to grounds B7 and B19.
BCM sends signal to combination meter through CAN communication lines, and turns on turn signal indicator
lamp within combination meter.
RH Turn
When the turn signal switch is moved to the right position, the BCM, interpreting it as turn signal is ON, outputs
turn signal from BCM terminal 61.
The BCM supplies power

through BCM terminal 61

to front turn/fog lamp RH terminal 2

through front turn/fog lamp RH terminal 3

to grounds E9, E15 and E24, and

to rear turn signal lamp RH terminal 1

through rear signal lamp terminal 3

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 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 1

through rear turn signal lamp RH terminal 3

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.
