Check the voltage between terminal 5 and 4.
Door Position Voltage (V) Error detecting VENT 0.3 ± 0.15V Low voltage: 0.1V or less High voltage: 4.9V or more DEFROST 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.
