Module diagnostics data

The module diagnostic data are attributed to the function numbers 2008 ... 2199. There are 4 diagnost­
ic information items in 4 consecutive bytes for each module. The function numbers of the diagnostic
data of the faulty module are therefore calculated as follows:
Function number = 2008 + (4 * module number) + information number
You can ascertain the module number of the first faulty module with the aid of the system
diagnostic data (function number 1937).
The following module diagnostic data is available:
1)
