Abstract (en)

[origin: WO8907815A1] Security apparatus (10) for immobilising a vehicle is disclosed in which a password or security number is entered into a keypad (14) and encoded by a tone encoder (15). The tone-encoded signal is transmitted along a wire (13) to an enclosure (25) in which a tone decoder (20) and a fuel solenoid valve (23) energized by the tone decoder (20) are encapsuled. The fuel solenoid valve (23) opens only when a security number which produces a tone-encoded signal to which the tone-decoder (20) will respond has been entered into the keyboard (14). The security apparatus (10) may be disabled in a service mode permitting the vehicle to be operated without providing a password to service personnel, and the mode in force is stored in non-volatile memory, allowing the power supply (17) to be disconnected for servicing purposes without the security apparatus (10) reverting to security mode.
