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.
In case that RF Module in IPM is not matached with local frequency,such as RF module for North America but IPM for Korea, IPM sets DTC.
Item | Detecting Condition | Possible Cause |
DTC Strategy |
•
Check matching between RKE frequency and Module frequency |
•
Check wrong IPM |
Enable Conditions |
•
IG ON | |
Threshold Value |
•
Detected that RF Module frequency is unmatching with local frequency | |
Diagnostic Time |
•
Immediately | |
DTC Erasing Time |
•
DTC is erased immediately after trouble fixed (In case of the past error, perform DTC erasing procedure.) |
