HEADLAMP (FOR USA)
HEADLAMP (FOR USA)
Component Parts and Harness Connector LocationINFOID:0000000001704360
System DescriptionINFOID:0000000001704361
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 BCM sends a signal, via the CAN communica-
tion lines, to the IPDM E/R (intelligent power distribution 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),
• to ignition relay (located in IPDM E/R),
• through 15A fuse (No. 52, located in IPDM E/R) and

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.
