LH Turn

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

• through BCM (body control module) terminal 45
• to front combination lamp LH terminal 6
• to rear combination lamp LH terminal 3.

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

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

The BCM also supplies input to combination meter terminals 27 and 28 across the CAN communication lines.

This input is processed by the unified meter control unit in the combination meter, which in turn supplies ground to the left turn signal indicator lamp.

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