4.
Connect the temperature control actuator connector.
5.
Turn the ignition switch ON.
6.
Check the voltage between terminal 5 and 6.
7.
If the measured voltage is not within specification, check the operation by replacing the existing temperature control actuator with a new genuine part. After that, determine whether replacement of the temperature control actuator is required or not.
Diagnosis With GDS
1.
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 Temperature Control Actuator can be checked.

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