Diagnosis with GDS
1.
The body electrocal 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 he 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 model and "BCM".
3.
Select Variant coding mode to perform.

4.
If the trouble codes occurred when performing variant coding, try the CLU variant coding again after checking the installation status of CLU system.
