Inspection (With Diagnostic tool)

In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system (Diagnostic tool).

The diagnostic system (Diagnostic tool) provides the following information.

(1)	Fault Code Searching : Checking failure and code number (DTC)

(2)	Data Analysis : Checking the system input/output data state

(3)	Actuation test : Checking the system operation condition

(4)	S/W Management : Controlling other features including system option setting and zero point adjustment

2.	If diagnose the vehicle by Diagnostic tool, select "DTC Analysis" and "Vehicle".

3.	If check current status, select the "Data Analysis" and "Car model".

4.	Select the 'IBU_BCM' to search the current state of the input/output data.
