Ground is supplied
lto front combination lamp LH terminal 2
lto side turn signal lamp LH terminal 2 and
lto rear combination lamp LH terminal 3
lthrough ground E21, E41 and E61.
The BCM also supplies input to combination meter terminals 11 and 12 through the CAN communication. This
input is processed by unified meter control unit in combination meter, which in turn supplies ground to the left
turn signal indicator lamp.
With power and input supplied, BCM controls flashing of LH turn signal lamps.
RH Turn
When the turn signal switch is moved to the right position, BCM receives input signal requesting right turn sig-
nals to flash.
BCM then supplies power
lthrough BCM terminal 48
lto front combination lamp RH terminal 1
lto side turn signal lamp RH terminal 1 and
lto rear combination lamp RH terminal 2.
Ground is supplied
lto front combination lamp RH terminal 2
lto side turn signal lamp RH terminal 2 and
lto rear combination lamp RH terminal 3
lthrough ground E21, E41 and E61.
The BCM also supplies input to combination meter terminals 11 and 12 through the CAN communication. This
input is processed by unified meter control unit in combination meter, which in turn supplies ground to the right
turn signal indicator lamp.
With power and input supplied, BCM controls flashing of RH turn signal lamps.
HAZARD LAMP OPERATION
Power is supplied at all times
lthrough 50A fusible link (letter G, located in fuse and fusible link box)
lto BCM terminal 57,
lthrough 10A fuse [No. 19, located in fuse block (J/B)]
lto combination meter terminal 3.
Ground is supplied
lto BCM terminal 55 and
lto combination meter terminal 23
lthrough grounds M21, M80 and M83.
When the hazard switch is depressed, ground is supplied
lto BCM terminal 33
lthrough hazard switch terminal 2
lthrough hazard switch terminal 1
lthrough grounds M21, M80 and M83.
When the hazard switch is depressed, BCM receives input signal requesting turn signals to flash.
BCM then supplies power
lthrough BCM terminal 47
lto front combination lamp LH terminal 1
lto side turn signal lamp LH terminal 1 and
lto rear combination lamp LH terminal 2,
