HEADLAMP (FOR CANADA) - DAYTIME LIGHT SYSTEM -PFP:26010
Component Parts and Harness Connector LocationNKS003P9
System DescriptionNKS003PA
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. Take off parking brake to turn on daytime light lamps. The lamps
turn off when lighting switch is in the 2ND position or AUTO position (Head lamp 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.

DAYTIME LIGHT OPERATION
With the engine running, the lighting switch in the OFF or AUTO position (headlamp is not illuminate) and
parking brake released, the IPDM E/R receives input request signal from BCM to turn on daytime light. This
input is communicated across the CAN communication lines. The CPU of the IPDM E/R controls the daytime
light relay coil. When energized, this relay directs power

through daytime light relay terminals 5 and 3

through front combination lamp RH terminal 2

through front combination lamp RH terminal 6

through IPDM E/R terminal 27

through 10A fuse (No. 72, located in IPDM E/R)

through 10A fuse (No. 74, located in IPDM E/R)

through IPDM E/R terminal 28

to front combination lamp LH terminal 6.
Ground is supplied

to combination lamp LH terminal 2

through grounds E22 and E43.
With power and grounds supplied, the daytime lights illuminate. The high beam headlamps are now wired in
series and illuminate at a reduced intensity.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
AUTO LIGHT OPERATION
For auto light operation, refer to LT- 11 5 , "System Description" .
CAN Communication System DescriptionNKS004HQ
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 UnitNKS004HR
Refer to LAN-50, "CAN System Specification Chart" .

How to Perform Trouble DiagnosisNKS003PG
1. Confirm the symptom or customer complaint.
2. Understand operation description and function description. Refer to LT- 7 8 , "
System Description" .
3. Perform the Preliminary Check. Refer to LT- 9 2 , "
Preliminary Check" .
4. Check symptom and repair or replace the cause of malfunction.
5. Does the headlamp operate normally? If YES: GO TO 6. If NO: GO TO 4.
