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.

Revision: 2006 January2006 M35/M45
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.
