TURN SIGNAL AND HAZARD WARNING LAMPS
Revision: November 20092006 QX56
through door mirror LH and RH terminal 11
to grounds M57, M61 and M79 and
to rear turn signal lamp LH terminal 1
through rear turn signal lamp LH terminal 3
to grounds B7 and B19, and
to rear turn signal lamp RH terminal 4
through rear turn signal lamp RH terminal 6
to grounds B117 and B132.
BCM sends signal to combination meter through CAN communication lines, and turns on turn signal indicator
lamps within combination meter.
REMOTE KEYLESS ENTRY SYSTEM OPERATION
Power is supplied at all times
through 50A fusible link (letter f , located in the fuse and fusible link box)
to BCM terminal 70, and
through 10A fuse [No. 19, located in the fuse block (J/B)]
to combination meter terminal 8.
Ground is supplied
to BCM terminal 67 and
to combination meter terminal 17
through grounds M57, M61 and M79.
When the remote keyless entry system is triggered by input from the keyfob, the BCM, interpreting it as turn
signal is ON, outputs turn signal from BCM terminals 60 and 61.
The BCM supplies power
through BCM terminals 60 and 61
to front turn/fog lamp LH and RH terminal 2
through front turn/fog lamp LH and RH terminal 3
to grounds E9, E15 and E24, and
to door mirror LH and RH terminal 15
through door mirror LH and RH terminal 11
to grounds M57, M61 and M79 and
to rear turn signal lamp LH terminal 1
through rear turn signal lamp LH terminal 3
to grounds B7 and B19, and
to rear turn signal lamp RH terminal 4
through rear turn signal lamp RH terminal 6
to grounds B117 and B132.
BCM 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 keyfob is
used to activate the remote keyless entry system.
