Four Wheel Drive Indicator Lamp: Description and Operation
4x4/Low Range Indicators with Lever-Operated Transfer Case
The 4x4/low range indicator lamp circuit consists of two lamps located on the instrument cluster and a switch located in the transfer case. One lamp
indicates when the vehicle is in the 4-wheel drive position (4H) and one lamp indicates when the vehicle is in the 4-wheel drive low range position
(4L).
When the 4-wheel drive is engaged, the switch closes a first contact and the 4x4 lamp illuminates. When the low range is engaged, the switch closes a
second contact and the low range bulb illuminates at the same time as the 4x4 lamp illuminates.
4x4/Low Range Indicators with Electronic Shift Transfer Case
The electronic shift control, located on instrument panel, consists of a rotary type switch. The 4x4 switch selects either the 2-wheel drive or the
4-wheel drive position. The instrument cluster indicator will illuminate when the 4-wheel drive position is engaged. The low range position is used to
select and indicate 4x4 low range. The light will illuminate when a signal is received from the Generic Electronic Module (GEM) indicating low range
is engaged.
The generic electronic module controls the operation of the transfer case in response to inputs to the rotary switch controlled by the vehicle operator.
