DAYTIME LIGHT SYSTEMPFP:284B2
Component Parts and Harness Connector LocationNKS002VW
System DescriptionNKS002VX
Daytime light system turns ON daytime light 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 the lighting switch is in the 2ND position or AUTO position (headlamp is ON) and when the
lighting switch is in the PASSING position (daytime light lamps are not turned OFF only by parking brake
itself).
The parking brake signal and engine run or stop signal are sent to BCM (body control module) by CAN com-
munication line, and control daytime light system.
OUTLINE
Power is supplied at all times

through 10A fuse [No. 19, located in fuse block (J/B)]

to combination meter terminal 8,

through 15A fuse [No. 22, located in fuse block (J/B)]

to BCM terminal 42,

to BCM terminal 55,

through 10A fuse (No. 36, located in fuse, fusible link and relay box)

to daytime light relay terminals 2 and 5.
When ignition switch is in ON or START position, power is supplied

through 10A fuse [No. 12, located in fuse block (J/B)]

to combination meter terminal 7,

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

to BCM terminal 38.
Ground is supplied

to combination meter terminals 5, 6 and 15

through grounds M35, M45 and M85,

to BCM terminals 49 and 52

through grounds M35, M45 and M85.
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 daytime light request signal (ON) through CAN communication.
When receiving daytime light request signal (ON), combination meter turns ON daytime light relay. And power
is supplied

through daytime light relay terminal 1

to combination meter terminal 10,

through daytime light relay terminal 3

to parking lamp RH and LH terminals 1.
Ground is supplied

to combination meter terminals 5, 6 and 15

through grounds M35, M45 and M85,

to parking lamp RH and LH terminals 3

through grounds E21, E50 and E51.
With power and grounds supplied, the daytime light lamps illuminate.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
AUTO LIGHT OPERATION
Refer to LT- 5 6 , "System Description" .
CAN Communication System DescriptionNKS002VY
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 UnitNKS002VZ
