Quick Release Valves

• Serve as a remote air exhaust port
• Can be fitted with an external hose

to allow venting above deep-water

fording levels

Wheel Valves

• Normally closed design isolates

tires in the event of tire puncture

or hose failure

• Prevents tire pressure leak-down

automatically when parked

• No need for separate

shut-off valves

• Available options allow for integration

into aluminum wheels, eliminating

the need for external hoses

Pressure Switch

• Monitors pressure of vehicle’s

supply air tank

• Provides air system priority to

brakes, which suspends CTIS

operation in the event of low truck

air system pressure

Pneumatic Control Unit (PCU)

• Solenoid-controlled manifold

receives electrical commands from

the Electronic Control Unit (ECU)

• Controls wheel valves to inflate,

deflate, or measure tire pressures

by wheel position or axle groups

• Pressurizes the system only

during inflate/deflate cycles,

extending air seal life

Electronic Control Unit

(ECU) Option

• Microprocessor-based control center

receives driver input from the DDM

• Option to communicate to the drive-

train to optimize vehicle performance

• Supports industry standard

diagnostic tools

• Provides operator selections

for terrain and can be configured

to optimize tire pressures based

on axle loads

• Has ability to adjust engine speed,

transmission shifting, ABS, and

axle differential locks

• J1587 and J1939 data link

compatible

• Built-in self diagnostics

• Field programmable

Integrated Control Switch/

Driver Display Module (DDM)

• Compact rocker switches and

DDM provide operator interface

and are designed for instrument

panel mounting

• Supports three terrain and

two load selections

• Built-in diagnostic messaging
• Comes with a remote

mounted ECU
