Body Controller: Description and Operation
Chassis System (Automatic Air Load Leveling)
CHASSIS SYSTEM (Automatic Air Load Leveling)
The major components of this system are the Automatic Air Load Leveling Module (Control Module), the Right Air
Shock which includes the height sensor, the Compressor Assembly which includes the air exhaust solenoid, and the Compressor Relay.
The Control Module is a device that controls the ground circuits for the compressor relay and the air exhaust solenoid. A microprocessor within the
module controls the compressor pump operation from 140 seconds to 160 seconds. This prevents damage to a normal system.
Caution should be observed while manually operating the compressor during test procedures to avoid damage from prolonged and excessive
operation of the compressor.
