Neutralizing Of ECM

The PCM (ECM) can be set to the "neutral" status by a scantool.

A valid ignition key is inserted and after ignition on is recorded, the PCM (ECM) requests the vehicle specific data from the scantool. 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. (Example: when a key is lost, neutralize the PCM (ECM) and then teach keys. (Refer to TEACHING PROCEDURES . 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.
