Borrego 2WD V6-3.8L (2009)
Steering Column Control Module: Description and Operation
Operation
1. Manual operation
manual SW manipulation enables steering operation by the input of manual SW Manual operation is always possible for tilt , tele.
motor is not allowed to run under Limit SW off during manual SW operation.
2. Memory storage operation
(1) Memory permission operation
If CAN BUS data " IMS_Mem Cmd" transmitted from is SET, it enters Memory permission mode.
(2) Memory operation
If CAN BUS data(IMS_Mem Cmd) transmitted from DDM is MEMORY1 or MEMORY2.
TILT& TELE Unit will memorize the current steering positions.
(3) Memory conditions
Failure to meet any one of the following conditions will trigger ban or cancellation of Memory permission. (DDM determines if the following
conditions are met or not, and only if all four conditions are met, it transmits Memory permission order ("IMS_Mem Cmd": "SET ") and
Memory order (" IMS_MemCmd":"Memory1" or "Memory2").
A. CAN BUS data "Ignition Sw Sts" transmitted from IPM is "RUN".
B. CAN BUS data "Inhibit Sw Sts" transmitted from CLU is "P".
C. CAN BUS data "Vehicle Speed" transmitted from CLU is "3km/h" or below.
D. Below 5 sec. After Memory SW off-> on.
(4) Memory set does not have a limit in terms of the number of inputs.
(Storage by Memory SW manipulation once is limited to once)
(5) When battery is removed. Memory is clear
3. Memory play operation
(1) Play operation
If CAN BUS data (IMS_Mem Cmd) transmitted from DDM is "RETURN 1"or "RETURN 2".
TILT & TELE unit automatically put steering column back to a remembered position
(2) Halt conditions
DDM will transmit CAN BUS data to generate Memory play order only in case that two conditions of a, b ( in the following 5) items are met
and one condition of 3,4 items is met.
A. CAN BUS data "Inhibit Sw Sts" transmitted from CLU is "P".
B. CAN BUS data "Vehicle Speed" transmitted from CLU is "3km/h" or below.
C. In case that the MEM1/MEM2 SW of IMS SW is ON, if driver door open or in 30 seconds after driver door close.
D. CAN BUS data "Ignition Sw Sts"transmitted from IPM is "RUN".
E. No manual SW manipulation for TILT & TELE t (determined by TILT&TELE )
(3) Halt conditions (determined by TILT&TELE)
Failure to meet any one of the following during play operation will halt the operation.
A. CAN BUS data "Inhibit Sw Sts" transmitted from CLU is "P".
B. CAN BUS data "Vehicle Speed" transmitted from CLU is "3km/h" or below.
C. The limit sw of moving direction. is ON during operation.
D. In case that target position of motor (±6 EDGE) is not arrived.
E. No manual SW manipulation for steering column.
(4) Others
A. If pulse difference between previously memorized position and current position is beyond 4 pulse.Do not operate motor.
B. If engine is started (if "Ignition Sw Sts" is "START") during Play operation, halt Play operation, and resume it toward target position
100ms after "Ignition Sw Sts" is returned to "RUN". However, if the START state lasts over 30 sec. it will not resume even after returning
to RUN.
C. If an error occurs during manual operation of TILT & TELE, do not delete Memory.
(5) Operation control
A. Prioritization of operations
Motor starting is delayed for 100ms respectively in case of auto control to prevent rush current from overlap when motors are running, and
it follows the following order.
TILT > TELE
B. Memory play is conducted in the following order, and delay time for each motor is as follows.
Continuous cooperation TIMER value for each motor
TILT : 4 ± 1sec, TELE : 5 ± 1sec
C. Control when turning to the opposite direction When motor has to be run in a reverse direction during Get-on/off gearing or play operation,
stop the operation immediately, wait for 100ms and then try operation to the reverse direction.
D. If the difference between memorized position and the current one is below specified value, motor will not run even though play data is
received.
* TILT, TELE : 8EDGE(4PULSE)
E. Operation will stop upon reaching Motor's target point when conducting Get-on/off gearing or play operation.
4. Get-on/off gearing operation
(1) Get-on/off gearing operation is allowed only when CAN DATA (IMS_Auto Sw) transmitted from DDM is ON.
