Borrego 4WD V6-3.8L (2009)
Memory Positioning Module: Description and Operation
Description
system outline
An optimal seat position set by a driver can be memorized in Power seat unit by IMS SW, which enables restoration of seat position set by the driver
despite
Playing of this function during drive is banned for safety reasons, and it has emergency stop function of restoration and gearing operation as well
Input Specification
1. IGN2
IGN is judged by local SW "IGN2"and CAN data "Ignition sw Sts"
2. Seat manual SW: Seat Input
(1) Slide FR / RR manual SW
SW that moves slide motor of a seat forward or backward
(2) Recline FR / RR SW
SW that moves recline motor of a seat forward or backward
(3) FR height up / down manual SW
SW that moves front height motor of a seat upward or downward
(4) RR height up / down manual SW
SW that moves rear height motor of a seat upward or downward
3. Seat position sensor (pulse signal)
A. A sensor to sense the movement of slide, recline, FR height and RR height motor.
4. "P" position SW
This SW detects parking state of transmission.
Get-on/off gearing and memory storage are not allowed in positions other than "P". (AT only)
("P" position SW is used because INH "P" detection is not possible when IGN is off)
"P" Position SW is used in case that CAN is time out
5. IMS SW: It Is transmitted to IMS with CAN communication after DDM input
(1) SET SW
SW that sets the position of seat by a driver at memory allowed state
(2) MEM 1, MEM 2 SW
SW that memorizes and plays the position of seat set by a driver
6. CAN communication line (CAN Hi, CAN Low)
IMS communicates IPM, FAM, DDM, ADM, RAM, CLU and SCM through CAN BUS
(At the speed of 50kbps)
7. Limit SW
SW that prevents restriction of seat and its contact point is normal close type.
Functional specification
1. Output time
Buzzer output: 0.1 sec. On, 0.4 sec. off
2. Output condition
*When it is allowed Memory mode (memory SW on): once
*When Memory storage mode is completed (Position SW on): twice
*When Memory mode is played (Position SW on): once
*When Easy Access operation is set (IMS Auto Sw ON): twice
*When Easy Access operation is canceled (IMS Auto Sw OFF) : once
*When error occurs due to sensor failure: 10 times
The conduct of input signal chattering
1. 40ms objects : input SW
* Slide, recline, FR height, RR height manual SW
* "P" position SW
* Slide FR/RR limit SW
* Recline FR/RR limit SW
2. IGN is judged by local SW "IGN2" and CAN data "Ignition Sw Sts"
Function
Manual operation
1. Manual operation of seat
Seat manual SW manipulation enables seat operation by the input of manual SW.
Manual operation is always possible for slide, recline, front height and rear height even though ECU B+ is off as long as IGN2 is on.
