Service Codes

Group: 4P! (Codes 23, 24, 25)

Type: Channel Between Modes

Code Description

Group 4P! displays if any channel inflates or deflates too

slowly as shown below:

• 23 - Front Channel

• 24 - Rear Channel

• 25 - Trailer Channel

The maximum allotted time for each channel is 40 minutes for

an inflate, or 20

minutes for a deflate. The most likely cause is

a faulty compressor or similar problem resulting in

inadequate air supply to the T

ire Pressure Control System.

If the system air supply is function

ing properly, code group

4P! may indicate that a leak or restriction exists in an air

passage. The components that may contain a

restricted or

leaking air passage include:

• Wheel valve air filters.

• Pneumatic Control Unit (PCU)

vent port restriction.

• Air supply lines.

• Wheel valve exhaust port (deflate mode only).

To identify the root cause of the problem, connect the

diagnostic tool (see Diagnostics Section for test equipment

and descriptions)

and follow the procedure in the

4P! Troubleshooting Tree.

See "Troubleshooting Tips" for general guidelines

on system

diagnostics.
