[Dcm] Vehicle Diagnostic Communication Part 67 [Simulation 6]

Dsl (Diagnostic Session Layer) is Session related sub-module.It manages P2 time, P2* time, S3 time, etc.It also contains the PudId of CanTp that is actually used.

[Dcm] Vehicle Diagnostic Communication Part 66 [Simulation 5]

The content of AUTOSAR-Dcm structure consists of dsl, dsd, and dsp.Some are const defined and some are defined by variables for work.There are about 50 structures for configuration in total.
