The other information about the cluster

(1)

USM (User Setting Mode)

A.

USM is set using the steering wheel remote control button.

B.

IMS seat, IMS steering, auto door lock/unlock, head lamp escort, welcome light, welcome sound and triple turn signal lamp are controled.

(2)

USM setting procedure

A.

Send the USM value to the BCM

B.

BCM send the setting value to the each module through CAN.

C.

Each modules send the setting complete value to BCM.

D.

BCM send the final setting value to cluster through CAN.

Diagnosis with GDS
1.

It will be able to diagnose defects of CLU with GDS quickly. GDS can operates actuator forcefully, input/output value monitoring and self diagnosis.

2.

Select model and "BCM".

3.

Select the "Cluster Moduel" to check.

4.

Select "Input/output monitoring", if you will check current data of instrument cluster.

5.

If you will check each module data operation forcefully, select "Actuation test".

6.

To check the DTC of the each module, select "DIAGNOSTIC TROUBLE CODES".

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.
