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.
The purpose of this logic is to prevent a vehicle from leaving the assembly plant or service station without a VIN in its EPROM memory. If the VIN writing is not programmed or incompatible, the ECM determines that a fault exists and a DTC is stored. And the MIL (Malfunction Indication Lamp) turns ON.
