Returns OBD info. Protocol, VIN, AdaptiveTiming value, requested PID counter, OBD application state, available vehicle PIDs, mil status, number of DTCs<br/><br/>
For example: Protocol:6,VIN:WVWZZZAUZFW125650,TM:0,CNT:11,ST:PROTOCOL DETECTION,P1:0x98180001,P2:0x1,P3:0xE0800020,P4:0x0,Fuel:OFF,MIL:0,DTC:0,ID0
For example: Protocol:6,VIN:WVWZZZAUZFW125650,TM:0,CNT:11,ST:PROTOCOL DETECTION,P1:0x98180001,P2:0x1,P3:0xE0800020,P4:0x0,Fuel:OFF,MIL:0,DTC:0,ID0

Protocol:6 – specifies car supported protocol
Protocol:6 – specifies car supported protocol<br/>
VIN:WVWZZZAUZFW125650 -specifies car vin number
VIN:WVWZZZAUZFW125650 -specifies car vin number<br/>
ST:PROTOCOLDETECTION- specifies OBD application state
ST:PROTOCOLDETECTION- specifies OBD application state<br/>
P1:0x98180001,P2:0x1,P3:0xE0800020,P4:0x0 - specifies available vehicle PIDs. These values specifies available parameters in car. If all pids values 0 (P1:0x0,P2:0x0,P3:0x0,P4:0x0), it means that OBD parameters is not readable.
