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. 5V(Vcc) 6. Feedback signal 7. Sensor ground |
Ignition "OFF”
Disconnect the connector of mode control actuator.
Verify that the mode control actuator operates to the defrost mode when connecting 12V to the terminal 3and grounding terminal 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. 5V(Vcc) 6. Feedback signal 7. Sensor ground |
Check the voltage between terminals 6 and 7.
Door position | Voltage (5-6) | Error detecting |
Vent | 0.45 ± 0.15V | Low voltage :0.1V or less |
Defrost | 4.55 ± 0.15V | High voltage :4.9V or more |
It will feedback current position of actuator to controls.
If the measured voltage is not specification, substitute with a known-good mode control actuator and check for proper operation.
If the problem is corrected, replace the mode control actuator.
