lto combination meter terminal 16.
Ground is supplied at all times
lto BCM terminal 55 and
lto combination meter terminal 23
lthrough grounds M21, M80 and M83,
lto IPDM E/R terminals 38 and 59
lthrough grounds E21, E41 and E61.
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input requesting the headlamps to illuminate. This
input is communicated to the IPDM E/R through the CAN communication. The CPU of the IPDM E/R controls
the headlamp low relay coil. When energized, this relay directs power
lthrough 15A fuse (No. 41, located in IPDM E/R)
lthrough IPDM E/R terminal 54
lto front combination lamp RH terminal 1,
lthrough 15A fuse (No. 40, located in IPDM E/R)
lthrough IPDM E/R terminal 52
lto front combination lamp LH terminal 1.
Ground is supplied
lto front combination lamp RH and LH terminals 3
lthrough grounds E21, E41 and E61.
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 request-
ing the headlamp high beams to illuminate. This input is communicated to the IPDM E/R through the CAN
communication. The CPU of the IPDM E/R controls the headlamp high relay coil. When energized, this relay
directs power
lthrough 10A fuse (No. 34, located in IPDM E/R)
lthrough IPDM E/R terminal 56
lto front combination lamp RH terminal 2,
lthrough 10A fuse (No. 35, located in IPDM E/R)
lthrough IPDM E/R terminal 55
lto front combination lamp LH terminal 2.
Ground is supplied
lto front combination lamp RH and LH terminals 3
lthrough grounds E21, E41 and E61.
With power and ground supplied, the high beam headlamps illuminate.
Combination meter that received high beam request signal by BCM through the CAN communication makes a
high beam indicator lamp turn on in combination meter.
FRIENDLY LIGHTING FUNCTION
This function starts timer function of BCM by operating passing switch, and illuminates headlamps (LOW
beam) for a given length of time.
Headlamps (LOW beam) stay ON for a given length of time by operating passing switch when ignition switch is
OFF and lighting switch is OFF.
Headlamps (LOW beam) stays ON for two minutes at a maximum by operating passing switch repeatedly.
CONSULT-II is capable of setting a lighting time. Refer toLT- 1 6 , "
WORK SUPPORT".
