Cluster Variant Coding
As we have more options (ESC, TPMS, 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.

Diagnosis with GDS
1.
The body electrical 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)
Actuator test : Checking the system operation condition
(4)
Additional function : Other controlling such as the 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 "Cluster Module (CLU)".
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 cluster module (CLU) can be checked.

5.
To check the input value of cluster illumination, select option "Actuation Test".
CLU Variant Coding
After replacing the cluster with a new one, must be performed the "Variant Coding" procedure.
1.
Connect the cable of GDS to the data link connector in driver side crash pad lower panel, turn the power on GDS.
2.
Select the "Body Control Module (BCM)" to check the"'Cluster Module (CLU)".
3.
Select variant coding mode to perform.
