Kia Soul 2014-2019 PS Service Manual / Body Electrical System / Immobilizer System / 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.

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.
