TractionAir ECU Operation and Functionality
The ECU has four variable pressure adjustments, factory pre-set to your fleet’s
requirements. Below is a common example that explains the functionality.
The LEDs indicate the setting selected by the operator.

32psi
Whenever a pressure setting is changed, the LED button light will flash, then go
to a solid state once pressure is achieved. The system checks itself every 10
seconds. If after 10 seconds the pressure is constant, the LED will light up as a
solid light, indicating the pressure setting is achieved.
Small Leaks
Should the driver find that the system is achieving pressure but the Air LED for
the selected pressure is not changing to a solid state, there is a small air leak.
The system will keep up with the majority of small air leaks, however the driver
will need to monitor the situation and have the leak attended to when practical.
Note: Pressure changes in the field. The changing of pressures pre-selected by
the installer should not be made until recommendations have been obtained from
your tyre supplier. The wrong pressure setting at speed may damage the tyres.
Major Loss of Air Pressure
If there is an unselected pressure drop from a previously selected setting, the
control system will try to restore the pressure. If the pressure keeps dropping,
the system will continue to feed the leak, an audible alarm will sound which will
alert the driver to the pressure readings on the ECU: “The ECU reads the tyre
pressure in real time”. After 20 seconds of continually dropping air pressure, the
following message is displayed-
“Leaks or NO AIR”
