  • Description

The SEO CANi device is a digital immobilizer which protects the vehicle digitally blocking the drive-away by sending appropriate commands to the ECU and/or BCM drivers of the car. The code blocking can be done by both CAN BUSes (according to dedicated installation schemes). It’s also possible to cut an electric circuit in analog way using the existing electronic control output with a load of 1A. The immobilizer can be disarmed by entering the previously-set vehicle’s buttons combination (PIN code). Connecting the device to an external system, like a GPS/GSM tracker enables a priority of remote immobilization. The immobilizer can also be used in a car-sharing or connected to the car alarm system as an additional blockade. SEO CANi is also an extra protection in addition to the original keyless system. The device, unlike other car security systems, protects electric cars as well.

            PIN code is a combination of existing car buttons, where k ≤ 15 expressive variation with repetitions from n ≤ 30 element set buttons supported by CAN BUS. If the number of supported buttons declared on a particular connection diagram does not allow to fulfill the number of 10,000 combinations, with maintaining the customer’s comfort, use SEO CANblu as a car security, instead of SEO CANi (it applies to, for example, Renault cars).

 

 

The authorization can be done using the ID transmitter, PIN code or smartphone. When the immobilizer has not been authorized, there are two possibilities of its reaction (depending on the car model, engine type, and the equipment):

  1. Locking engine start-up – SEO CANi immobilizer will prevent engine start-up
  2. Blocking driving away – it’s possible to start the engine, but it will be shut down when trying to drive away
    • In the case of an automatic transmission, the engine will be shut down when the position of the shift stick will be changed from the P position,
    • In the case of a manual transmission, the engine will be shut down when the clutch pedal will be pressed.

 

Immobilizer’s microcontroller may include Programs for all declared vehicles. On particular connection diagrams, Program numbers dedicated to specific cars are shown. The switches to use for PIN code in specific vehicle are also marked and dashboard’s indicator was shown as well.
