Troubleshoot Sensor and Relay
If a tyre sensor can not be located:
1. Troubleshoot the sensor and valve stem pin. (See 5.2 Troubleshooting Sensor and Valve Stem)
2. To troubleshoot a particular wheel location, fix LCD Display Monitor to the wheel location (fig.2.4.1)
3. Take the LCD Display Monitor in hand to the wheel location where the sensor is attached. Briefly
loosen the sensor to release some air (you should hear a hiss) and then re-mount sensor, the sensor
will transmit 4 signals to the monitor in 4 second intervals. You have 12 seconds to return to the LCD
Display Mount position before the sensor returns to normal working mode (i.e. normal 8 minutes
signal transmission cycle).
4. If you determine that the sensor is working properly and you do not receive a signal from the relay, the
position of the relay maybe affecting the wireless reception. Please re-install and change the location
of the relay.
