Component Location





General Description

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)
* 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.






DTC Description

If FAM or RAM are missing on the CAN Line or it is impossible to communicate via CAN because of faulty IPM, FAM or RAM, IPM sets This DTC.
