High/Low Range Change Light Emitting Diode

The high/low range change Light Emitting Diode (LED) is connected to the Terrain Response switchpack (TR). The TCCM  sends the range change state by the FlexRay to the BCM  /GWM  . The BCM  /GWM  transmits this signal through the High Speed (HS) CAN  chassis systems but to the TR  . The TR  illuminates the high/low range change LED depending on the range change states from the TCCM  .

When the transfer case is in high range, the LED is not illuminated. When range change is in progress, the LED flashes ON until the new range statu is achieved.
