Neutralizing of ECM

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. can be set to the "neutral" status by a scanner.If wrong vehicle specific data have been sent to SMARTRA three times continuously or intermittently, the SMARTRA 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 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 SMARTRA three times continuously or intermittently, the SMARTRA 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.
