Field Description:
IGNITION
This is a 1 byte field that indicates the status of the vehicle
ignition.
0x00 = Ignition OFF
0x01 = Ignition ON
Note: The methods used to determine the ignition status actually
detect when the OBDII bus is responding to requests, and not the
ignition status. It is possible that some vehicles will continue to
respond while the ignition is off. All vehicles are required to
communicate when the key is in the on position and the engine is
not running.
OBDII_STAT
This is a 1 byte field that indicates if a second scan tool is
connected to the OBDII port.
0x00 = No Tool
0x01 = Tool Connected
0xFF = Scan tool status unknown (device in standby mode)
