System Description
The Tiger 800 can be fitted with the accessory tyre pressure monitoring system (TPMS).
When fitted the tyre pressures shown on the instrument panel indicate the actual tyre pressure at the time of selecting the display. This may differ from the inflation pressure set when the tyres are cold because tyres become warmer during riding, causing the air in the tyre to expand and the pressure to increase. The cold inflation pressures specified by Triumph take account of this.
In addition, the system has an on-board diagnostic function. This ensures that, should a malfunction occur in the immobiliser system, a malfunction code is stored in the immobiliser/tyre pressure monitoring system (TPMS) control modules memory. This stored data can then be recovered using the Triumph diagnostic tool (see page 10-28).
Owners must only adjust tyre pressures when the tyres are cold using an accurate tyre pressure gauge and must not use the tyre pressure display on the instruments.
Warning: The tyre pressure monitoring system is not to be used as a tyre pressure gauge when adjusting the tyre pressures. For correct tyre pressures, always check the tyre pressures when the tyres are cold and using an accurate tyre pressure gauge.
Use of the TPMS system to set inflation pressures may lead to incorrect tyre pressures leading to loss of motorcycle control and an accident.
When fitting the TPMS, the installation flow-chart detailed in the Triumph diagnostic tool user guide must be followed.
System Components and Operation
- Instruments - Used to display. the tyre pressure value, the tyre symbol and the TPMS warning light.
- Immobiliser/TPMS control module -Receives the data from the tyre pressure sensors and sends the information to the instrument pack.
- Tyre pressure sensor - Situated inside the front and rear wheel. Each sensor has its own unique ID number and must be recorded in the spaces provided in the owner's handbook. These sensors measure the air pressure inside the tyre and transmit pressure data to the instruments. These sensors will not transmit the data until the motorcycle is travelling at a speed greater than 12 mph (20 km/h). Two dashes will be visible in the display area until the tyre pressure signal is received.
The wheel sensor is a sealed unit and must not be opened. The battery inside the sensor is not replaceable and a new sensor must be fitted when the battery voltage becomes too low.
Compliance
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
- This device may not cause harmful interference;
- This device must accept any interference received, including interference that may cause undesired operation.
Changes or modifications to the device could void the user's authority to operate the equipment.
Diagnostics
When a fault condition with the TPMS is detected, the red warning light in the instrument pack will illuminate and the tyre symbol will flash repeatedly.
The red warning light and flashing symbol will also occur if the TPMS has been enabled in the instrument pack but not in the immobiliser/TPMS control module. Before proceeding to the diagnostics, check that the motorcycle has wheel sensors fitted and that the option for the TPMS has been enabled in the immobiliser/TPMS control module.
Further Diagnosis
The tables that start on page 10-41, if used correctly, help to pinpoint a fault in the system once a diagnostic trouble code has been stored.
