This is DTC which is related with communication error between DDM and other units.

Control Units: BCM (Body Control Module), DDM (Drive Door Module), ADM (Assist Door Module), PSM (Power Seat Module), SJB (Smart Junction Box), SMK (Smart Key Module).

Case1: After short between CAN Low Line and High Line, short to ground together.

Case2: After short between CAN Low Line and High Line, short to power together.

This code is occurred when It is not possible to transmit data by CAN Line in those way of Software and Hardware. But, It is possible to receive data by CAN Line.

This code reports BUS OFF status when data transmit error count number is over 255. The purpose is to verify the status of CAN controller and CAN communication line when error is detected.

According to operation condition, some of module which are connected to CAN line may not detect B160300.

Also, B160200 coincides with B160300 at all times.
