See illustration for fitting and quick release valve locations. (2) If air supply line is not constricted, quick release valve for affected wheel is faulty. NOTE If air line from quick release valve to affected wheel is partially obstructed, air line to wheel cannot escape back to quick release valve immediately after tire is pressurized causing wheel valve to remain partially open and tire to lose pressure. System will cycle again when low pressure is checked after 30 seconds. (1) Apply soapy water solution to CTIS fittings on outside of wheel. (2) Observe fittings for bubbles indicating leaks. (3) With wheel valve still connected to tire, disconnect wheel valve air supply line from hub at banjo bolt. (4) Place open end of air supply line in container of water. Look for air bubbles. (5) Persistent bubbles from air line indicate faulty wheel valve. (6) Connect wheel valve to hub at banjo bolt. SOAPY WATER LEAK TEST
