Control Module: Testing and Inspection
Data Exchange between Transmission Control Module (TCM) and CAN-Capable Control Modules, checking
Note:
^
The exchange of data between the individual control modules is carried out by means of a bus system.
^
"CAN Bus" describes a system to carry and distribute data.
^
The wiring connections between the control modules, over which the data are transmitted, are described as data lines.
^
Data are transmitted serially, that means in sequence, over these data lines to the attached control modules (e.g. engine RPM, accelerator pedal
position).
