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 Wk = nk, 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):
1. Preventing the engine from starting. 2. 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.
3. 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. 4. 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.
The step-by-step installation procedure
- connect the GROUND cable,
- then connect + 12V,
-
set a 5-digit program number dedicated to the car, using the PCB button and LED (see: setting the 5-digit program number); the program number can also be set using the 0351 interface. connect CAN L,
-
connect CAN H, in case of SEO CANblu P/N 3977xxxx connect also LIN1,
-
set the PIN code to be used when disarming the immobilizer (optional).
ATTENTION! Do not use the power supply from the OBD port. To increase security you could consider removing the CAN wires from the OBD connector (or connect these wires with the use of a relay and PIN9 of SEO device) in you choose to do this the garage/workshop should be informed at every visit.
The SEO CANi immobilizer can only communicate with the CAN bus when it's properly connected and transmission has been established, i.e. the LED on the main unit flashes. Always connect all wires indicated in the connection diagram. Disconnecting the device or just cutting the + 12 V power wire will prevent the device from working effectively. The user should be informed where the SEO CAN main unit has been mounted. By default, the device is set to the neutral program number 11120.
ATTENTION! After setting the program number and installing the device, the immobilizer will not block the car, if the PIN code has not been set. The the PIN code must be set for the immobilizer to block the car
The SEO CANi immobilizer can work with any AVL (Automatic Vehicle Location) device equipped with an active output. Connecting the device to a GPS/GSM tracker enables remote immobilization. An external constant GND on PIN6 in SEO CAN P/N 2050xxxx or PIN2 in SEO CANi P/N 3876xxxx of the 10-PIN immobilizer connector immobilizes the vehicle whether or not the immobilizer has previously been disarmed with the PIN code. This method of immobilization works even in service mode. If PIN6 is grounded while the vehicle is in motion the immobilization will occur after the vehicle has stopped and the ignition is switched off.
A version of the SEO CANi that is used only with GPS/GSM trackers (without the option of using PIN code) is also available.
The immobilizer can be disarmed independently of opening the car using the original remote. So that the immobilizer cannot be disarmed when the car is opened by door lock cylinder (using the key), i.e. so that it can be disarmed only after opening the car with the original remote or keyless, enter the program number for the selected vehicle and then enter program 23986. Applies to devices with software date 2022-02-11 or newer.
Setting the 5-digit Program number dedicated for a particular vehicle
The main unit's LED and switch (the one located closer to the connector) allows you to enter the correct program number for the vehicle. The program number can be found on the list of vehicles supported by SEO CANi immobilizer and on connection diagram dedicated to the vehicle.
Press and hold the button until the LED starts to flash, then release the button; the LED will start counting (from 1 to 9) to indicate the first digit of the five digit program number. To program the first digit press and hold the button after the correct number of flashes until the LED starts to flash again, then release the button.
Program the next digits of the program number in the same way. The LED will flash 10 times after programming is completed successfully. Then the main unit will then restart, which is signaled by a double flash of the LED.
Checking the program number: Press the button briefly, the LED of the main unit will blink out the 5-digit pre-set program number and then the connection status of the 6 connected CAN BUSes (even if the device is connected only to 2 CAN BUSes).
The number of flashes indicates the status of 6 CAN BUSes: 1 flash - CAN is connected or has already been connected but does not receive any data at the moment (i.e. the CAN BUS is in sleep mode); 2 flashes - CAN is connected and is receiving data at the moment; 3 flashes - CAN is disconnected, but requires connection; 4 flashes - CAN is not supported, no connection required.
Setting the PIN code used to disarm the immobilizer
The list of buttons available for use for the PIN code in a particular vehicle can be found on respective connections diagrams and on the list of vehicles supported by SEO CANi immobilizer.
Before programing a new PIN, disarm the immobilizer by entering the existing PIN code or using paired ID transmitter (the initial programming, during installation, does not require disarming). To enter programming mode press the service button 10 times with the ignition on and enter the new PIN code of 1 to 15 supported buttons. Turn the ignition off to confirm the new PIN code (this will be confirmed by one flash of the dashboard indicator). If vou do not switch the ignition off within 10 seconds of entering the last button, the new PIN code will be discarded.
The light indicating the status of the immobilizer is shown on the list of supported vehicles for the SEO CANi immobilizer in the vehicle name column. The installer can enter the programming mode, by entering the program number 11999 while the ignition is on - then enter the PIN code as above.
The pin code must consist of at least 2 different buttons. (applies from the software date 2023-01-12)
Updating the software with the 0350 programmer device
Connect the SEO CANblu device through 0351 programmer device to the computer to update the immobilizer database. For this purpose along with the programmer device we also provide the PC software necessary for the update. The programmer device can update the database of supported vehicles.
RHD cars
If, in the car in which you install the immobilizer, it is armed not when the driver's door is opened, but when the passenger door is opened, you can "swap" the door.
To do this, enter the program number for the particular car, then enter program number 11981. The return to the standard door recognition occurs when the program number for the particular car is set.
If the device was installed before 2020-11-04 and later updated, but the program number for a particular car has not been re-set, the immobilizer will be armed when the right door is opened. To "swap" the doors, set the program number for the selected car again.
