HEADLAMP (FOR CANADA) - DAYTIME LIGHT SYSTEM -PFP:26010
Component Parts and Harness Connector LocationEKS00ICD
System DescriptionEKS00ICE
Headlamp operation is controlled by the BCM (body control module) based on inputs from the combination
switch (lighting switch). When the lighting switch is placed in the 2ND position, the BCM receives an input sig-
nal requesting the headlamps (and tail lamps) illuminate. The request is then communicated to the IPDM E/R
(intelligent power distribution module engine room) via the CAN communication lines. The CPU (central pro-
cessing unit) located in the IPDM E/R controls ground for the headlamp high and headlamp low relay coils.
These relays direct power to the respective headlamps, which then illuminate. When the headlamp switch is
OFF or in the 1ST position (parking lamps ON), the parking brake is released and the engine is running, the
IPDM E/R de-energizes the headlamp relays and supplies ground to the daytime light relay 1 to actuate the
daytime light function.

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

to BCM terminal 38,

through 10A fuse [No. 3, located in fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminal 67 and

to IPDM E/R terminals 39 and 59

through grounds E15 and E24,
HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives an input signal requesting the headlamps to illumi-
nate. This input signal is communicated to the IPDM E/R via the CAN communication lines. The CPU located
in the IPDM E/R controls the headlamp low relay coil, which when energized, directs power

through 15A fuse (No. 41, located in IPDM E/R)

through IPDM E/R terminal 54

to daytime light relay 2 terminals 1 and 5 (energizing the relay),

through daytime light relay 2 terminal 3

to front combination lamp RH terminal 3, and

through 15A fuse (No. 40, located in IPDM E/R)

through IPDM E/R terminal 52

to front combination lamp LH terminal 3.
Ground is supplied

to front combination lamp LH terminal 2

through grounds E15 and E24,

to headlamp RH terminal 2 via

daytime light relay 1 terminals 3 and 4

through grounds E15 and E24.
With power and ground supplied, low beam headlamps illuminate.
High Beam/Flash-to-Pass Operation
With the lighting switch in 2ND position and high beam switch in the HIGH position, the BCM receives input
signal requesting the headlamp high beams to illuminate. The flash-to-pass feature can be used any time and
also sends a signal to the BCM. This input signal is communicated to the IPDM E/R and the combination
meter via the CAN communication lines. The CPU located in the IPDM E/R controls the headlamp high relay
coil, which when energized, directs power

through 10A fuse (No. 34, located in IPDM E/R)

through IPDM E/R terminal 56

to front combination lamp RH terminal 1, and

through 10A fuse (No. 35, located in IPDM E/R)

through IPDM E/R terminal 55

to front combination lamp LH terminal 1.
Ground is supplied

to front combination lamp LH terminal 2

through grounds E15 and E24, and

to front combination lamp RH terminal 2 via

daytime light relay 1 terminals 3 and 4

through grounds E15 and E24.
With power and ground supplied, the high beam headlamps illuminate.
The BCM sends a signal to the combination meter requesting the high beam indicator lamp to turn ON.
Daytime Light System Operation
With the lighting switch in the OFF or 1ST position (parking lamps ON), the BCM receives inputs requesting
the headlights off. If the parking brake is released and the engine is running, the BCM then sends a signal, via
the CAN communication lines, requesting the IPDM E/R to activate the daytime light system. The CPU located
in the IPDM E/R controls the daytime light relay 1 coil, which when energized, directs power

from daytime light relay 1 terminal 3

to front combination lamp RH terminal 2,

through front combination lamp RH high beam terminal 1

to IPDM E/R terminal 56,

through 10A fuse (No. 34, located in IPDM E/R) and

through both de-energized headlamp high relays

to 10A fuse (No. 35, located in IPDM E/R),

through IPDM E/R terminal 55

to front combination lamp LH terminal high beam 1.
Ground is supplied

to front combination lamp LH terminal 2

through grounds E15 and E24,

to daytime light relay 1 terminal 1

through IPDM E/R terminal 6.
With power and ground supplied, high beam headlamps illuminate at reduced intensity.
