(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.	Select the 'Car model' and the steering wheel remote control system (SWRC) to be checked in order to check the vehicle with the tester.
