LH Turn Signal Lamp

When the turn signal switch is moved to the left position, BCM output turn signal from BCM terminal 45, interpreting 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 lines, 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 combination 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.
