4WD Control System

The 4WD control system consists of a 4WD switch, a vacuum switch, a vacuum tank, two vacuum switching
valves (VSV1 and VSV2) and air locking hub assemblies.
The 4WD controller controls locking or unlocking of the air locking hub according to operation of the transfer shift
control lever.
Vacuum generated in the intake manifold passes through the check valve and stored in the vacuum tank.
According to signals from the 4WD switch, the 4WD controller activates VSV1 (for unlocking) or VSV2 (for lock-
ing) to apply vacuum from the vacuum tank so that the front axle and the wheel hub are disengaged or engaged.
