MEMORY STORING AND KEYFOB INTERLOCK STORING

Store the 2 driving positions and shifts to the stored driving position with the memory switch.

Keyfob interlock function is set simultaneously with setting driving position memory. It can set driving posi-
tion to memory position.
NOTE:

If another keyfob interlock function setting is performed by same key, newly registered setting is valid.

If new memory string is performed to memory switch that already set keyfob interlock function, keyfob
interlock function setting is reset.

If key does not set previously, keyfob interlock function cannot set.

KEYFOB INTERLOCK OPERATION

Perform memory operation, exiting operation and entry operation by pressing keyfob unlock button.
NOTE:

If ignition switch turns ON in the middle of memory operation, the system does not perform exiting opera-
tion after memory operation.

If ignition switch turns ON in the middle of exiting operation, entry operation starts at that time.
FAIL- SAFE MODE
When any manual and automatic operations are not performed, if any motor operations of seats are detected
for approx. 0.1 sec or more, status is judged “Output malfunction”. Motor operation will be suspended auto-
matically, and all automatic operations will be ineffective (in this case, the motor will not operate manually).
CANCEL OF FAIL-SAFE MODE

The mode is cancelled when the selector lever is shifted to P position from any other position.

HEATED SEATPFP:87335
System Description BIS0013C

Each seat cushion has seat heater unit.

Front heated seat is composed the following
–Heated seat relay
–Front heated seat switch
–Seat heater unit

Rear heated seat is composed the following
–Heated seat relay
–Heated seat switch
–Seat heater unit
–Heated seat control unit

Heated seat system has two operation pattern, LOW and HIGH.
NOTE:

When handling seat, be extremely careful not to scratch seat heater unit

To replace heating unit, seat trim and pad should be separated.

Do not use any organic solvent, such as thinner, benzene, alcohol, etc. to clean trims.
FRONT HEATED SEAT
When ignition switch is ON or START, heated seat relay activates.
Then power is supplied

through 10A fuse [No. 8, located in fuse block (J/B)]

through heated seat relay terminals 3 and 5

to front heated seat switch (driver side and passenger side) terminal 1.
Driver Side
LOW FUNCTION
When front heated seat switch (driver side) is in LOW position, power is supplied

through front heated seat switch (driver side) terminal 2

to seat heater (driver side) terminals 53.
And, ground is supplied

to seat heater terminal 52

through grounds B16 and B17.
Then seat heater (driver side) LOW function is activated.
At this time ground is supplied

to front heated seat switch (driver side) terminal 4

through grounds M71 and M72.
Then indicator illuminates in front heated seat switch (driver side).
HIGH FUNCTION
When front heated seat switch (driver side) is in HIGH position, power is supplied

through front heated seat switch (driver side) terminal 3

to seat heater (driver side) terminals 54.
And, ground is supplied

to seat heater terminal 52

through grounds B16 and B17.
