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. 5V (Vcc) 7. Vent Mode |
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 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. 5V (Vcc) 7. Vent Mode |
Check the voltage between terminals 4 and 5.
Door position | Voltage (4-5) | 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.
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.
