General Description

IMS (Intergrated Memory System)
Seat and mirror positions set by the driver are memorized in the IMS control unit by the position sensors. Those positions can be returned to the memorized positions by the IMS control switch and keyless control even when the seat and mirror positions are changed. (This is called replay operation.)
In addition, LIN (Local Interconnect Network) communication is performed between power seat control unit and power window main switch module. For the sake of safety, replay is prohibited during driving and replay operation can be stopped immediately.






DTC Description
