TURN SIGNAL AND HAZARD WARNING LAMPS
Revision: 2006 January2006 M35/M45
LH Turn Signal Lamp
When turn signal switch is moved to left position, BCM receives input signal requesting left turn signals to
flash. BCM then supplies power
through BCM terminal 45
to front combination lamp LH (turn signal) terminal 10
to side turn signal lamp LH terminal 1, and
to rear combination lamp LH (turn signal) terminal 3.
Ground is supplied
to front combination lamp LH (turn signal) terminal 9
to side turn signal lamp LH terminal 2
through grounds E22 and E43,
to rear combination lamp LH (turn signal) terminal 4
through grounds B5, B40 and B131.
The BCM also supplies input to unified meter and A/C amp. terminals 56 and 72 across the CAN communica-
tion lines.
The unified meter and A/C amp. which received the turn indicator signal makes the left turn signal indicator
turn on in combination meter.
With power and input supplied, the BCM controls the flashing of the LH turn signal lamps.
RH Turn Signal Lamp
When turn signal switch is moved to right position, BCM receives input signal requesting right turn signals to
flash. BCM then supplies power
through BCM terminal 46
to front combination lamp RH (turn signal) terminal 10
to side turn signal lamp RH terminal 1, and
to rear combination lamp RH (turn signal) terminal 3.
Ground is supplied
to front combination lamp RH (turn signal) terminal 9
to side turn signal lamp RH terminal 2
through grounds E22 and E43,
to rear combination lamp RH (turn signal) terminal 4
through grounds B5, B40 and B131.
The BCM also supplies input to unified meter and A/C amp. terminals 56 and 72 across the CAN communica-
tion lines.
The unified meter and A/C amp. which received the turn indicator signal makes the right turn signal indicator
turn on in combination meter.
With power and input supplied, the BCM controls the flashing of the RH turn signal lamps.
HAZARD LAMP OPERATION
Power is supplied at all times
through 50A fusible link (letter F, located in fuse, fusible link and relay block)
to BCM terminal 55,
through 10A fuse [No. 21, located in fuse block (J/B)]
to BCM terminal 42
to combination meter terminal 23,
through 10A fuse [No. 19, located in fuse block (J/B)]
to unified meter and A/C amp. terminal 54.
When the hazard switch is depressed, ground is supplied
to BCM terminal 29
through multifunction switch terminal 6.
Ground is supplied
to multifunction switch terminal 14

COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
CAN Communication System DescriptionNKS003RM
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNKS003RN
Refer to LAN-34, "CAN Communication Unit" .
