 Replacement

Problems And Replacement Parts:

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)

NOTE

1. When there is only one key registered and yon wish to register another key, yon need to re-register the key which was already registered.

(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.

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.

NOTE

• 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 password (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.

NOTE

• Neutralizing Setting condition:
  • In case of "SMARTRA status", "Learnt"
  • Input correct Pin code by tester
• Neutralizing meaning:
  • Vehicle password (DPN Code) & SEK Code deletion.
  • Permission of New DPN Learning.

Teaching Procedures

1. Key Teaching Procedure

Key teaching must be done after replacing a defective PCM(ECM) or when providing additional keys to the vehicle owner.

NOTE

When teaching the 1st key, Smartra registers at the same time.

1. PCM (ECM) learnt status.

2. PCM (ECM) virgin status.

After replacing new "PCM(ECM)" scan tool displays that PCM (ECM) is virgin status in Key Teaching mode.

"VIRGIN" status means that PCM (ECM) has not matched any PIN code before.

Password Teaching/changing

1. User Password Teaching Procedure

The user password for limp home is taught at the service station. The owner of the vehicle can select a number with four digits.

The user password teaching is only accepted by a "learnt" PCM (ECM). Before first teaching of user password to an PCM (ECM), the status of the password is "virgin" No limp home function is possible.

The teaching is started by ignition on, with a valid key (learnt key) and sending the user password by tester. After successful teaching, the status of the user password changes from "virgin" to "learnt".

The learnt user password can also be changed. This can be done if the user password status is "learnt" and the tester sends authorization of access, either the old user password or the vehicle specific data. After correct authorization, the PCM (ECM) requests the new user password. The status remains "learnt" and the new user password will be valid for the next limp home mode.

If wrong user passwords or wrong vehicle specific data have been sent to the PCM (ECM) three times continuously or intermittently, the PCM (ECM) will reject the request to change the password for one hour. This time cannot be reduced by disconnecting the battery or any other actions. After reconnecting the battery, the timer starts again for one hour.

2. User password teaching

In case of putting wrong password, retry from first step after 10 seconds.

3. User password changing

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.

2. 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.
