CTIS Troubleshooting (Contd)

MALFUNCTION

TEST OR INSPECTION

CORRECTIVE ACTION

Step 2. Remove one air tube from tee at connection on rear axle to produce a large air leak.

Step 3. Start engine and run at 1500-1700 RPM and select cross-country setting.

Step 4. When FLAT appears on LCD display, hold cross-country button for three seconds to

initiate RUN FLAT mode.

Step 5. Install air tube on tee connection on rear axle.

NOTE

The display will indicate RUN FLAT ACTIVE and the

vehicle air supply will run continuously. The system will

attempt to pressurize to the set points, which will hold

pressure in the air lines.

Step 6. Lightly spray air lines and fittings with the liquid leak detector solution. Bubbling

indicates leakage. Tighten loose fittings.

Step 7. Return engine to idle speed and turn ignition OFF after inspection is completed.

END OF TESTING!

CTIS INFLATES TIRE(S) SLOWLY

Step 1. Check for punctured or damaged tires. Repair tire(s) (WP 0175 00) or replace tire(s)

WARNING

Eyeshields must be worn when releasing compressed air.

Failure to do this may result in injury to personnel.

Do not disconnect air lines before draining air reservoirs.

Small parts under pressure may shoot out with high velocity,

causing injury to personnel.

Step 2. Check compressed air system (WP 0013 00).

Step 3. Replace coalescing filter if oil is observed in wheel valve (WP 0281 00).

Step 4. Check air flow at outlet end of wheel valve filter. Pressure should be between 13-45 psi

(90-310 kPa). Replace wheel valve filter (WP 0176 00), if necessary.

Step 5. Perform test 3.
