RH Turn
When the turn signal switch (combination switch) is moved to the right position, the BCM (body control module) receives input signal requesting the right turn signals to flash. The BCM then supplies power
- through BCM (body control module) terminal 46
- to front combination lamp RH terminal 6
- to rear combination lamp RH terminal 3.
Ground is supplied to the front combination lamp RH terminal 4 through grounds E17 and E43.
Ground is supplied to the rear combination lamp RH 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 right turn signal indicator lamp.
With power and input supplied, the BCM controls the flashing of the RH turn signal lamps.
