DTC Description: Notes
WARNING: This page is about a different car, the 2017 Hyundai Elantra. However, it is still accessible from the selected car via links, so may be relevant.
The LDWS ECU checks if each component in the ECU works out well. As a result of that, if the LDWS ECU detects abnormal operation in the ECU hardware, the LDWS ECU sets this DTC and makes a warning lamp turn on.
