Monitor DTC Status

Plug GDS to Data Link Connector (DLC).
Turn "ON" the ignition switch.
Select "Diagnostic Trouble Codes (DTC)," and click "DTC Status" to check DTC information.
Read the "DTC State" parameter.
Is the DTC State "Present?"
"PRESENT"
- Diagnose the EMS ECU system using the GDS and see if there is a DTC related to the vehicle speed. If so, repair it first and then see if the DTC is cleared from the BSD module. Then, go to next procedure.
"HISTORY"
- The memory was not cleared after repair. Clear the DTC and go to "VERIFICATION OF VEHICLE REPAIR ".
