Putting into operation 4
Safety functions
• The immobilizer remains enabled for 15 minutes and does not accept
any valid keys if more than 5 keys with different invalid codes are
inserted and turned in the ignition lock within 1 minute.
• This function avoids ‘finding’ the correct key by chance by trying
different keys.
• Valid keys are accepted only after 15 minutes and after the position (0)
of the ignition lock has been detected. This avoids testing keys without
actuating the mechanical ignition lock, for example by moving the
ignition lock to position (2) by force.
• Interruptions of the supply line or other control lines do not disable the
immobilizer or delete data (for example data codes).
• All important data is saved in a non-volatile memory.
