Operational Instructions

Operational Instructions

Three Basic Operation Modes:

Settings:

Manual-Mode

Auto-Mode

Option-Mode

The system displays the actual airbag pressures, and the user controls the pressure manually.

The system displays the pressure settings and automatically maintains the prescribed airbag
pressures.

The user can examine and change all option settings.

The system keeps the user’s option settings in non-volatile memory so that they will be maintained each time the
system is powered up.  On power-up, the options settings are read and acted on appropriately.

Ride Ht

Auto

Leak

The system will immediately restore the airbag pressures to the saved setting values on power-up.

When ride-height is selected (either through “Ride Ht” option setting or user selection during
operation), the system will automatically maintain the airbag pressure at the current settings.
The system will display detected leaks in any of the airbag circuits.  A leak is shown by the letter
“L” next to the pressure reading.

Volts

Bright

The display will show the system voltage.  If both “Volts” and “Tank” are enabled, the display
will alternate between them every 20 seconds.

The display will show the current tank pressure.  If both “Volts” and “Tank” are enabled, the
display will alternate between them every 20 seconds.

Controls the display intensity.  If the display intensity is changed while it is dimmed automatically by
the vehicle lights connection, it will remain at the selected brightness until the next time the vehicle
lights are turned on.

Tank

The system will perform pressure regulation on the airbags sequentially (left front, right front,
left rear, right rear).  If not enabled, the system will simultaneously adjust all airbag pressures.

Seq

To use the TUNE function, the tune option must be set to ON and it must be displayed when
the ride height button is used to exit option-mode.  The TUNE function will test the response of
the system by exercising the airbags individually.  The results are stored by the system for use
in accurately controlling airbag pressures.  The TUNE function must only be accomplished in a
stationary vehicle on level ground.
