* OBD2 Live Sensor Data

* values of the OBD2 sensors provided by the vehicle.

* Its contents are to be interpreted as follows:
* the indices defined in Obd2IntegerSensorIndex are to be used to
* read from int32Values;
* the indices defined in Obd2FloatSensorIndex are to be used to
* read from floatValues.
*
* For example, int32Values[0] corresponds to FUEL_SYSTEM_STATUS, and
* floatValues[0] corresponds to CALCULATED_ENGINE_LOAD.

* OBD2 Freeze Frame Sensor Data
*
* This property uses COMPLEX data to send a snapshot of the values of the
* OBD2 sensors provided by the vehicle at the time that a diagnostic
* troubleshooting code (DTC) was recorded by the vehicle.
*
* Its contents are to be interpreted as follows:
* the indices defined in Obd2IntegerSensorIndex are to be used to
* read from int32Values;
* the indices defined in Obd2FloatSensorIndex are to be used to
* read from floatValues;
* stringValue is the DTC that caused this freeze frame to be recorded.
*
* For example, int32Values[0] corresponds to FUEL_SYSTEM_STATUS, and
* floatValues[0] corresponds to CALCULATED_ENGINE_LOAD, and a possible
* valid stringValue is "P0176" to indicate a malfunction of the fuel
* composition sensor circuit.
