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)

*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.

DTC Description

IPM sets DTC when EEPRM of Micom in IPM is read / write error.

DTC Detecting Condition

Item	Detecting Condition	Possible Cause
DTC Strategy	• Check EEPROM read / write status	• Faulty IPM
Enable Conditions	• IG ON
Threshold Value	• EEPROM read / write error
Diagnostic Time	• Immediately
DTC Erasing Time	• DTC is erased immediately after trouble fixed (In case of the past error, perform DTC erasing procedure.)
