through 50A fusible link (letter j, located in the fuse and fusible link box)
to BCM (body control module) terminal 55, and
through 10A fuse [No. 3, located in the fuse block (J/B)]
to BCM (body control module) terminal 42, and
through 15A fuse [No. 19, located in the fuse block (J/B)]
to combination meter terminal 31.
Ground is supplied
to BCM (body control module) terminals 49 and 52 and

When the remote keyless entry system is triggered by input from the key fob, BCM (body control module) output 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.

With power and input supplied, the BCM controls the flashing of the hazard warning lamps when key fob is used to activate the remote keyless entry system.
