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 is 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..
