[DoCAN] Vehicle Diagnostic Communication Part 50 [UDS 11]

Review of P2 time.P2 time is 1 secondExplanation of P2* timeP2* time is 5 seconds.When the off-board tester receives NRC$78, it switches from P2 time to P2* time.When the off-board tester receives NRC$78 again, it extends P2* time from there.
