SEO CANi IMMOBILIZER – INSTALLER MANUAL
The SEO CANi is a digital immobilizer that protects the vehicle through disabling its mobility
by sending the appropriate commands to the cars e.g. ECU and/or BCM controllers. The code
blocking can be done by both CAN BUSes or LIN BUS (see the appropriate installation
diagrams). It’s also possible to break an electric circuit using an analogue cut with a solid-state
control output (1A load). The immobilizer is disarmed by entering a previously set code using
the existing buttons in the car (PIN code).
The PIN code can be reset by setting the 5-digit program number for the vehicle again.
The CANi immobilizer can be connected to an external car alarm system as an additional layer
of security. It can also provide extra security in cars with keyless entry. If the device is connected
to an external system, such as a GPS/GSM tracker, remote immobilisation from this device will
take priority over the PIN code immobilisation from the CANi. Unlike other car security
systems the CANi can be installed on electric cars, and can be used in car sharing.
The PIN code is formed from a combination of the cars existing buttons. The number of
combinations of the PIN code (W) is given by
, where n is the number of supported
buttons (≤30) and k is the number of buttons in the PIN code (≤15) (including repetitions). If
the number of supported buttons for a particular vehicle does not permit at least 10,000
combinations (e.g. Renault cars) (see the formula above), use the SEO CANblu instead of
SEO CANi as the car security system to maintain security.
The CANi immobilizer can be disarmed by the PIN code. When the immobilizer is armed, there
are few possible ways of protecting the vehicle from theft (depending on the car model, engine
type, and fittings):
a) Preventing the engine from starting
b) Engine shutdown – it’s possible to start the engine, but it stops when the thief attempts
to drive the vehicle away
• For vehicles with automatic transmission, the engine stops when the gear stick
is moved from the P position,
• For vehicles with manual transmission, the engine stops when the clutch pedal
is pressed.
c) Preventing the vehicle from moving – the SEO CANi immobilizer allows you to start
the engine, but you are not able to drive away. The engine is not shot down,
d) Preventing the ignition from being switched on – the SEO CANi immobilizer does not
allow you to switch on the ignition.
The complete database of supported vehicles and associated connection diagrams can be
found at www.can24.pro. You will need to log in. The connection diagram shows the program
number specific to that car as well as the buttons available for entering the PIN code and the
dashboard indicator. The immobilizer’s microcontroller may include programs for all
declared vehicles.
