Cluster Variant Coding
As we have more options (ESC, MDPS etc.) in the car, the dashboard now has more information to display depending on the chosen options.
For this reason, we need to learn which options the vehicle has when replacing 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.

4.
User Setting Mode (USM)
Setting can be changed by using switchs (Menu, UP, Down and OK button). There are many items (for example, In/Out Seat Synchronization, In/Out Steering Wheel Synchronization, Auto Door Lock, Auto Door Lock Deactivate, Head Lamp Escort, Welcome Light, Welcome Sound, One Touch Turn Signal, Average Fuel Consumption Auto Reset, Brightness, and Content Setup) that can be set and customized. The signal flow during setting is as follows.
(1)
UMS settings are set, they are transmitted to BCM.
(2)
BCM transmits the settings via B-CAN to the relevant modules.
(3)
The module completes setting and transmits the modified setting to BCM.
(4)
BCM transmits the final settings via C-CAN to the cluster.
  
The cluster communicates directly with C-CAN units.

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.
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'.
