Replacement Of ECM And Smartra
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 SMARTRA, it needs teaching the smartra. A new SMARTRA device replaces the old one and smartra need teaching.
1.
Things to remember before a replacement (PCM(ECM))
2.
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 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 scanner. If wrong vehicle specific data have been sent to SMATRA three times continuously or intermittently, the SMATRA 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.
  
•
Neutralizing setting condition
-
In case of PCM(ECM) status "Learnt" regardless 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 permission)
•
Neutralizing meaning:
-
PIN Code(6) & User P/Word(4) deletion
-
Locking of EMS(except Key Learning permission)

Neutralizing Of SMARTRA
The EMS can be set to the status "neutral" by tester
Ignition key (regardless of key status) is inserted and after IGN ON. If receiving the correct vehicle password from GST, SMARTRA can be neutralized. The neutralization of SMARTRA is possible if DPN is same as the value inputted by GST.
In case that the SMARTRA status is neutral, the EMS keeps the lock state. And the start is not possible by "twice ignition".
In case of changing the vehicle password, new virgin transponder must be only used. And in case of virgin key, after Learning the key of vehicle password, it can be used.
If wrong vehicle specific data have been sent to SMATRA three times continuously or intermittently, the SMATRA 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.
