OUTLINE
Power is supplied at all times
• through 50A fusible link (letter f , located in the fuse and fusible link box)
• to BCM (body control module) terminal 70, and
• through 10A fuse [No. 19, located in the fuse block (J/B)]
• to combination meter terminal 8.
TURN SIGNAL OPERATION
When the ignition switch is in the ON or START position, power is supplied
• through 10A fuse (No. 59, located in the fuse and relay box)
• to BCM terminal 38, and
• through 10A fuse [No. 14, located in the fuse block (J/B)]
• to combination meter terminal 24.
Ground is supplied
• to BCM terminal 67 and
• to combination meter terminal 17
• through grounds M57, M61 and M79.
LH Turn
When the turn signal switch is moved to the left position, the BCM, interpreting it as turn signal is ON, outputs
turn signal from BCM terminal 60.
The BCM supplies power
• through BCM terminal 60
• to front turn/fog lamp LH terminal 2
• through front turn/fog lamp LH terminal 3
• to grounds E9, E15 and E24,
• to door mirror LH terminal 15

TURN SIGNAL AND HAZARD WARNING LAMPS
• to rear combination lamp LH terminal 4
• through rear combination signal lamp LH terminal 6
• 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,
• to door mirror RH terminal 15
• through door mirror RH terminal 11
• to grounds M57, M61 and M79 and
• to rear combination lamp RH terminal 4
• through rear combination lamp terminal 6
• to grounds B117 and B132.
BCM sends signal to combination meter through CAN communication lines, and turns on turn signal indicator
lamp within combination meter.
HAZARD LAMP 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 hazard switch is depressed, ground is supplied
• to BCM terminal 29
• through hazard switch terminal 2
• through hazard switch terminal 1
• through grounds M57, M61 and M79.
When the hazard switch is depressed, the BCM, interpreting it as hazard warning lamps are 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,
• to door mirror LH and RH terminal 15
