2-24. CENTRAL TIRE INFLATION SYSTEM (CTIS) (CONT).
The CTIS rotary selector switch setting should always
correspond to the lighted setting. If the light and switch
positions do not match, the operator must take steps to correct
the situation. Failure to comply may result in damage to
equipment.
(a)
A continuous green light (5) indicates the CTIS and driveline lockup
are both in proper operating mode and CTIS pressure
check/adjustment cycle has been completed.
(b)
A flashing green light (5) indicates the CTIS is in the process of
checking/adjusting the tire pressure.
The CTIS increases tire inflation pressure when truck speed
exceeds the allowable speed for each setting. When an
increase in speed is required, maintain the lower speed until
the tires are re-inflated to the correct pressure. Failure to
comply may result in damage to equipment.
(c)
A rapidly flashing green light (5) indicates the CTIS rotary selector
switch and tire pressure do not match and requires the operator to take
corrective action.
(d)
The amber overspeed light (6) begins to flash when an overspeed
condition has been present for one minute and continues to flash along
with the green light until the new CTIS setting is reached.
