System DescriptionNIS00015
INPUTS
Power is supplied at all times
through 40A fusible link (letter F , located in the fuse and fusible link box)
to BCM terminal 55,
through 10A fuse [No.18, located in the fuse block (J/B)]
to BCM terminal 42,
through 10A fuse [No. 21, located in the fuse block (J/B)]
to key switch terminal 2.
When the ignition switch is ON or START position, power is supplied
through 10A fuse [No.1, located in the fuse block (J/B)]
to BCM terminal 38.
When the ignition switch is ACC or ON position, power is supplied
through 10A fuse [No. 6, located in the fuse block (J/B)]
to BCM terminal 11.
Ground is supplied
to BCM terminal 52
through body grounds M30 and M66.
When the driver side door switch is ON (door is OPEN), ground is supplied
to BCM terminal 62
through driver side door switch terminal 1 and
through driver door switch case ground.
When the passenger side door switch is ON (door is OPEN), ground is supplied
to BCM terminal 12
through passenger side door switch terminal 1 and
through passenger side door switch case ground.
When the back door switch (For coupe models) is ON (door is OPEN), ground is supplied
to BCM terminal 58
through the back door switch terminals 1 and 3 and
through body grounds B5, B6, D105 and T14.
When the trunk lid lock assembly (trunk room lamp switch) (For roadster models) is ON (trunk is OPEN),
ground is supplied
to BCM terminal 57
through the trunk room lamp switch terminals 3 and 1 and
through body grounds B5,B6 and T14.
When the key switch is ON (key is inserted in ignition key cylinder), power is supplied
through key switch terminals 2 and 1
to BCM terminal 37.
Key fob signal is inputted to remote keyless entry receiver (the antenna of the system is built in remote keyless
entry receiver).
Remote keyless entry receiver sends keyfob signal
to BCM terminal 20
from remote keyless entry receiver terminal 2.
The remote keyless entry system controls operation of the
power door lock
hazard and horn reminder
auto door lock

Interior Lamp and Step Lamp Operation
When the following conditions come:
condition of interior lamp switch is DOOR position;
door switch OFF (when all the doors are closed);
Remote keyless entry system turns on interior lamp (for 30 seconds) with input of UNLOCK signal from key
fob.
For detailed description, refer to LT- 1 3 0 , "
MAP LAMP TIMER OPERATION" .
Panic Alarm Operation
When key switch is OFF (when ignition key is not inserted in key cylinder), BCM turns on and off horn and
headlamp intermittently with input of PANIC ALARM signal from key fob.
The alarm automatically turns off after 25 seconds or when BCM receives any signal from key fob.
For detailed description, refer to BL-128, "
PANIC ALARM OPERATION" .
Back Door Operation/For Coupe
When a BACK DOOR OPEN signal is sent with key OFF (ignition key removed from key cylinder) from key
fob, power is supplied through BCM terminal 19.
When power and ground are supplied, back door opener actuator opens back door.
Trunk Opener Operation/For Roadster
When a TRUNK OPEN signal is sent with key OFF (ignition key removed from key cylinder) from key fob,
power is supplied through BCM terminal 19.
When power and ground are supplied, trunk lid opener actuator opens trunk.
Keyless Power Window Down (open) Operation
When key fob unlock switch is turned ON with ignition switch OFF, and key fob unlock switch is detected to be
on continuously for 3 seconds, the driver's door and passenger's door power windows are simultaneously
opened.
Power window is operated to open and the operation continues as long as the key fob unlock switch is
pressed.
CAN Communication System DescriptionNIS00016
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.
