(2H) Operation

When the ATCM is in (2H), power is delivered to the rear wheels only. This mode is appropriate for normal on-road driving on dry pavement and provides the best fuel economy. Torque is passed through the transfer case to the rear driveshaft at a 1:1 ratio. In (2H):

• The ATCM sends a (2H) mode status to the AWD module via the GWM.
• The transfer case clutch is at or below the kiss point.
• The reduction sleeve connects the input shaft and output shaft
• (2H) will momentarily be displayed in the message center at key up and after a 4WD to (2H) shift.
