Troubleshooting

Air Pressure Check

Note that the Tire Pressure Control System is not continuously

pressurized; pressure checks occur on a periodic basis. During tire

pressure checks, the system delivers compressed air to each channel

for approxi mately two seconds while monitoring the pressure in that

channel.

Code Description

Code 1OP! displays if a channel fails to conﬁrm tire pressure. Following

an inﬂate or deﬂate of a given channel, the Tire Pressure Control System

will return to that channel to conﬁrm, or “double-check” the new

pressure. If the pressure has dropped, the system will reinﬂate, and then

reconﬁrm that channel. After multiple conﬁrmation attempts, the system

will log a 1OP! and the channel will become inoperative.

A conﬁrmation failure can be caused by:

• Damaged or leaking tire

• Leaking air line between the wheel valve and tire

• Wheel valve failure.

To correctly diagnose the faulty component, connect the Diagnostic

Tool (see Section 5 for test equipment and descriptions) and follow the

procedure in the 10P! troubleshooting tree.

See “Troubleshooting Tips” on page 20 for general guidelines on system

diagnostics.

Code: 10P!

Type: Tire Leak (Conrm)
