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.

B2804-00 is set when P-CAN Communication is normal, but CGW* cannot receive P-CAN message from DATC* for 10sec because there is Faulty Power Supply to DATC*, or Open/Poor Connection in High line/Low line of DATC* Branch Circuit of P-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.
