Limp Home By Tester
If the ECM detects the fault of the Immobilizer or transponder,
the ECM will allow limp home function of the immobilizer. Limp home
is only possible if the user password (4 digits) has been given to the
ECM before. This password can be selected by the vehicle owner and is
programmed at the service station.
The user password can be sent to the ECM via the special tester
menu.
Only if the ECM is in status "learnt" and the user password status
is "learnt" and the user password is correct, the ECM will be unlocked
for a period of time (30 sec.). The engine can only be started during
this time. After the time has elapsed, engine start is not possible.
If the wrong user password is sent, the ECM will reject the request
of limp home for one hour. Disconnecting the battery or any other action
cannot reduce this time. After connecting the battery to the ECM, the
timer starts again for one hour.

Limp Home By Ignition Key
The limp home can be activated also by the ignition key. The user
password can be input to the ECM by a special sequence of ignition on/off.
Only if the ECM is in status "learnt" and the user password status
is "learnt" and the user password is correct, the ECM will be unlocked
for a period of time (30 sec.).
The engine can be started during this time. After the time has
elapsed, engine start is not possible. After a new password has been
input, the timer (30 sec.) will start again.
After ignition off, the ECM is locked if the timer has elapsed
8 seconds. For the next start, the input of the user password is requested
again.
