Below are OBD2 Australia TPMS units installing/troubleshooting guides. Read on so we can help you!
Most of the time, issues with your TPMS unit can be sorted by GOING THROUGH the guides found here.
This is a self-help guide aimed to help you sort out issues with your TPMS unit. OBD2 Australia will redirect all TPMS installation/usage queries to this guide and will only entertain further queries IF all steps here have been executed thoroughly, and that video AND photo proof is provided showing and proving your claim of a ‘faulty’ TPMS unit. Please read this guide entirely for a better understanding on how to use and install this product. Note that these units require a technique to set up and just because it does not work due to an incorrect set-up does not mean it can be faulty.
CAR & 4WD SOLAR TYRE PRESSURE MONITORING SYSTEM – TPMSS4

Syncronising/pairing the sensors can sort out issues with your TPMSS4 unit if it is exhibiting the following:
1. The screen is flashing a particular sensor/s.
2. The pressure and temperature calibration is off.
3. Some sensors are missing.
4. If your display unit is frozen or not responding, press and hold the LEFT and RIGHT buttons to reset the unit, then perform the sensor pairing process. You can also try and charge it with a USB cable if it does not power on (the battery may have gone flat, so it’s unable to solar charge with a dead battery)
See our video guide below on how to properly synch/pair your TPMSS4 unit:
TPMSS4 PAIRING WHEEL SENSORS
There are times when synching may not work, and a sensor battery replacement is needed. Once you’ve changed the battery, please attempt to resynch as shown on the video above. Here is the guide on how to change the batteries on a sensor:

My TPMSS4/TPMSSS6 is not solar charging! What’s happening?
When solar energy is available and sufficient enough to power and charge the device, a solar icon and a battery-charging animation will show on your display. If you only see a solar icon and no battery animation, it means the available solar energy is not sufficient enough to charge and power the device simultaneously. It only has enough solar energy to power itself (which means it’s not using the battery for power). If both the solar icon and the battery animation are missing, it means that the device is using its battery for power. The device needs to have direct exposure to solar energy (directly facing the sun and not just exposed to light) in order for the solar panels to efficiently work (in both powering and charging the device). Tinted or frosted glass, or a shaded location on your dashboard will greatly affect this efficiency. We suggest charging via USB until full prior to first use, as solar charging on this device is only supplementary and should not be relied on as a primary source of power when the device is frequently used and not exposed to sufficient solar power.
What do I do if all the above steps do not work?
The device/unit may need to be replaced under warranty. For warranty replacements, we require video proof showing the problem. You can send the video to support@obd2australia.com.au or if it’s too large, you can upload to Youtube or Google Drive. Don’t forget to share us the link.
The video proof must show:
1. A hard reset on the display unit.
2. The correct synch process done on all sensors.
3. If the above does not work, please show new or working batteries being installed, then a hard reset then the correct synch process.
4. The video must also show any proof of the claim made.
Please bear in mind that these TPMS units require a step-by-step technique to set-up, and if done incorrectly the device will not function properly.
A non-working device does not necessarily mean its faulty. Sometimes the cause may be an incorrect set-up, therefore it is prudent it is executed properly with the aid of the guides above.
CARAVAN TRAILER SOLAR TYRE PRESSURE MONITORING SYSTEM – TPMSS6

Syncronising/pairing the sensors can sort out issues with your TPMSS6 unit if it is exhibiting the following:
1. The screen is flashing a particular sensor/s.
2. The pressue and temperature calibration is off.
3. Some sensors are missing.
4. If your display unit is frozen or not responding, press and hold the LEFT and RIGHT buttons to reset the unit, then perform the sensor pairing process.
