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 when EEPRM of Micom in IPM is read / write error.
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.)  |
