Driver Door Module
B1671 DDM and IMS SERIAL COMMUNICATION ERROR - General Information

Component Location





General Description

All 13 units which consists of the Body Electrical Control System are linked by CAN* line.
They are IPM(Inter Panel Module), FAM(Front Area Module), PDM(Power Distribution Module), DDM(Drive Door Module), ADM(Assist Door Module), ECW(Electronic Control Wiper), CLU(Cluster), MFSW(Multi Function Switch), PSM(Power Seat Module), SCM(Steering Control Module), PTM(Power Trunk Lid Module), FBWS(Front Back Warning System), DATC(Dual Auto Temperature Control Module).
DDM is linked with IMS(Integrated Memory System) SW by Serial communication line. Therefore, It is possible to control Drive Seat by DDM.
* 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. (This is less expensive.)






DTC Description

This code is outputted when the serial communication protocol is broken between DDM and IMS by open, short or noise.
