Calibration is a process that adapts a system (e.g. engine) to its environment by changing parameters in the ECU software. Employs CCP (CAN Calibration Protocol) or XCP (Extended CAN Calibration Protocol).
CANDI is an application software on the E-tester runtime system. It contains a configurable, graphical user interface to display diagnostic data received from ECU. CANDI supports, for example, the display of measurement data that is periodically requested by services such as readDataByIdentifier.
CCP is short for CAN Calibration Protocol. CCP describes a protocol for the data communication with ECUs and for the block transfer of memory areas.
Checker rules are defined in the ODX standard and provide (automatic) semantic and syntactic checks of ODX databases.
In the context of diagnostic communication, the client is the function of the tester that uses the diagnostic services. The diagnostic services are a subset of the functionalities of the tester, because the tester also has other functions such as database access or handling user interfaces.
In the context of diagnostic communication, the tester performs as a client that requests diagnostic services from the ECU that provides services as a server. See also master/slave.
A coded value is result of processing through support of base-data-types, encoding, byte order, masks, and computational methods. See also physical value and computational method.
The Comparam-Spec (communication parameter specification) is a category of ODX 2.0.1 and ODX 2.x.
The Comparam-Subset is a category that is newly defined in ODX 2.x.
A complex DOP is an ODX element for the description of complex data types for elements of the type parameter or for the use by other data object properties.
The computational method is the method that is used to convert physical values and coded values.
CSMA/CA is short for Carrier Sense Multiple Access/Collision Avoidance. CSMA/CA is an arbitration method that is used on CAN (see also arbitration).
