Repair procedures

Removal

When prying with a flat-tip screwdriver or use a prying trim tool, wrap it with protective tape, and apply protective tape around the related parts, to prevent damage.

1.	Disconnect the negative battery terminal.

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

3.	Remove the instrument cluster (A) by loosening the mounting screws.

4.	Disconnect the instrument cluster connectors (A).

Installation

1.	Install in the reverse of the removal.

2.	After replacing the cluster with a new one, the "Variant Coding" procedure must be performed.

Diagnosis with KDS

In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system (KDS).

The diagnostic system (KDS) provides the following information.

(1)	Self diagnosis : Checking failure and code number (DTC)

(2)	Current data : Checking the system input/output data state

(3)	Actuation test : Checking the system operation condition

(4)	Additional function : Controlling other features including system option setting and zero point adjustment

2.	Select the 'Car model' and the 'Cluster Module (CLU)' to be checked in order to check the vehicle with the tester

3.	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.

4.	To forcibly actuate the input value of the module to be checked, select option 'Actuation Test'
