The diagnostic data bus (SCP) consists of two lines, the 4-PB9 (GY/VT) and the 5-PB9 (BU/WH), along which communication with the diagnostic
tester still takes place, even if one of the two lines is broken, has ground contact or a short-circuit to a battery voltage. Should one of these faults occur,
this is stored and can be read out. If both lines are damaged, communication with the modules is no longer possible.
The diagnostic data bus is a one-strand line 8-CF29 (WH/VT), along which communication is no longer possible if the line is broken, has ground contact
or a short-circuit to a battery voltage.
