Notes
This PGN is transmitted in response to a PGN 126208 Request Group Function message. Fields 1, 3, and 4 must each be fully specified in the request in order for this PGN to be
transmitted.
This PGN does not respond to ISO Requests (PGN 59904).
Although this is a fast-packet message, the version with this PID fits into a single CAN frame.
To change the state of the Simulate Mode option (field 5), use the Command Group Function PGN 126208, specifying the individual fields in PGN 126720-35 as follows.
