Range Status Indication

The range change selection switch has a LED, this LED operates in three ways:

• The LED illuminates when the twin speed transfer case is in low range.
• The LED is switched OFF when the twin speed transfer case is in the high range.
• The LED is flashing when range change operation is in progress.

There is a message displayed in the IPC  message center, which can also inform the driver of any faults with the twin speed transfer case.

The low range status warning indicator in the IPC  has the following logic:

• The warning indicator illuminates when the twin speed transfer case is in low range.
• The warning indicator is switched off when the twin speed transfer case is in high range.
• The warning indicator is flashing when range change is pending or range change is in progress.
