3.2.9.6Channel based diagnosis
The channel based diagnosis serves for detailing the identification based diagnosis. A structure is added to the device status for each faulty slot. This comprises of a header byte, a byte, the channel type and the channel number and a third which describes the fault type and the channel organisation.
