Easy Access Function

(user option - default: Operating easy access function)

  1. If Signal "BCM KEY IN" transmitted from BCM and signal "LOCAL KEY IN" in case that key is removed are changed from "LOW" (KEY IN) ->"HIGH" (KEY OFF), SEAT SLIDE is moved 75mm backward from KEY OUT position.
  2. Signal "BCM KEY IN" transmitted from BCM or signal "LOCAL KEY IN" is changed from "HIGH" (KEY OFF) ->"LOW" (KEY IN) by inserting KEY, it is moved to KEY OUT position.
  3. Prohibiting and Stopping easy access operation. The following requirements are determined and controlled by IMS. If one of the following conditions is met during anti-operation or operation process, it is stopped.
    1. "P" Position switch is not ON

      (If "P" Position switch is OFF during operating, the operation is completed.)

    2. Vehicle data "SPEED" transmitted from BCM is LOW (More than 3 km/h)
    3. MANUAL switch of SEAT is in operation
    4. Reproduction command is received during easy access operation
    5. "AUTO_SET" DATA transmitted from IMS switch has "OFF" value.

      (If "AUTO_SET" is changed during operating, the operation is completed.)

    6. SET message transmitted from IMS switch is "1" during easy access operation
  4. If control is stopped during moving backward, the backward action is paused without moving further. When returning, it moves just as much the distance as it previously moved backwards.
  5. MANUAL switch Input is operated during or after moving backward, it will move to KEY OUT position on easy access operated by KEY IN.
  6. Condition to Restore Memory of riding position in a vehicle
    1. MANUAL switch is operated in the level above Key IN
    2. Reproducing memory is in operation

LIMIT Setting

  1. LIMIT position is randomly set as following since there is no SLIDE, RECLINE, rear right height, and Front rear height LIMIT switch.
    1. Control is immediately stopped, and the location in front of 6 pulse is set Driving LIMIT position, if more than 6 PULSE is not generated for 2 seconds during initial operation by MANUAL switch or by easy access function after inserting battery. (LIMIT position in reverse direction is the same as above.)

      However, LIMIT position for Front rear height and rear right height is set if more than 6 PULSE is not generated for a second.

    2. If virtual LIMIT is set, MEMORY Reproduction is not operated off the LIMIT boundary for preventing motor damage by mechanical LOCK
    3. If PULSE is correctly input away from the LIMIT boundary by MANUAL operation or by Easy access function with the previously set LIMIT applied, LIMIT position is renewed

Detecting and Controlling ERROR

  1. Detecting seat ERROR

    ERROR is controlled if the following situation occurs during easy access operation, reproduction process and operating MANUAL switch of each motor.

    1. ERROR resulted from PULSE is not input

      Related motor output is stopped if ERROR is detected during reproduction and easy access operation

      Related motor output is stopped, if ERROR is found in MANUAL operation.

    2. Sensor Vcc of Seat is detected as much as 40ms from less than 1V. => Return if Sensor Vcc of Seat is over 7V.

      If SEAT Sensor Vcc ERROR is detected during reproduction and easy access operation, all operating SEAT motor is stopped.

      (BUZZER output is not operated.)

  2. ERROR Control

    If ERROR is detected as shown above, it is considered to be caused by broken HARNESS or Sensor malfunctioning, and is controlled as following.

    1. BUZZER output is operated during receiving storage and reproduction command regardless of ERROR occurrence
    2. Paused easy access operation and memory reproduction is available to be re-activated from operating MEMORY command after motor malfunctioning is repaired, and it is as following.

      (When SLIDE motor is repaired from Sensor ERROR, Easy access function is available)

      SEAT: 6 PULSE is correctly input from ERROR causing motor position Sensor by operating MANUAL switch with in 2 seconds (SLIDE, RECLINE)/1 second (Front rear height, Rear right height).

Determining Seat Position

Seat position is relatively determined rather than by absolute position.
