This is DTC which is related with communication error between IPM and other units.
(※ Control Units : IPM(Inter Panel Module), FAM(Front Area Module), PDM(Power Distribution Module), DDM(Drive Door Module), ADM(Assist Door Module), CLU(Cluster), PSM(Power Seat Module), SCM(Steering Control Module), RAM(Rear Area Module), SMK(Smart Key)
*¹ CAN (Controller Area Network) : CAN is serial bus communication type which links not only communication system but also control units each other.
*² LIN (Local Interconnect Network) : LIN is serial communication type which is used in electrical control system.
IPM sets DTC in case of EEPRM data error.
