LH Turn Signal Lamp

When turn signal switch is moved to left position, BCM receives input signal requesting left turn signals to flash. BCM then supplies power

through BCM terminal 45
to front combination lamp LH terminal 6, and
to rear combination lamp LH terminal 3.

Ground is supplied

to front combination lamp LH terminal 4
through grounds E17 and E43,
to rear combination lamp LH terminal 4
through ground B103.

The BCM also supplies input to combination meter terminals 4 and 5 across CAN communication lines. This input is processed by unified meter control unit in combination meter, which in turn supplies ground to the left turn signal indicator lamp.

With power and input supplied, BCM controls flashing of LH turn signal lamps.
