How to Troubleshoot DTCs
WARNING: This page is about a different variant/trim than selected.
Check for DTCs with the HDS, then clear the DTC.
NOTE: For LKAS DTCs, refer to the DTC troubleshooting index .
Before troubleshooting, check and note these items:
- Ask the customer about the conditions when the problem occurred, and try to reproduce the same conditions for troubleshooting.
- If the symptom does not appear and the LKAS indicator does not come on while test-driving and if your troubleshooting was based on a DTC, check for poor connections or loose terminals at all connectors related to the circuit that you are troubleshooting.
- After the troubleshooting or repairs are done, clear the DTCs, and test-drive the vehicle under the same conditions as when the DTC was originally set. Make sure the LKAS indicator does not come on.
- The LKAS sometimes stops operating because of the environment (weather, road conditions, driving conditions, etc.). A code may be stored in these cases.
