LIMP HOME FUNCTION
1. 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.
