  • Is it solved? u still need help? According to Data Sheet No Data is obtained when -The IC waited for the period of time that was set by AT ST, and detected no response from the vehicle. It may be that the vehicle had no data to offer for that particular PID, that the mode requested was not supported. – Alejandro Vargas Oct 31 '14 at 13:25
  • Thanks,It is solved now.It occurs because the mode requested was not supported on the vehicle.You are right. – Devil Nov 03 '14 at 09:41
  • So, How to know the mode request is supported or not ? What kind of car is support that distance travelled mode? – Bulma Jun 17 '16 at 02:57

Unfortunately according to the SAE J1979 spec, vendor support for pretty much every single PID is optional. Commands, such as 0100\r\n give you an indication of which PIDs are theoretically supported by your vehicle, but whether an ECU will respond or not is completely vendor and vehicle dependent (and sometimes also depending on temporary/environmental conditions).
