How to Troubleshoot DTCs
Check and clear the DTCs with the HDS.
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 during the test-drive, but troubleshooting is done based on the 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 same conditions as when the DTC was originally set. Make sure the LKAS indicator does not come on.
-
LKAS system sometimes stops control because of the environment (weather, road conditions, driving conditions, etc.). A DTC may be stored in these cases.
DTCs that may be stored even when the system is normal:
