### Fault codes / Event codes

The fault code is a hexadecimal number that contains encoded information on the fault location and fault type. This code informs the vehicle master computer, for example, whether and what type of event has occurred. At the same time, ALADIN uses this code, e.g. to display repair instructions.

Fault code: 0x00000000

Fault code: 000000h (alternative notation)

A complete fault code is comprised of the designation components: System, Fault Location, Fault Location Type and Fault Type.
The System, Fault Location and Fault Location Type together form the Fault Source. The fault code is normally shown as a hexadecimal number (long value).

System | 0 = Voith DIWA.5 automatic transmission 2 = VIAB 3 = DIWAHybrid |
Fault location | The fault location / event location that registers an event, e.g. transmission output speed sensor |
Fault location type | The fault location type indicating the probable cause of the event can be found here, e.g. transmission output speed sensor. |
Fault type | The fault type, e.g. short-circuit to ground at the connecting cable between the sensor and transmission controller |
