Neutralizing of ECM/ICM
Neutralising Of ECM/ICM
The ECM/ICM can be set to the "neutral" status by a tester.
A valid ignition key is inserted and after ignition on is recorded, the ECM/ICM requests the vehicle specific data from the tester. The communication messages are described at "Neutral Mode". After successfully receiving the data, the ECM/ICM is neutralized.
The ECM/ICM remains locked. Neither the limp home mode nor the "twice ignition on" function, is accepted by the ECM/ICM.
The teaching of keys follows the procedure described for the virgin ECM/ICM. 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.
