DTC Description

WARNING: This page is about a different car, the 2021 Hyundai Kona. However, it is still accessible from the selected car via links, so may be relevant.

C1818-00 is set when C-CAN Communication is normal, but CGW* cannot receive C-CAN message from LCA* for 10sec because there is Faulty Power Supply to LCA*, or Open/Poor Connection in High Line / Low Line of LCA* Branch Circuit of C-CAN network.

If the DTC still appears even if the problem is corrected and the system operates normally, perform "Vehicle S/W Management"  → "Erase Network Configuration", and erase the DTC.
