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).
