Immobilizer functionality
GND will appear on PIN 9/15 when the correct PIN code has been entered.
The PIN code is a combination of any buttons available in a particular vehicle (supported
buttons are listed on the connection diagram for the respective vehicle). 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)
Disarming the immobilizer – while the ignition is ON, press the previously set buttons’
combination. Single blink of the dashboard indicator will confirm disarming of the immobilizer.
The time between pressing consecutive buttons must be shorter than 5 sec; in some vehicles
this time must be longer than 0.4 sec.
Arming the immobilizer – automatic after switching the ignition OFF and opening the driver’s
door (2 blinks of the dashboard indicator)
Attention!
After 50 unsuccessful attempts to enter the PIN code, the device will not unlock for 30 seconds
even after the correct PIN code has been entered.
The attempt is treated as unsuccessful when you make a mistake in entering the code. The
device then waits for the correct sequence to be entered from the beginning.
One unsuccessful attempt is when you start entering the PIN code (by pressing one or more consecutive correct
buttons) interrupted by pressing invalid button.
Service mode
To switch the service mode ON using only the PIN code, turn the ignition ON, disarm the
immobilizer by entering the previously set PIN code and holding the last programmed button
for 10 seconds. If you successfully managed to enable the service mode, the indicator on the
dashboard will blink 5 times.
To switch the service mode OFF, just enter the PIN code holding the last button until the
dashboard indicator blinks once.
Attention – switching the service mode ON/OFF when the immobilizer blocks switching the
ignition ON – with the ignition OFF disarm the immobilizer by entering the previously set PIN
code, switch the ignition ON and enter again the previously set PIN code holding the last
programmed button for 10 seconds. If you successfully managed to enable the service mode,
the indicator on the dashboard will blink 5 times.
If you want to switch the service mode off, just repeat the above procedure.
WA R N I N G – in the service mode the dashboard indicator does not indicate that the service
mode is active and the car is not protected – the car owner, after picking the vehicle up
from servicing, should immediately switch the service mode OFF. During normal
operation, the SEO CANpro indicates (by the dashboard indicator light) whether it has
been armed or disarmed.
