Replacement Of Ecm And Immobilizer
In case of a defective ECM, the unit has to be replaced with a "virgin"
or "neutral" ECM. All keys have to be taught to the new ECM. Keys, which are
not taught to the ECM, are invalid for the new ECM (Refer to key teaching procedure).
The vehicle specific data have to be left unchanged due to the unique programming
of transponder.
In case of a defective Immobilizer, it needs teaching the Immobilizer.
A new Immobilizer device replaces the old one and Immobilizer need teaching.

Things to remember before a replacement (Keys & Additional registration)
|
| 1.
When there is only one key registered and you
wish to register another key, you need to re-register
the key which was already registered.
|
| 2.
When the key #1 is registered and master key #2
is not registered, Put the key #1 in the IG/ON or the
start position and remove it. The engine can be started
with the unregistered key #2.
(Note that key #2 must be used within 10 seconds
of removing key #1)
|
| 3.
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 registered
key #1.
|
| 4.
When you inspect the immobilizer system, refer
to the above paragraphs 1, 2 and 3.
Always remember the 10 seconds zone.
|
| 5.
If the pin code & password are entered incorrectly
on three consecutive inputs, the system will be locked
for one hour.
|
| 6.
Be cautious not to overlap the transponder areas.
|
| 7.
Problems can occur at key registration or vehicle
starting if the transponders should overlap.

Neutralizing Of ECM
The ECM can be set to the "neutral" status by a tester.
A valid ignition key is inserted and after ignition on is recorded, the
ECM requests the vehicle specific data from the tester. The communication messages
are described at "Neutral Mode" After successfully receiving the data, the ECM
is neutralized.
The ECM remains locked. Neither the limp home mode nor the "twice ignition
on" function, is accepted by the ECM.
The teaching of keys follows the procedure described for the virgin 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 ECM and Key. Ex) when lost key,
Neutralize the ECM then teach keys.
(Refer to the Things to do when Key & PIN Code the ECM can be set to the
"neutral" status by a scanner. If wrong vehicle specific data have been sent
to immobilizer three times continuously or intermittently, the immobilizer will
reject the request to enter neutral mode for one hour. Disconnecting the battery
or other manipulation cannot reduce this time. After connecting the battery
the timer starts again for one hour.
