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 chassis ECM memory. This stored data can then be recovered using the Triumph diagnostic tool (see System Diagnostics).
System components and operation
- Transponder chip - situated inside the ignition key. The chip is activated by the antenna coil when the ignition switch is turned to the ON position.
- Antenna coil - situated around the ignition switch. When the ignition switch is turned to the ON position, and the transponder chip is activated, the signal from the chip is sent to the immobiliser/TPMS control module.
- Immobilise/TPMS Control Module - situated inside the airbox. This control module communicates with the transponder chip in the key and the engine ECM and will only allow the engine to start if a matching signal is received.
- Alarm/immobiliser warning indicator light - situated in the instrument pack. The light will flash on and off for 24 hours to show that the engine immobiliser is on. When the ignition switch is turned to the ON position the immobiliser and the indicator light will be off. If the indicator light remains on it indicates that the immobiliser has a malfunction that requires investigation. If an accessory alarm is fitted, the immobiliser indicator light will only illuminate when the conditions described in the accessory alarm instructions are met.
Keys
When the motorcycle is delivered from the factory it is supplied with two keys. Keys can be deleted or added to the immobiliser system using the Triumph diagnostic tool. A maximum of four keys can be added to the system.
To ensure the immobiliser system functions correctly note the following:
- Do not put any magnetic materials on the same key ring as the motorcycle key.
- Do not put any other ignition key with a transponder chip fitted near the motorcycle key when in use.
- Do not modify the immobiliser system.
- Do not submerge the key in water or any other fluid.
- Do not drop or strike the key against hard material.
Diagnostics
To fully diagnose the immobiliser system it is necessary to check for fault codes in the immobiliser control module using the Triumph diagnostic tool (see System Diagnostics).
Further diagnosis
The diagnostic trouble code tables, if used correctly, help to pinpoint a fault in the system once a diagnostic trouble code has been stored (see System Diagnostics).
