Hazard Lamp Operation

Power is supplied at all times

through 50A fusible link (letter M, located in fuse, fusible link and relay box)
to BCM terminal 55,
through 10A fuse [No. 19, located in fuse block (J/B)]
to combination meter terminal 8,
through 10A fuse [No. 20, located in fuse block (J/B)]
to rear combination lamp control unit terminal 1.

Ground is supplied

through BCM terminals 49 and 52
to grounds M35, M45 and M85,
through rear combination lamp control unit terminal 7
to grounds E21, E50 and E51,
through combination meter terminals 5, 6 and 15
to grounds M35, M45 and M85.

When 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.

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.

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.
