When the turn signal switch is moved to the left position, BCM output turn signal from BCM terminal 45, inter-
preting it as turn signal is ON.
Connected from BCM terminal 45 to front combination lamp LH terminal 4.
Turn signal lamp turns ON
• through front combination lamp LH terminal 8
• to grounds E21, E50 and E51.
Connected from BCM terminal 45 to rear combination lamp control unit terminal 4.
Rear turn signal (LED) turns ON
• through rear combination lamp control unit terminal 11
• to rear combination lamp LH terminal 3,
• through rear combination lamp LH terminal 4
• to rear combination lamp control unit terminal 10.
BCM sends signal to the unified meter and A/C amp. through CAN communication, and turns ON turn signal
indicator lamp with combination meter.
When rear turn signal lamp (LED) does not turn ON, rear combination lamp control unit sends signal to combi-
nation meter. And then unified meter and A/C amp. ends turn LED burnout status signal to BCM through CAN
communication lines for speeding up turn signal blinking.
RH Turn Signal Lamp
When the turn signal switch is moved to right position, BCM output turn signal from BCM terminal 46, interpret-
ing it as turn signal is ON.
Connected from BCM terminal 46 to front combination lamp RH terminal 4.
Turn signal lamp turns ON
• through front combination lamp RH terminal 8
• to grounds E21, E50 and E51.
Connected form BCM terminal 46 to rear combination lamp control unit terminal 5.
Rear turn signal (LED) turns ON
• through rear combination lamp control unit terminal 9
• to rear combination lamp RH terminal 3,
• through rear combination lamp RH terminal 4
• to rear combination lamp control unit terminal 8.
BCM sends signal to the unified meter and A/C amp. through CAN communication, and turns ON turn signal
indicator lamp with combination meter.
When rear turn signal lamp (LED) does not turn ON, rear combination lamp control unit sends signal to combi-
nation meter. And then unified meter and A/C amp. ends turn LED burnout status signal to BCM through CAN
communication lines for speeding up turn signal blinking.
HAZARD LAMP OPERATION
When the hazard switch is depressed, BCM output turn signal from BCM terminals 45 and 46, interpreting it as
turn signal is ON.
Connected from BCM terminal 45 and 46 to front combination lamp RH and LH terminals 4.
Turn signal lamp turns ON
• through front combination lamp RH and LH terminals 8
• to grounds E21, E50 and E51.
Connected form BCM terminals 45 and 46 to rear combination lamp control unit terminals 4 and 5.
Rear turn signal (LED) turns ON
• through rear combination lamp control unit terminal 11
• to rear combination lamp LH terminal 3,
• through rear combination lamp LH terminal 4
• to rear combination lamp control unit terminal 10,
• through rear combination lamp control unit terminal 9
• to rear combination lamp RH terminal 3,
• through rear combination lamp RH terminal 4
• to rear combination lamp control unit terminal 8.
And hazard switch is depressed, ground is supplied
• to hazard switch terminal 2
• through BCM terminal 29,
• to grounds M35, M45 and M85
• through hazard switch terminal 1.
BCM sends signal to the unified meter and A/C amp. through CAN communication, and turns ON turn signal
indicator lamp with combination meter.
