Diagnosis with Diagnostic Tool
1.
In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system.
The diagnostic system 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 'CLU' to search the current state of the input/output data.
CLU Variant Coding
As we have more options (ESC, TPMS, SCC, etc.) in the car, the dashboard now have more information to display depending on the chosen options.
For this reason, we need to learn which options the current vehicle when we replace the dashboard.
To address this issue, a course of learning based on the option required for the vehicle when replacing the dashboard should be carried out.
This is called Variant Coding.
1.
Connect the cable of diagnostic tool to the data link connector in driver side crash pad lower panel.
2.
Select the 'S/W Management' and 'Car model'.
3.
Select the 'Cluster Module' and 'CLU Variant Coding'.
Variant Coding (BackUP & Input)
  
•
If the dashboard is newly replaced, it is necessary to back up the relevant information before replacing the dashboard to see what options are installed in the existing vehicle. And enter the existing dashboard information after replacing the dashboard, so make sure to perform variant coding.
1.
Back up the variable coding value before replacing the cluster.
2.
Connect the cable of diagnostic tool to the data link connector in driver side crash pad lower panel.
3.
Select the 'S/W Management' and 'Car model'.
4.
Select the 'Variant coding (Backup & Input).
5.
After checking purpose and enable condition, press the ‘OK’ button.
6.
Press the ‘OK’ button.
7.
Select ‘BackUP’ to back up the variable coding value before replacing the cluster.
8.
When the ‘Backup’ operation is completed, press the ‘OK’ button.
9.
Replacement the new instrument cluster.
(Refer to Body Electrical System - "Instrument Cluster")
  
•
If the variant code is not automatically entered, enter it manually.
10.
Connect the cable of diagnostic tool to the data link connector in driver side crash pad lower panel.
11.
Select the 'S/W Management' and 'Car model'.
12.
Select the 'Variant coding (Backup & Input).
13.
After checking purpose and enable condition, press the ‘OK’ button.

14.
Press the ‘OK’ button.
15.
Select ‘Input’ to input the coding values.
16.
When the ‘Input’ operation is completed, press the ‘OK’ button.
