Four-Wheel Drive (4WD) Indicator Lamp: Description and Operation
SYSTEM OPERATION
On vehicles equipped with the optional four-wheel drive system, a four-wheel drive indicator lamp is located in the transfer case shift bezel on the
floor pan transmission tunnel. This lamp lights any time the transfer case is engaged in a four-wheel drive operating mode.
When the ignition switch is in the On position, battery voltage is supplied to one side of the indicator lamp bulb. A normally-open, plunger-type,
four-wheel drive switch in the transfer case is hard-wired in series between the other side of the indicator lamp bulb and ground.
When the transfer case is shifted into the 4L or 4H positions, the plunger of the four-wheel drive switch is moved, closing the switch and providing
a path to ground. This causes the four-wheel drive indicator lamp bulb to light.
