TURN SIGNAL AND HAZARD WARNING LAMPSPFP:26120
Component Parts and Harness Connector LocationEKS00B9P
System DescriptionEKS00B9Q
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

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

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
