(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 Ambient Temperature Sensor can be checked.

Replacement

1.	Disconnect the negative (-) battery terminal.

2.	Remove the front bumper. (Refer to Body - "Front Bumper Cover")

3.	Disconnect the connector (A) and then remove the ambient temperature sensor (B).

4.	To install, reverse the removal procedure.
