HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input signal requesting the headlamps to illuminate.
This input signal is communicated to the IPDM E/R across 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. 76, located in IPDM E/R)

through IPDM E/R terminal 20

to front combination lamp RH terminal 8,

through 15A fuse (No. 86, located in IPDM E/R)

through IPDM E/R terminal 30

to front combination lamp LH terminal 8.
Ground is supplied

to front combination lamp RH terminal 4

to front combination lamp LH terminal 4

through grounds E22 and E43.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM receives input signal
requesting the headlamp high beams and low beams to illuminate. This input signal is communicated to the
IPDM E/R across the CAN communication lines. The CPU located in the IPDM E/R controls the headlamp
high relay coil and low relay coil, which when energized, directs power

through 15A fuse (No. 76, located in IPDM E/R)

through IPDM E/R terminal 20

to front combination lamp RH terminal 8,

through 15A fuse (No. 86, located in IPDM E/R)

through IPDM E/R terminal 30

to front combination lamp LH terminal 8,

through 10A fuse (No. 72, located in IPDM E/R)

through IPDM E/R terminal 27

to front combination lamp RH terminal 6,

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 front combination lamp RH terminal 4

to front combination lamp LH terminal 4

to front combination lamp RH terminal 2

to front combination lamp LH terminal 2

through grounds E22 and E43.
With power and ground supplied, the high beam and low beam headlamps illuminate.
The unified meter and A/C amp. that received the high beam request signal by BCM across the CAN commu-
nication makes a high beam indicator lamp turn on in the combination meter.
