Description And Operation: Description

The IMS switch control memorizes the preset seat position set by the driver. When selecting the memory preset, the power seat returns to the one of the two seat positions selected when the vehicle's seat has been moved.

It is equipped with safety functions such as prevention of memory recall and emergency stop seat movement while driving.

The main functions are as follows.

1. Manual operation: Motor control with the seat manual switch
   1. The position of the seat is changed by operating the motor when the signal is input with manual switch for the seat (Slide, recline, front tilt, rear height adjusting)
2. Memory function: Can memorize and recall data for up to two persons with IMS switch.
   1. Memorized operation of seat and outside rearview mirror position by CAN data (IMS → DDM) when the optimum seat position set by the driver is operated by IMS switch.
   2. Recall by the CAN data received from IMS switch control.
3. Linked motion for getting on/off
   1. Linked motion for getting on/off depending on the ON/OFF state of the engine
   2. Uses IMS CAN data communication
   3. Operating condition for getting on: ACC ON
   4. Operating condition for getting off: Engine OFF
4. Memorization and recalling of mirror position using memory switch
   1. System Description
      • IMS switch inputs are received at Power Seat Module (PSM).
      • On receiving IMS switch input, the PSM will send the information to DDM and ADM via CAN.
      • On receiving the information from the PSM, the DDM and the ADM will memorize and restore it.
   2. Memorization and recall are performed if the following conditions are met:
      • IGN ON
      • Gear in P (Park)
      • The vehicle speed is 0 km/h according to the information transmitted from the BCM via CAN.
   3. Mirror Position Memorization
      • Move the driver side and passenger side outside rearview mirrors to desired positions.
      • Press the SET switch from IMS switches.
      • Press switch 1 or 2 for a set period of time.
      • The mirror positions will be stored in the IMS switch 1 or 2 of the DDM and the ADM.
