(2) PCM(ECM) virgin status.

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

2. 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.
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 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 incorrect user passwords or wrong vehicle specific data have been sent to the PCM(ECM) three times, 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.
