LH Turn

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

• To front combination lamp LH terminal 6
• To rear combination lamp LH terminal 3
• Through BCM terminal 45.

Ground is supplied to front combination lamp LH terminal 4 through grounds E17 and E43.

Ground is supplied to rear combination lamp LH terminal 4 through ground B103.

The BCM also supplies input to combination meter terminals 27 and 28 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.
