Immobiliser and Keyless Ignition System
System Description
This model is fitted with an electronic immobiliser and keyless ignition system to help
protect it against theft. The immobiliser and keyless ignition system are incorporated in
the keyless ECM. The keyless ECM has to be paired with the engine ECM and the ignition
keys which each contain a transponder chip. If all the components are correctly paired,
the immobiliser will allow the engine to start. These components can only be paired
using the Triumph diagnostic tool.
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 keyless
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 when
requested by the keyless ECM, providing the key is in range of the LF antenna (within
one meter/three feet for smart keys, within 50 mm for passive keys).
• Low Frequency (LF) Antenna - there are two LF Antenna on this model. One is
situated on the left hand rear mudguard under tray. two moulded in pips in the left
hand undertray indicate the location of the LF antenna. The second is under the
flyscreen on the right hand side. The transponder chip in the ignition key is activated
when it is in range of the LF antenna. The signal from the chip is interpreted by the
keyless ECM.
• Keyless ECM - situated at the rear of the airbox. This control module communicates
with the transponder chip in the key via the LF antenna, and with the engine ECM.
The keyless ECM will only allow the motorcycle's electronic systems to turn on and
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
