Troubleshooting

The Rabbit Box installation is very simple, but in some cars, generally classic ones, we encounter some problems that generate erroneous measurements or problems during an event.

Below we list the most common problems and their solutions:

It is recommended to use quality tablets and phones to avoid rare problems. Even so, it is advisable to restart the device before each rally day to free up memory that may be in use by other apps.

If you lose the connection between the tablet and the Rabbit Box, it may have a poor contact on the Box's power supply. A brief power interruption can cause the disconnection. There are also some settings that can help on Android devices:

• Reset Network Settings
  1. Settings > System > Advanced settings > Recovery options > Reset network settings. > Tap RESET SETTINGS.
• Disable Location Scanning via Wi-Fi and Bluetooth
  1. Settings > Location > Wi-Fi and Bluetooth scanning > Disable Wi-Fi network scanning and/or Bluetooth device scanning.
• Disable Open WiFi Network Notifications
  1. Settings > Wi-Fi > 3 dots upper right > Advanced settings > Disable Available network notification.

If you have problems with sensor readings, the first thing to do is identify whether they are reading too high or too low and on which sensor.

To start, let's check if there are false pulses generated by the car's electrical system:

• stop the magnet aligned with the sensor (LED on)
• check on the connections screen if the pulses count while stationary
• repeat the same with the other sensor.

If there are no false pulses while stationary, to verify the pulses you can go to a stage and follow these steps:

1. stop at the start
2. turn off the box and close the app (to reset the pulses)
3. turn on the box, reconnect the Wi-Fi and open the app (by doing this the app connects automatically when it opens)
4. drive to the end without exceeding 30 km/h
5. stop at the end and note the pulses (take a photo of the connections screen)
6. repeat the process to compare the measurements
7. if they don't match, send the two photos to our support group
8. if they match, repeat again but faster, for example at 60 km/h
9. if they don't match, send the three photos to our support group

We have seen many different cases that generate false pulses. The most common ways to avoid and discover where these pulses come from are:

1. Power the sensor and box directly from the battery
2. Use a shielded cable between the sensor and the box. The shield on both ends connected to ground.
3. Move the box and wiring to a location further away from sources of electrical pulses such as the coil, distributor, spark plug wires, relay box, etc.
4. Connect the box and sensors to an external battery to determine if it is an electrical problem or an electromagnetic pulse problem.
5. If none of this works, contact our support group.

If pulses are missing, we can suggest some common solutions:

• Verify that the sensor and magnet are properly aligned, even when turning
• Clean sensors and magnets of dirt and metal shavings
• Verify that when pulses are lost, the sensor and magnet are not too hot (60C maximum)
• Move the sensor 1 millimeter closer to the magnet
• If the wheel hub moves in turns, move the sensor away from the magnet (not common)
