CENTRAL TIRE INFLATION SYSTEM (CTIS) REPEATEDLY RESUMES CYCLING 30 SECONDS AFTER INDICATOR LIGHTS STOP FLASHING (cont)

TM 9-2320-366-20-3

WARNING

Wear appropriate eye protection

when working under vehicle and

around CTIS system due to the

possibility of falling and/or

blown debris. Failure to comply

may result in injury to personnel.

NOTE

CTIS ECU checks tire pressure 30

seconds after completing a

pressure change sequence. If tire

pressures are the same, system

reverts to checking pressure every

15 minutes. If tires are losing

pressure, ECU inflates tires and

checks pressure again in 30

seconds. If CTIS has to repeat this

process more than 10 times, ECU

will display four flashing lights.

(1) Measure and record the tire pressure of

each tire (TM 9-2320-366-10-1).

(2) If front tire(s) have lower pressure than the

rest, kneeling valve, tire or CTIS wheel valve

is faulty.

(3) If rear tire(s) have lower pressure than the

rest, tire or CTIS wheel valve is faulty.
