Integrated Memory System (IMS) / Description And Operation

Description

The optimum seat position set by the driver is memorized in the power seat unit by IMS switch control to be recalled by using the IMS switch even if the seat position has been changed.

It is equipped with safety functions such as prohibition of recalling and emergency stopping of linked motion while driving.

Manual Operation

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)

Memory function

Can memorize and recall data for up to two persons with IMS switch.

1. Memorized operations of seat and outside rearview mirror positions are operated by IMS switch via CAN (IMS → DDM) when the optimum seat position is set by the driver.
2. Recall by the CAN data received from IMS switch control.

Linked motion for getting on/off

1. The driver's seat moves backward when the driver get off from the vehicle.
2. Condition for operating getting on : When the electric power is in ACC, When Engine OFF, if the driver close the driver side door with carring samrt key (When ON at the User Setting Mode)
3. Condition for operating getting off : When the electric power off and open the driver door.

Operation

Recall operation

1. The buzzer will operate once and automatically be adjusted to the memorized position when the CAN data from IMS is received.
2. Unsaved recall signals will not be performed.
3. If another recall signal is received during recall operation, the last received recall signal prevails.
4. If recall signal is received by pressing switch 1 or 2 during recall operation, the seat will stop recall operation.
5. If memory signal is received by pressing SET button during recall operation, the seat will stop the recall operation.

Warning

Press the SET button once more to store the position of stop.

6. Automatically stop at the virtual limit position during recall operation.
7. If the difference between memorized position and current position is less than 4 pulses, motor will not be operated.

Conditions for prohibiting recall operation

Recall operation is prohibited and recall operation is stopped if any of the following conditions is met.

1. IGN2 OFF (except within 30 seconds of opening or closing door)
2. Over 3 km/h of vehicle speed
3. In case of manual switch manipulation
4. Operation time chart

Decision on the operation priority

1. The motor operation shall be delayed for 100+-10 milliseconds to prevent the overlapping of inrush circuit during motor start. In this case, the priority is as follows.

   Slide > Backrest adjustment >Front height adjustment >Rear height adjustment Operation time chart

Operation linked with getting on/getting off

1. Return operations backwards when getting off and forward when getting on (slide type only)
2. It is available when the automatic SET message transmitted from the driver seat power window switch (DDM) is ON.

Warning

Applied only to driver's settings menu (USM) is on.

3. Starting of operation when the electric power off and open the driver door.
4. Move to the target potision of ACC ON.
5. Condition for prohibiting operation

• Over 1.8 MPH (3km/h) of vehicle speed
• In case of power seat manual control switch manipulation
• On receiving recall command during operation for getting on
• Driver Settings Manu (USM) is Off
