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
