FRONT FOG LAMP
Revision: 2007 April2007 M35/M45
FOG LAMP OPERATION
The fog lamp switch is built in combination switch. The lighting switch must be in 2ND position or AUTO posi-
tion (headlamp is ON) and fog lamp switch must be ON for fog lamp operation.
With the fog lamp switch in the ON position, the CPU located in IPDM E/R grounds coil side of the fog lamp
relay. Fog lamp relay then directs power

through IPDM E/R terminal 37

to front fog lamp RH terminal 1,

through IPDM E/R terminal 36

to front fog lamp LH terminal 1.
Ground is supplied

to front fog lamp RH terminal 2

through grounds E22 and E43,

to front fog lamp LH terminal 2

through grounds E22 and E43.
With power and grounds supplied, the front fog lamps illuminate.
The unified meter and A/C amp. that received the front fog lamp request signal by BCM across the CAN com-
munication makes a front fog lamp indicator lamp turn on in combination meter.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turned
from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, then the headlamps are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
CAN Communication System DescriptionNKS003R4
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.

With the ignition switch in the ON or START position, power is supplied

to CPU located in IPDM E/R,

through 15A fuse [No. 1, located in fuse block (J/B)]

to BCM terminal 38.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminal 52

through grounds M16 and M70,

to IPDM E/R terminals 38 and 51

through grounds E22 and E43.
OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives
input signal requesting the parking, license plate and tail lamps to illuminate. This input signal is communi-
cated to the IPDM E/R across the CAN communication lines. The CPU located in the IPDM E/R controls the
tail lamp relay coil, which when energized, directs power

through IPDM E/R terminal 21

to front combination lamp LH and RH terminals 5 (parking)

to front combination lamp LH and RH terminals 7 (side marker)

to rear combination lamp LH and RH terminals 1 (tail and side marker)

to license plate lamp LH and RH terminals 1.
Ground is supplied at all times

to front combination lamp LH and RH terminals 1 (parking and side marker)

through grounds E22 and E43,

to rear combination lamp LH and RH terminals 4 (tail and side marker)

through grounds B5, B40 and B131.

to license plate lamp LH and RH terminals 2

through grounds B402 and B405.
With power and ground supplied, the parking, license plate and tail lamps illuminate.
COMBINATION SWITCH READING FUNCTION
Refer toBCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 1ST (or 2ND) position, and ignition switch is turned
from ON or ACC to OFF, battery saver control feature is activated.
Under this condition, parking, license plate, side marker and tail lamps remain illuminated for 5 minutes, then
the parking, license plate, side marker and tail lamps are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.

ROOM LAMP TIMER OPERATION
BCM controls applicable lamps to illuminate for 15 seconds (can be set maximum 30 seconds) by timer oper-
ation under following conditions. BCM also controls applicable lamps to brighten for 1 second (can be set max-
imum 5 seconds) when turned ON, or to dim for 3 seconds (can be set maximum 5 seconds) when turned
OFF. (Timer operating time and dimming/brightening time can be changed with CONSULT-II. Refer to LT- 2 8 3 ,
"WORK SUPPORT (INT LAMP)" .) This control operates as follows.
Applicable lamps

Room lamp system: map lamp, foot lamp (driver side and passenger side) and personal lamp (rear LH
and rear RH).
BCM controls room lamp timer operation under following condition.

Condition 1: Door lock state changes.*
BCM judges as the door lock is unlocked under either case below.
–The Intelligent Key unit sends door lock/unlock trunk open request signal (driver side unlock or passenger
side unlock) to BCM through CAN communication line by unlock operation of intelligent key, outside key
antenna and front door request switch (driver side) or outside key antenna and front door request switch
(passenger side).
–Key cylinder switch state (unlock) signal is sent to BCM through power window serial link when front door
lock assembly (driver side) (key cylinder switch) is unlocked (ON) by power window main switch unlock
operation.
And fulfills all the conditions below.
–The engine switch (push switch) is OFF.
–All the doors are closed.
*: This setting can be changed by CONSULT-II. Refer to LT- 2 8 3 , "
WORK SUPPORT (INT LAMP)" .

Condition 2: Any door switch state changes.*
The BCM terminal value of operated door switch is changed when any door is opened and then closed.
From that BCM judges as the door is opened and then closed.
And fulfills all the conditions below.
–The engine switch (push switch) is OFF.
–All the doors are closed.
*: This setting can be changed by CONSULT-II. Refer to LT- 2 8 3 , "
WORK SUPPORT (INT LAMP)" .

Condition 3: Engine switch (push switch) state changes.*
The Intelligent Key unit judges as the engine switch (push switch) is OFF and sends push-button ignition
switch (push switch) signal to PDU (power distribution unit) when push-button ignition switch (push
switch) turned OFF. Then PDU (power distribution unit) turns OFF, IGN power supply and ACC power
supply.
And fulfills the conditions below.
–All the doors are closed.
*:This setting can be changed by CONSULT-II. Refer to LT- 2 8 3 , "
