Number of control modules in the MOST network, value
The value indicates the number of control modules in the present MOST network. The number can be between 4-8.

Buttons in the keypad, status
The status displays if the selected button is activated or not

MOST-locked, status
The status indicates whether the MOST network is closed and communication possible.
- No
- Yes

Ring break diagnostic, status

Note! This parameter is only changed after a ring break diagnostic has been run.

After the ring break diagnosis has been carried out the status indicates if there is an open-circuit and if so the location of the open-circuit.
- OK
- Pos1 - Pos8

Hint: The number of possible positions varies depending on the number of control modules in the vehicle.

Network activity, status
Status indicates if there is communication in the MOST network.
- No
- Yes
