The Engine Immobiliser - Immobilises the Engine !
It is an electronic Security device to help prevent theft of the motorcycle.
The Ignition Key containers a coded Transponder ( Computer chip ), which is "paired" ( programmed ) to the motorcycle.
The code ( Maximum of four ) is stored within the Immobiliser Control Module.
When an Ignition key is used, its Transponder Code is read by the Control Module,
( there is a coil antenna sensor built around the Ignition Switch ) and if the Code is correct,
the Ignition Circuit is activated allowing the engine to be started.
If ( one of ) the correct Transponders are not present and recognised by the Control Module,
e.g. because of not being "paired", or there is a fault, then the motorcyle cannot be started.
The actual Control Module is a combined Immobiliser and Tyre Pressure Monitoring System ( TPMS ) Control Module,
attached to the front subframe underneath the left mirror mounting.
The instrument panel assembly has a red LED which flashes to confirm the system is active when the Ignition has been turned off.
The LED will flash on and off for 24 hours, and will then shut off to preserve battery capacity,
although the Immobiliser system remains active.If a Triumph alarm system has been installed, then the LED may have different functions -
consult the alarm documentation for details.
In the event of a fault the red LED will remain ON, and any fault code will be stored n the Control Module,
and can then be read by Triumph dealer diagnostic equipment.
