A function is limited so that the system still functions, to protect components or for safety reasons (for example the throttle angle).

Any diagnostic trouble codes (DTCs) are stored in the control module memory. The data can be read off using VADIS/VIDA.

Signals 
The table below summarizes the input signals to and output signals from the Engine Control Module (ECM). The signal types are divided into directly
connected signals, serial communication and controller area network (CAN) communication. The illustration below displays the same information with
the Volvo component designations.
