Inspection (With KDS/GDS)

[BCM Type Only]

In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system (KDS/GDS).

The diagnostic system(KDS/GDS) 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.	Select the 'Car model' and the 'Body Control Module (BCM)' 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.
