TPMS Overview

Enabling or disabling TPMS monitoring in the navigation app can be performed in the TPMS settings menu (Main Menu -> System & Setting Menu)

The user can easily select 16 PSI (sand) or 28 PSI (sealed roads) for the low pressure alarm.

Selecting on a blue question mark provides the user with an explanation of the setting.

Unused sensors must be disabled, e.g when only two sensors are used on a motorcycle.

Selecting the "TPMS Configuration" icon allows the use to bind the wheel sensors and set other TPMS parameters.

The the owner can assign a unique vehicle ID the ONIS which will be used in the TPMS logs and saved images. 

Wheel sensor binding can be performed from the TPMS configuration app. 

The existing wheel sensor ID's are displayed on the top menu and when a new sensor is bound, the new ID will be displayed in the blue circle.

We recommend binding a wheel sensor using the automatic method which is easily performed by setting the app to scan for the selected sensor and then unscrewing and re-screwing the sensor on the valve stem to trigger the bluetooth communication.

There is a button selection that describes how to bind the sensor labeled "Sensor Binding Instructions" at the bottom of the screen.

The Outback Navigation Information System (ONIS) uses PSI as the default pressure unit, and degrees C for temperature (these units MUST not be changed).

The pressure, temperature and sensor battery threshold limits can be altered using the slider bars.

We recommend that the wheel sensor battery electricity is not set lower than 15%.

User help for the settings and wheel sensor binding is available using the selections on the screen.

The Outback Navigation Information System (ONIS) is dedicated to a vehicle, unlike a smartphone which remains with the person.

The ONIS is a personal navigation device (PND) and under state laws a PND can be legally operated whilst driving (users should check their own jurisdictions), unlike a smartphone.

The ONIS utilises generic BLE wheel sensors (kit of 4) providing flexibility as spares, as the individual sensors can be configured to any vehicle with the only proviso being the correct wheel allocation.

Note: OziExplorer image shown. This function is also available when the iGO app is running.

A TPMS BLE (Bluetooth low energy) system is integrated into the Outback Navigation Information System (ONIS) which runs in the background whilst the OziExplorer navigation app is running.

If there is a TPMS alarm condition (e.g. low tyre pressure):

• the TPMS app has the highest priority

• a highly visible TPMS screen will be displayed

•  an audio alert warning will sound at maximum volume

• the OziExplorer app will close automatically

• a TPMS page will display which tyre is in alarm

• the system will capture and save the TPMS alarm screen 

• the system will log the TPMS alarm details

These automated features allow the driver to focus and manoeuvre the vehicle to a safe location without having to perform any user input (other than the audio mute, if desired ) until the vehicle is parked. 

For driving in terrains such as beach or sand, the driver may reduce the tyre pressures to suit the driving conditions.

When reducing tyre pressures, the TPMS "Low Pressure Alarm Setpoint" will also need to be reduced or the TPMS app will alarm and shutdown the navigation app.

The Outback Navigation Information System (ONIS) has two features that warn the driver if they still have the "Low Pressure Alarm Setpoint" set below 25 PSI or 20 PSI:

• when the navigation app is started, a message will display the current setting and warn if below 25 PSI

• whilst the navigation app is running, a continual warning message will be displayed with an associated audio alert if the "Low Pressure Alarm Setpoint" is set below 20 PSI and the vehicle speed exceeds 60 km/h.

The ONIS incorporates a wheel sensor health function. If the ONIS receives valid Bluetooth communication from a wheel sensor within a 24 hour rolling window, the sensor is deemed functional by the ONIS system, however routine testing of the wheel sensors is recommended by GPSIS. 

Note: OziExplorer image shown. This function is also available when the iGO app is running.

If there is a TPMS alarm, a saved screen image (see below) will be captured and a log entry added to the "TPMS Alarm Log" (see above).

If there is a TPMS test condition (e.g. low tyre pressure whilst testing the wheel sensors), a saved screen image (see below) will be captured and a log entry added to the "TPMS Test Log" (see above).

If there is an existing TPMS alarm when starting the navigation app, a message will be displayed.

The user has 3 minutes to check / test the sensor before the navigation app is closed.

If the sensor is tested and transitions to the healthy state, the navigation app startup sequence continues automatically.

A TPMS lithium battery warning messages will be displayed when starting the navigation app.

The user is also presented with the "quick set" option of selecting 16 PSI or 28 PSI as the low pressure alarm setpoint.

The user has 5 seconds to make this change and the selected setting will remain the default, until changed again by the user.

Values other than 16 or 28 PSI, can be easily be set as the default in the "System & Settings" App, 

In the event of a of a TPMS alarm, a saved screen image will be captured.

The TPMS alarm record system retains the 30 most recent TPMS Alarms.

When a TPMS test is performed, a saved screen image will be captured".

The TPMS test record system retains the 30 most recent TPMS Tests.
