Hyundai Santa Fe (2006 year). Manual - part 195

IMMOBILIZER CONTROL SYSTEM

BE -241

When the key #1 is registered and key #2 is not
registered, put the unregistered master key #2 in
the IG/ON or the start position.
The engine cannot be started even with the reg-
istered key #1.

When you inspect the immobilizer system, refer
to the above paragraphs 1, 2 and 3.
Always remember the 10 seconds zone.

If the pin code ＆ password are entered incor-
rectly on three consecutive inputs, the system will
be locked for one hour.

Be cautious not to overlap the transponder areas.

Problems can occur at key registration or vehicle
starting if the transponders should overlap.

NEUTRALISING OF ECM

The PCM(ECM) can be set to the "neutral" status by a
tester.

A valid ignition key is inserted and after ignition on is
recorded, the PCM(ECM) requests the vehicle specific
data from the tester. The communication messages are
described at "Neutral Mode" After successfully receiving
the data, the PCM(ECM) is neutralized.

The ECM remains locked. Neither the limp home mode
nor the "twice ignition on" function, is accepted by the
PCM(ECM).

The teaching of keys follows the procedure described
for the virgin PCM(ECM). The vehicle specific data have
to be unchanged due to the unique programming of the
transponder. If data should be changed, new keys with a
virgin transponder are requested.

This function is for neutralizing the PCM(ECM) and Key.
Ex) when lost key, Neutralize the PCM(ECM) then teach
keys.
(Refer to the Things to do when Key ＆ PIN Code the
PCM(ECM) can be set to the "neutral" status by a scan-
ner. A valid ignition key is inserted and after ignition on
is recorded, the PCM(ECM) requests the vehicle specific
data from the scanner. The communication messages are
described at" Neutral Mode". After successfully receiving
the data, the PCM(ECM) is neutralized.
The PCM(ECM) remains locked. Neither the limp home
mode nor the "twice ignition on" function is accepted by
PCM(ECM).
The teaching of keys follows the procedure described for
virgin PCM(ECM). The vehicle specific data have to be un-
changed due to the unique programming of transponder.
If data should be changed, new keys with virgin transpon-
der are requested.

NOTE

• Neutralizing setting condition

In case of PCM(ECM) status "Learnt" re-
gardless of user password "Virgin or Learnt"

Input correct PIN code by scanner.

Neutralizing meaning .
: PIN code (6) ＆ user password (4) deletion.
: Locking of ECM (except key teaching per-
mission)

LIMP HOME FUNCTION

E6DD2F66

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 pos-
sible if the user password (4 digits) has been given
to the PCM(ECM) before. This password can be se-
lected 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. Dis-
connecting the battery or any other action cannot re-
duce 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 igni-
tion 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.
