General Description

IMS(Integrated Memory System) is a system which can memorize the position of power seat(PSM), tilt/telescope handle(SCM), side mirror(DDM/ADM) by position sensor and restores them to a previous position. (Memory function is not allowed during driving for safety reason)

DTC Description

PSM sets this code when amount of change of the Recline motor position sensor is less than 12edge (6pulse) for 2sec. This means that Recline motor/sensor stuck due to open or short in circuit or external cause (compulsive restriction)
