DAYTIME LIGHT SYSTEM

System Description

NKS001OB

Daytime light system turns ON daytime light lamps (front fog lamps) while driving. Daytime light lamps are not
turned ON if engine is activated with parking brake ON. Release parking brake to turn on daytime light lamps.
The lamps turn OFF when lighting switch is in the 2ND position or AUTO position (headlamp is ON) and when
lighting switch is in the PASSING position. (Daytime light lamps are not turned off only by parking brake itself.)
A parking brake signal and engine run or stop signal are sent to BCM (body control module) by CAN commu-
nication line, and control daytime light system.

●

through 10A fuse [No. 21, located in fuse block (J/B)]

●

to combination meter terminal 21.

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

●

to ignition relay located in IPDM E/R,

●

through 10A fuse [No. 1, located in fuse block (J/B)]

●

When the ignition switch is in 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 M14 and M78,

●

to IPDM E/R terminals 38 and 60

●

through grounds E13, E26 and E28,

●

to combination meter terminals 22, 23 and 24

●

through grounds M14 and M78.

DAYTIME LIGHT OPERATION

Once the parking brake is turned OFF after ignition switch ON, if the lighting switch is turned OFF while engine
running, the BCM sends front fog lamp request signal (ON) through CAN communication.
When receiving front fog lamp request signal (ON), IPDM E/R turns ON front fog lamp relay in IPDM E/R.
IPDM E/R supplies power

●

through IPDM E/R terminal 37

●

to front fog lamp LH terminal 1,

●

through IPDM E/R terminal 36

●

to front fog lamp RH terminal 1.

Ground is supplied

●

to front fog lamp RH and LH terminals 2

●

through grounds E13, E26 and E28.

With power and ground supplied, front fog lamp illuminate.

COMBINATION SWITCH READING FUNCTION

Refer to 

BCS-3, "COMBINATION SWITCH READING FUNCTION"

 .

EXTERIOR LAMP BATTERY SAVER CONTROL

With 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 front fog lamps remain illuminated for 5 minutes, and then the front fog lamps are
turned off.
Exterior lamp battery saver control made can be changed by the function setting of CONSULT-II.

AUTO LIGHT OPERATION

For auto light operation, refer to 

LT-81, "System Description"

  in “AUTO LIGHT SYSTEM”. 

CAN Communication System Description

NKS001OC

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.
