Current MMI3G software update Back-up documentation following software update unsuccessful

Technical background: ¾

¾ ¾

Control unit 1 for information electronics cannot restart automatically following update and parameterisation.  The control unit no longer responds to requests from SVM. SVM generates the response "Hardware prüfen" (Test hardware) for all other MMI components.

Procedure: 1.

The following appears in the MMI display after update:

2.

Select "Dokumentation abbrechen" (Abort documentation).

3.

The MMI automatically initiates a restart.

4.

Wait until the MMI display is populated again.
