General Information

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

In case that RF Module in IPM is not matched with local frequency,such as RF module for North America but IPM for Korea, IPM sets DTC.
