When the hazard switch is depressed, ground is supplied

through BCM terminal 29
to hazard switch terminal 2
through hazard switch terminal 1
to grounds M57, M61 and M79.

When the hazard switch is depressed, BCM (body control module) outputs turn signal from BCM (body control module) terminals 45 and 46, interpreting it as turn signal is ON.

The BCM (body control module) supplies power

through front combination lamp LH and RH terminal 10
to grounds E15 and E24
