Check Data List Parameters

·   Using TECH 1, it is possible to display the various input and output parameters (actual values) of an electronic vehicle system.

·   The "Quick Check F0:DATA LIST" table shows the nominal values for each system parameter.

·   These nominal values ("Quick Check F0:DATA LIST" table) can be compared with the actual values (TECH 1 Display) for evaluation of the system status.

     Procedure:

-   Observe the actual values displayed by TECH 1 over a period of time (depending on the relevant parameter);

-   During observation, determine an average value;

-   Compare this average value with the prescribed nominal value.

·   The column "Terminals" indicates the affected terminal for each control unit and, when used together with the system's circuit diagram, enables more thorough diagnosis.

·   If the TECH 1 displays "NOT USED", this indicates that this parameter is not evaluated by the system.
