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 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 (When Daytime Light Does Not Operate)/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH BEAM or PASSING position, the BCM receives
input signal requesting headlamp high beams to illuminate. High beam request signal is communicated to the
IPDM E/R across the CAN communication lines. The CPU located in the IPDM E/R controls headlamp high
relay coil and low relay coil, which when energized, directs power
through 10A fuse (No. 72, located in IPDM E/R)
through IPDM E/R terminal 27
through front combination lamp RH terminals 6 and 2
to daytime light relay terminal 3,
through 10A fuse (No. 74, located in IPDM E/R)
through IPDM E/R terminal 28
to front combination lamp LH terminal 6,
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 daytime light relay terminal 4
to front combination lamp RH terminal 4
to front combination lamp LH terminal 2
to front combination lamp LH terminal 4
through grounds E22 and E43.
With the power and ground supplied, the headlamp high beam and low headlamp illuminate.
High beam indicator illuminates when combination meter receives input signal requesting high beam indicator
to illuminate. This is communicated to BCM across the CAN communication lines.
