Monitor GDS Data
- Connect GDS to Data Link Connector (DLC).
- Turn the ignition ON and start the engine.
- Check if there are any DTCs related to the SCC system. If there is a DTC related to the system, repair it first and diagnose the LDWS/LKAS.
- Does the same DTC return?
YES
- Replace the SCC with usable ones and check for proper operation. If the problem is corrected, replace the SCC and go to "VERIFICATION OF VEHICLE REPAIR ".
NO
- Fault is intermittent, caused by poor contact of connector or wire harness. Or, the LDWS/LKAS memory was not cleared after repair. Thoroughly check connectors for looseness, poor contact, bending, corrosion, deterioration, or damage.
- Repair or replace relevant component(s) as necessary and then go to "VERIFICATION OF VEHICLE REPAIR ".
