Diagnosis with Diagnostic tool
1. |
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. |
Connect the cable of Diagnostic tool to the data link connector in driver
side crash pad lower panel, and turn on the Diagnostic tool.
|
3. |
If diagnose the vehicle by Diagnostic tool, select "DTC Analysis" and
"Vehicle".

|
4. |
If check current status, select the "Data Analysis" .

|
5. |
Select "BCW", if you want to check current data of BCW system.
