Hazard Lamp Operation

WARNING: This page is about a different car, the 2004 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.

Power is supplied at all times

through 50A fusible link (letter j, located in the fuse and fusible link box)
to BCM (body control module) terminal 55, and
through 15A fuse [No. 19, located in the fuse block (J/B)]
to combination meter terminal 31.
Ground is supplied
through BCM (body control module) terminals 49 and 52
through combination meter terminal 32
to grounds M57, M61 and M79.
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 supplies power
from terminals 45 and 46
to front combination lamp LH and RH terminal 2
through front combination lamp LH and RH terminal 1
to grounds E9, E15 and E24, and
to rear combination lamp LH terminal 3
through rear combination lamp LH terminal 5
to grounds B7 and B19, and
to rear combination lamp RH terminal 3
through rear combination lamp terminal 5
to grounds B117 and B132.

BCM (body control module) sends signal to combination meter through CAN communication lines, and turns on turn signal indicator lamps within combination meter.
