- Description Cluster 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. - Removal

1.Disconnect the negative (-) battery terminal.

2.Remove the cluster fascia panel.(Refer to Body - "Cluster Fascia Panel")

3.Remove the cluster (A) from the housing after loosening the mounting screws.

4.Disconnect the cluster connecter (A) and then remove the cluster (B).

- Installation

1.Connect the cluster connector.

2.Install the cluster assembly.

3.Install the cluster facia panel.

4.Connect the negative (-) battery terminal.

- Inspection

1.Check point (Warning indicator)cator)

Fault conditions and normal operating conditions, refer to the owner's manual.

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'.
