3.Remove the keyless antenna cable and IPM(Instrument Panel Module)(A) after loosening 3 nuts and disconnecting
5 connectors.
4.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.
Slide > recline > front height > rear height > adjust pedal
b. Memory preset recall is conducted in the following order, and delay time for each motor is as follows.
T1 : Manimum 0.1 sec.
Continuous cooperation TIMER value for each motor
Slide: 15 sec., recline: 30 sec., front height: 5 sec., rear height: 8 sec., adjust pedal: 10 sec.
c. Control when turning to the opposite direction
When motor has to be run in a reverse direction during Easy access function or preset recall operation, stop the
operation immediately, wait for 100ms and then try operation to the reverse direction.
d. If the difference between position and the current one is below specified value, motor will not run even though
preset recall data is received.
Slide, recline, front height, rear height : 6PULSE
Adjust pedal: 3LSB(about 0.06V)
e. Operation will stop upon reaching Motor's target point when conducting Easy access function or preset recall
operation.
EASY ACCESS FUNCTION OPERATION (SLIDE MOTOR ONLY)
1.Easy access function operation is allowed only when auto switch is on, and the operation will be halted if auto
switch changes from on to off.
2. If a key is removed and CAN BUS data transmitted from IPM changes from "on" to "off", the seat slide will move
50mm backward based on the IGN off point. If a key off position is farther back than 50mm against the IGN off
point, get - off gearing will not be conducted. If slide rear limit becomes off in the middle of backward operation,
retreat control will be halted.
3. The following conditions will be identified and processed by IMS, and if any one of the following conditions is met,
Easy access function operation will be prevented or halted.
a. When "P" position switch is not on.
b. When Vehicle Speed in CAN BUS data transmitted from cluster is "3km/h" or faster.
c. When seat and pedal is under manual switch operation.
d. When auto switch is off.
4. When control is halted in the middle of backward operation, the remaining operation will not be completed, and
when returning, it will return just as much as it retreated.
5. It will move to IGN off point in case of Get- on gearing by key in despite manual switch input during or after
backward operation.
6. After the key is removed, on the condition of SLEEP state, Easy access function operation will be conducted after
150ms if the key is inserted when auto switch is turned ON(OFF) from Off(ON).
MEMORY STORAGE OPERATION BY KEYLESS
1.If "ID1" or "ID2" is received during keyless lock operation, record seat and pedal position in keyless code. (there is
no buzzer output during memory storage operation by keyless)
2. Memory storage operation is allowed for a single ID after a change of IG from "on" →"off".
3. Any one of the following conditions will prevent keyless Memory storage operation.
a. When "P" position switch is not on.
b. When Vehicle Speed in CAN BUS data transmitted from CLUSTER is "3km/h" or faster.
c. When seat and pedal is manipulated by CAN BUS and manual switch.
d. When IG transmitted from IPM is other than off.
PRESET RECALL OPERATION BY KEYLESS
1.When IG is off (CAN BUS data IG transmitted from IPM is "off") and a key is removed (CAN BUS data Key
Reminder Switch transmitted from IPM is "off"), and if "ID1" or "ID2" is received during keyless unlock operation, it
automatically adjusts seat and pedal positions as memorized in keyless code (there is no buzzer output during
preset recall operation by keyless). However, seat slide adjustment position is determined as follows, depending on
Auto switch.
a. When auto switch is on ("IMS Auto Switch" is "on") , the position is automatically adjusted to 50 mm farther
back than target position, and if a key is inserted ("Key Reminder Switch" changes from "off" to "on"), it
conducts Get- on gearing operation to a target preset recall position.
b. If auto switch is off ("IMS Auto Switch" is "off"), it moves to the target memory play position.
2. Any one of the following conditions will prevent preset recall operation.
a. When "P" position switch is not on.
b. When Vehicle Speed in CAN BUS data transmitted from cluster is "3km/h" or faster.
c. When seat and pedal is manipulated by CAN BUS and manual switch.
d. When IG Switch transmitted from IPM is other than off.
e. When a key is inserted.
3. Playing will be halted during preset recall operation if any of the following conditions is met.
a. When "P" position switch is not on.
b. When vehicle speed in CAN BUS data transmitted from cluster is "3km/h" or faster.
c. When seat and pedal is manipulated by CAN BUS and manual switch.
SETTING LIMIT
1.A limit switch is installed to prevent the seat from traveling beyond the maximum forward/reward positions.
2. No limit switch is installed for the recline, height, or pedal adjustments. Arbitrary limit positions are used for these
functions.
DETECTING ERRORS FOR SEAT
Take countermeasure against error if the following conditions occur during manual switch operation.
a. Error when pulse is not fed.
