GENERAL

The Central Tire Inflation System (CTIS) allows the operator to adjust tire pressures for

current vehicle operating conditions. This work package provides the data and procedures

for operating the CTIS. Items covered include Normal CTIS Operation, Operation In

Emergency (EMER) Mode, Operation In RUN FLAT, Operation With Four CTIS ECU Mode

Lights Flashing; and Resetting the CTIS.

NORMAL CTIS OPERATION

Start engine (WP 0016 00).

NOTE

If vehicle is stopped when CTIS mode is changed, it may be necessary to

increase engine speed to provide adequate air supply to tires.

CTIS will automatically shut off when air system pressure drops below 74 psi

(510 kPa), or when CTIS malfunction occurs.

Slowly press down on accelerator pedal (1) if FRONT BRAKE AIR pressure gage (2)

and REAR BRAKE AIR pressure gage (3) read less than 100 psi (690 kPa).
