Byte Z is the start address of the diagnosis area for this DDL
participant in the controller.
The bus coupler can recognize if there is a short circuit or open
load in a valve solenoid. The diagnostic data is not different. A
short circuit may occur if e.g. the isolation of the valve solenoid
has been damaged. An open load may occur if e.g. the valve
solenoid in a valve has blown or if a contact has been
interrupted.
