TURN SIGNAL AND HAZARD WARNING LAMPS
Revision: 2006 July 2007 FX35/FX45
through rear combination lamp control unit terminal 9
to rear combination lamp RH terminal 3,
through rear combination lamp RH terminal 4
to rear combination lamp control unit terminal 8.
And hazard switch is depressed, ground is supplied
to hazard switch terminal 2
through BCM terminal 29,
to grounds M35, M45 and M85
through hazard switch terminal 1.
BCM sends signal to the unified meter and A/C amp. through CAN communication, and turns ON turn signal
indicator lamp with combination meter.
When rear turn signal lamp (LED) does not turn ON, rear combination lamp control unit sends signal to combi-
nation meter. And then unified meter and A/C amp. ends turn LED burnout status signal to BCM through CAN
communication lines for speeding up turn signal blinking.
REMOTE CONTROL ENTRY SYSTEM OPERATION
When the remote control entry system is triggered by input from key fob, BCM output turn signal from BCM
terminals 45 and 46, interpreting it as turn signal is ON.
Connected from BCM terminals 45 and 46 to front combination lamp RH and LH terminals 4.
Turn signal lamp turns ON
through front combination lamp RH and LH terminals 8
to grounds E21, E50 and E51.
Connected form BCM terminals 45 and 46 to rear combination lamp control unit terminals 4 and 5.
Rear turn signal (LED) turns ON
through rear combination lamp control unit terminal 11
to rear combination lamp LH terminal 3,
through rear combination lamp LH terminal 4
to rear combination lamp control unit terminal 10,
through rear combination lamp control unit terminal 9
to rear combination lamp RH terminal 3,
through rear combination lamp RH terminal 4
to rear combination lamp control unit terminal 8.
BCM sends signal to the unified meter and A/C amp. through the CAN communication, and turns ON turn sig-
nal indicator lamp with combination meter.
With power and input supplied, BCM controls the flashing of hazard warning lamps when key fob is used to
activate remote control entry system.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
CAN Communication System DescriptionNKS002XE
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNKS002XF
Refer to LAN-49, "CAN System Specification Chart" .

AUTOMATIC DRIVE POSITIONERPFP:28491
System Description NIS001UO
The system automatically moves the driver seat to facilitate entry/exit to/from the vehicle. The automatic
drive positioner control unit can also store the optimum driving positions (driver seat, steering wheel posi-
tion (tilt, telescopic) and door mirror position) for 2 people. If the driver is changes, one-touch operation
allows changing to the other driving position.
The settings (ON/OFF) of the automatic sliding seat (Entry/Exiting operation) at entry/exit can be changed
as desired, using the display unit in the center of the instrument panel. The set content is transmitted by
CAN communication, from display control unit to driver seat control unit.
Using CONSULT-II, the seat slide and steering wheel amount at entry/exit setting can be changed.
MANUAL OPERATION
The driving position [seat position, steering wheel position (tilt, telescopic) and door mirror position] can be
adjusted with the power seat switch or ADP steering switch or door mirror remote control switch.
NOTE:
The seat can be manually operated with the ignition switch OFF.
The door mirrors can be manually operated with the ignition switch turned ACC or ON.
A U T O M AT I C O P E R AT I O N
NOTE:
Disconnecting the battery erases the stored memory.
After connecting the battery, insert the key into the ignition cylinder and turn the driver door switch ON (open) →OFF (close) →ON
(open), the Entry/ Exiting operation becomes possible.
After exiting operation is carried out, return operation can be operated.
NOTE:
During automatic operation, if the ignition switch is turned ON →START, the automatic operation is suspended. When the ignition switch
returns to ON, it resumes. Function Description
Memory switch operation The seat, steering and door mirror move to the stored driving position by pushing
memory switch (1 or 2).
Entry/Exiting function Exiting operation At exit, the seat moves backward and steering wheel moves forward/upward.
Entry operation
At entry, the seat and steering wheel returns from the exiting position to the previous
driving position.
keyfob interlock operation Perform memory operation, exiting operation and entry operation by pressing keyfob
unlock button.
Auto operation temporary stop
conditions. When ignition switch turned to START during memory switch operation and return opera-
tion, memory switch operation and entry operation is stopped.
Auto operation stop conditions.
When the vehicle speed becomes 7 km/h (4 MPH) or higher.
When the setting switch, memory switch 1, or 2 are pressed.
When A/T selector lever is in any position other than P.
When the door mirror remote control switch is operated (when ignition switch turned to
ON or ACC).
When power seat switch turned ON.
When ADP steering switch turned ON (telescopic operation or tilt operation).
When door mirror operates (only memory switch operation).
When driver seat sliding Entry/Exiting setting is OFF (only entry/exiting operation).
When steering wheel tilt and telescopic Entry/Exiting setting is OFF (only entry/exiting
operation).
When the tilt and telescopic sensor malfunction is detected.

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 steering wheel operation is cancelled, the system performs seat and mirror operation only.
If Entry/Exiting operation is cancelled, the system performs steering wheel operation and mirror operation
only.
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 MO DE
When any manual and automatic operations are not performed, if any motor operations of seats or tilt of steer-
ing are detected for approx. 0.1 sec or more, status is judged “Output malfunction”. Motor operation will be
suspended automatically, and all automatic operations will be ineffective (in this case, the motor will not oper-
ate manually).
CANCEL OF FAIL-SAFE MODE
The mode is cancelled when the selector lever is shifted to P position from any other position.
