1.CLU
2.MDPS
Cluster memorizes what kinds of control unit are installed on through the CAN-BUS. Vehicle Optional information is memorized in cluster by EOL Coding procedure in the End of Line. DTC will be set if the optional information is different when comparied between memorized optional information from CAN-BUS and optional information sent by EOL. In the assembly line, EOL communication will be finished in case that DTC is not set during DTC searching.
In service field, it is necessary to set cluster by using variant coding procedure with GDS in order to syncronize the opitional parts on the vehicle after replacing cluster.
This DTC is set when variant coding is incorrectly performed as if MDPS option is installed on the vehicle even though real vehicle has not MDPS on the CAN BUS.

Detecting Condition
Possible Cause
DTC Strategy
Check CAN Communication
Check option information and performance
Perform cluster coding performance
Check EPB,TPMS,ESC,MDPS,ABS,AIRBAG CAN line and Module.
Check Cluster
Enable Conditions
Failed cluster coding performance
Threshold Value
MDPS CAN error
End of Line has MDPS option information even though MDPS has not been detected on the CAN BUS
Diagnostic Time
Mismatched conding code with real vehicle
DTC Erasing Time
In case of correctly performed coding procedure or erased DTC after solved problem
