HEADLAMP (FOR USA)
HEADLAMP (FOR USA)
Component Parts and Harness Connector LocationINFOID:0000000005394875
System DescriptionINFOID:0000000005394876
Headlamp operation is controlled by the BCM (body c ontrol module) based on inputs from the combination
switch (lighting switch). When the lighting switch is pl aced in the 2ND position, the BCM receives an input sig-
nal requesting the headlamps (and tail lamps) illuminate. The BCM sends a signal, via the CAN communica-
tion lines, to the IPDM E/R (intelligent power di stribution module engine room) requesting the headlamps be
turned ON. The CPU (central processing 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.
OUTLINE
Power is supplied at all times
• to headlamp high relay RH and LH (located in IPDM E/R),
• to headlamp low relay (located in IPDM E/R),

HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in 2ND position, the BCM re ceives an input signal requesting the headlamps to illumi-
nate. The BCM then sends a signal, via the CAN comm unication lines, to the IPDM E/R requesting the low
beam headlamps be turned ON. The CPU located in the IPDM E/R controls ground to 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 headlamp RH terminal 3, and
• through 15A fuse (No. 40, located in IPDM E/R)
• through IPDM E/R terminal 52
• to headlamp LH terminal 3.
Ground is supplied
• to headlamp RH and LH terminals 2
• through grounds E15 and E24.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and high beam switch in the HIGH position, the BCM receives an 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 then communicated to the IPDM E/R and the combination
meter via the CAN communication. The CPU located in the IPDM E/R controls the headlamp high relays (LH
and RH), which when energized, directs power
• through 10A fuse (No. 34, located in IPDM E/R)
• through IPDM E/R terminal 56
• to headlamp RH terminal 1, and
• through 10A fuse (No. 35, located in IPDM E/R)
• through IPDM E/R terminal 55
• to headlamp LH terminal 1.
Ground is supplied
• to headlamp RH and LH terminal 2
• through grounds E15 and E24.
With power and ground supplied, the high beam headlamps illuminate.
The BCM sends a signal, via the CAN communication lines, to the combination meter requesting the high
beam indicator lamp be turned ON.

switch (lighting switch). When the lighting switch is pl aced 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

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.
