The status is stored in EEPROM. In case of not plausible data from this circuit the EMS cannot check
the status and EMS sends 00.
b. Learnt
At least one Key has been taught successfully.
c. Virgin
This is the status at the end of EMS production line before delivery to final customer.
d. Neutral
By special command from tester this status can be set.
e. Locked by timer
After a certain number of incorrect inputs the EMS is locked for one hour and no inputs are accepted
during this time.
The following table describes the functions depending on EMS status.

Locking of ems
By engine shut off (ignition off by key) the EMS is locked after elapsing the timer (approximately 1.5
seconds). EMS accepts new start within this time without considering the result of new authentication.
In case of engine stalling the timing of EMS locking is as follows: without ignition off there is no time limit
for repeated engine start, after ignition off the time for repeated engine start is limited to the time
(approximately 1.5 seconds)
After elapsing this time new authentication is done or in case of limp home the input of user password is
requested again.
Key teaching procedure (refer to hi-scan pro manual)
The Key teaching is done at end of line of vehicle manufacturer, after replacing defective EMS at service
station or for providing or additional keys to the vehicle owner.
The procedure starts with EMS request of vehicle specific data from tester. The "virgin" EMS stores the
vehicle specificdata and the key teaching can be started. The "learnt" EMS compares the vehicle specific
data from tester with the stored data. If the data are correct, the key teaching can be started.
If wrong vehicle specific data have been sent to EMS three times, the EMS will reject the request of key
teaching for one hour. This time cannot be reduced by disconnecting the battery or other manipulation.
After connecting the battery thetimer starts again for one hour.
The key teaching is done by ignition on with key and additional tester command. The EMS stores the
relevant data in the EEPROM and in the transponder. Then the EMS runs the authentication for
confirmation of teaching process. The successfulprogramming is confirmed by message to tester.
If the key is already known to EMS from previous teaching the authentication will run and the EEPROM
data are updated. There is no change of transponder content (this is impossible for learnt transponder).
