Inspection (with GDS)

The body electrocal system 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 "Body Control Module (BCM)" to check the multi function switch.

4.	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 multi function switch can be checked.
