diagnosticLevel sets a diagnostic session code for a signalset. Some commands require a diagnostic level to be activated in order to respond.
Pelican marks this field as deprecated. For new definitions, use the din and dout properties on each Command.
Format
The field is optional. The OBDb signals schema requires a string with two characters. Pelican reads these characters as a hexadecimal byte.
The correct session code depends on the car and its module.
Command session codes
The command’s din sets the session code before that command runs. Its dout sets the session code after the command finishes.
