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 3 and
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. Sensor (+5V)
5. Check the voltage between terminals 6 and 5.
Door position
Voltage (6-5)
Error detecting
Vent
0.45 ± 0.15V
Low voltage : 0.1V or less
Bi-Level
1.4 ± 0.15V
Floor
2.45 ± 0.15V
Mix
3.5 ± 0.15V
Defrost
4.55 ± 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 side cover (A).
