As a general rule, statuses related to vehicle (wheel-end) health can be reset, whereas statuses indicating device operational failures cannot be reset and typically require device replacement.
An exception applies to when the device is mounted in the reversed position. This status does not indicate hardware failure, but incorrect installation. The issue can be resolved by reinstalling the device in the correct orientation.

Other common symptoms of device failure
In addition to the alarm states listed above, common symptoms of device failure may include:
- No data transmission from the device
- LED does not illuminate when activated with a magnet
- Damaged or broken metal baseplate
Reset options in the TraX Mobile App
The TraX mobile app provides two reset-related options, each serving a distinct purpose.
Option 1: Resetting an alarm
The Reset Sensor function:
- Clears all active alarms
- Deletes all stored temperature data
- Does not affect the device configuration
Not all alarm states are eligible for reset (see table above).
For detailed instructions, refer to section 6.12 – Resetting the Sensor in the User Manual.
Option 2: Removing and recommissioning a device
The Remove Sensor function:
- Disconnects the device from the SKF platform
- Does not change the device’s operational state
To fully reset and restore default configuration, the device must be recommissioned. However:
- The reset is temporary
- A new configuration is automatically applied after recommissioning
- It is not possible to perform a factory reset and leave the device unconfigured
