INSPECTION PARKING BRAKE SWITCH CIRCUIT
1. CHECK BRAKE INDICATOR
1. Turn ignition switch ON.
2. When a parking brake is made ON/OFF, it checks whether brake indicator lamp of combination meter lights up / puts out the light.

AUTO LIGHT SYSTEM
Revision: 2006 July 2007 FX35/FX45
When ignition switch is turn to ON position, and
When outside brightness is darker than prescribed level, input is supplied

from optical sensor terminal 2

to BCM terminal 14
The headlamps will then illuminate. For a description of headlamp operation, Refer to LT- 5 5 , "
System Descrip-
tion" .
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
DELAY TIMER FUNCTION
Delay timer function carries out a function that BCM activates the timer and controls lights out of headlamps by
door switch signal and lightning switch signal when turning the Ignition switch OFF while it is ON and head-
lamps are ON by the auto light function.
Timer types are a 5 minute timer and a 45 second timer

When opening any door (door switch is ON), the 5 minute timer starts and then headlamps go out 5 min-
utes later

When all the doors are closed (from door switch ON to OFF), the 45 second timer starts and then head-
lamps go out 45 seconds later. If any door is opened (door switch ON) while the 45 second timer is in
operation, the 5 minute timer starts again

The timer stops when turning on the ignition switch or turning off the auto light switch under the above
conditions.
Delay timer control mode can be changed by the function setting of CONSULT-II or display.
CAN Communication System DescriptionNKS002WD
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 UnitNKS002WE
Refer to LAN-49, "CAN System Specification Chart" .
Major Components and FunctionsNKS002WF
Components Functions
BCM

Turns on/off circuits of tail light and headlamp according to signals from light sensor, lighting switch
(AUTO), driver door switch, passenger door switch, rear door switch, and ignition switch (ON, OFF).
Optical sensor

Converts outside brightness (lux) to voltage, and sends it to BCM. (Detects brightness of 800 to 2,500 lux)

Trouble phenomenon Malfunction system and reference

Parking, license plate, side marker and tail lamps and
headlamps will not illuminate when outside of the vehicle
becomes dark. (Lighting switch 1ST position and 2ND posi-
tion operate normally.)

Parking, license plate, side marker and tail lamps and
headlamp will not go out when outside of the vehicle
becomes light. (Lighting switch 1ST position and 2nd posi-
tion operate normally.)

Headlamps go out when outside of the vehicle becomes
light, but parking lamps stay on.

Refer to LT- 6 6 , "WORK SUPPORT" .

Refer to LT- 7 0 , "Lighting Switch Inspection" .

Refer to LT- 7 0 , "Optical sensor System Inspection" .
If above systems are normal, replace BCM.
Shut off delay feature will not operate.

CAN communication line inspection between BCM and combina-
tion meter. Refer to BCS-13, "
CAN Communication Inspection
Using CONSULT-II (Self-Diagnosis)" .

Refer to BL-40, "Check Door Switch" .
If above system is normal, replace BCM.
