Troubleshooting
Code Description
Code 9P! displays when system pressure is dropping while in inflate
mode. The air leak that is causing 9P! is large enough to more than
offset the pressure input, and should be clearly audible.
The air leak can be located either before or after the wheel valve
location. The components located before the wheel valve that may
cause a code 9P! include:
• Leaking control lines
• Restricted wheel valve exhaust port
• Leaking wheel air seals
Components located after the wheel valve that may cause a code 9P!
include:
• Tire damage
• Rim leaks
• Leaking air lines
• Faulty wheel valve.
To correctly diagnose the faulty component, connect the Diagnostic
Tool (see Section 5 for test equipment and descriptions) and follow the
procedure in the 9P! troubleshooting tree.
See “Troubleshooting Tips” on page 20 for general guidelines on system
diagnostics.
