Hyundai Kona (OS) 2018-2021 Service Manual / Heating, Ventilation and Air Conditioning / Blower / Intake Actuator Repair procedures

Inspection

1.	Turn the ignition switch OFF.

2.	Disconnect the intake actuator connector.

Verify that the intake actuator operates to the fresh position when connecting 12V to terminal 3 and grounding terminal 4.

Verify that the intake actuator operates to the recirculation position when connected in reverse.

1. -
2. -
3. Fresh air
4. Recirculated air

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

4.	Connect the intake actuator connector.

5.	Turn the ignition switch ON.

Check the voltage between terminal 6 and 5.

•	It will feedback the current position of the actuator to controls.

Specification

Door position	Voltage (V)	Error detecting
Fresh air	0.5 ± 0.15	Low voltage : 0.1V or less
Recirculated air	4.5 ± 0.15	High voltage : 4.9V or more

7.	If the intake actuator does not operate well, substitute with a known-good intake actuator and check for proper operation.

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

Diagnosis With GDS

The heating, ventilation and air conditioning can be quickly diagnosed failed parts with vehicle diagnostic system (GDS).

※ The diagnostic system (GDS) provides the following information.

(1) Self diagnosis : Checking the failure code (DTC) and display.

(2) Current data : Checking the system input/output data state.

(3) Actuation test : Checking the system operation condition.

(4) Additional function : Other controlling such as he system option and zero point adjustment.

2.	Select the 'Car model' and the system to be checked in order to check the vehicle with the tester.

3.	Select the 'Current data' menu to search the current state of the input / output data. The input / output data for the sensors corresponding to the Intake Actuator can be checked.

4.	To perform compulsory operation on Intake Actuator input factors, select "ACTUATION TEST".

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 and then remove the intake actuator (A) after loosening the mounting screws.

4.	To install, reverse the removal procedure.
