Component Parts and Harness Connector LocationINFOID:0000000005929049
System DescriptionINFOID:0000000005929050
Headlamp operation is controlled by the BCM (body c ontrol module) based on inputs from the combination
switch (lighting and turn signal switch). When the light ing switch is placed in the 2ND position, the BCM
receives an input signal requesting the headlamps (and ta il lamps) illuminate. The request is then communi-
cated to the IPDM E/R (intelligent power distribution module engine room) via the CAN communication lines.
The CPU (central processing unit) located in t he IPDM E/R controls ground for the headlamp high and head-
lamp 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.
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) and
• to ignition relay (located in IPDM E/R)

• through 20A fuse (No. 53, located in IPDM E/R)
• to CPU located in IPDM E/R,

• through 10A fuse [No. 3, located in fuse block (J/B)]
• to combination meter terminal 28.
With the ignition switch in the ACC or ON position, power is supplied
• through 10A fuse [No. 20, located in fuse block (J/B)]
• to BCM terminal 11.
Ground is supplied
• to BCM terminal 67 and
• to combination meter terminals 21, 22 and 23
• through grounds M57 and M61,
• 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 re ceives 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 re lay 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 s witch 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 locat ed 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
