Kia Picanto (JA) 2017-2026 Service & Repair Manual / Heating,Ventilation, Air Conditioning / Heater / Mode Control Actuator

Components and components location

Component Location

1. Mode Control Actuator

Description and operation

Description

The mode control actuator is located at the heater unit.

It adjusts position of mode door by operating mode control actuator based on signal of A/C control unit. Pressing mode select switch makes the mode control actuator shift in order of vent→ B/L → floor → mix.

Repair procedures

Inspection

1.	Ignition "OFF”

2.	Disconnect the connector of mode control actuator.

3.	3. 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. Sensor ground
6. Feedback signal
7. Sesonr (+5V)

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 High voltage :4.9V or more
Defrost	4.55 ± 0.15V	Low voltage :0.1V or less 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 main crash pad assembly. (Refer to Body - "Main Crash Pad Assembly")

3.	Disconnect the connector (A) and then remove the mode control actuator (B) after loosening the mounting screws

4.	Install in the reverse order of removal.
