Kia Stinger CK: Heater / Temperature Control Actuator

Kia Stinger (CK) 2018-2023 Service Manual / Heating, Ventilation And Air Conditioning / Heater / Temperature Control Actuator

Description and operation

Description

The heater unit consists of mode control actuator and temperature control actuator.

Located in the heater unit, the temperature control actuator regulates the temperature in the following procedures.

Signal from control unit adjusts the position of the temperature door by operating the temperature switch. Then the temperature will be regulated by the hot/cold air ratio decided by the position of the temperature door.

Repair procedures

Inspection

1.	Turn the ignition switch OFF.

2.	Disconnect the temperature control actuator connector.

Verify that the temperature control actuator operates to the cool position when 12V is connected to terminal 3 and ground to terminal 7.

Verify that the temperature control actuator operates to the warm position when connected in reverse.

1. -
2. -
3. Warm position
4. Sensor ground

5. Feedback signal
6. Sensor (+ 5V)
7. Cool position

4.	Connect the temperature control actuator connector.

5.	Turn the ignition switch ON.

Check the voltage between terminals 5 and 4.

Specification

Door Position	Voltage (V)	Error Detecting
Max. cooling (Driver side)	0.3 ± 0.15V	Low voltage : 0.1V or less High voltage : 4.9V or more
Max. heating (Driver side)	4.7 ± 0.15V
Max. cooling (Passenger side)	0.3 ± 0.15V
Max. heating (Passenger side)	4.7 ± 0.15V

The current position of the actuator will be sent to the control unit.

7.	If the measured voltage is not within the specification, substitute with a verified temperature control actuator and check for proper operation.

8.	Replace the temperature control actuator if it is proved that there is a problem with it.

Replacement

[Driver side]

1.	Disconnect the negative (-) battery terminal.

2.	Remove the knee airbag. (Refer to Restraint - "Knee Airbag (KAB) Module")

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

4.	Install in the reverse order of removal.

[Passenger side]

Repair procedures Inspection 1. In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system (KDS). The diagnostic system (KDS) provides the following information. (1) Self diagnosis : Checking failure and code number (DTC) (2) Current data : Checking the system input/output data state (3) Actuation test : Checking the system operation condition (4) Additional function : Controlling other features including system option setting and zero point adjustment 2.
