Limp Home By Tester
If the PCM (ECM) detects the fault of the SMARTRA or transponder,
the PCM (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 PCM (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 PCM (ECM) via the special
tester menu.
Only if the PCM (ECM) is in status "learnt" and the user password
status is "learnt" and the user password is correct, the PCM (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 PCM (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 PCM (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 PCM (ECM) by a special sequence of ignition
on/off.
Only if the PCM (ECM) is in status "learnt" and the user password
status is "learnt" and the user password is correct, the PCM (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 PCM (ECM) is locked if the timer has elapsed
8 seconds. For the next start, the input of the user password is requested
again.
