Resolution: 1/256 km/h per bit, 0 offset
Data Range: 0 to 250.996 km/h Operational Range: same as data range
Type: Measured
Supporting information:
PGN 65132
Note: Since FM FW sends this parameter as U16 (2 Bytes), value after floating point is discarded.
So data limit becomes [0-250]. This parameter could be send as 1Byte IO (as [0-250] fits into 1B,
but it is sent as 2B).
Firmware sends value which is already adjusted with bitgain.
Engine coolant temperature:
Temperature of liquid found in engine cooling system.
Data Length: 1 byte
Resolution: 1 deg C/bit, -40 deg C offset
Data Range: -40 to 210 deg C Operational Range: same as data range
Note: This parameter is to be interpreted as either a uint8_t or a int8_t, depending on the binary
value. Values from 0x00 up to and including 0xD2 are of the type uint8_t (unsigned integer).
Values from 0xD3 up to and including 0xFF are of the type int8_t (signed integer, two’s
complement). The value sent to the server has already been adjusted for the bitgain and offset.
Ambient air temperature:
Temperature of air surrounding vehicle.
Data Length: 2 bytes
Resolution: 0.03125 deg C/bit, -273 deg C offset
Data Range: -273 to 1735 deg C Operational Range: same as data range
Type: Measured
Supporting information:
PGN 65269
Note: Firmware sends value which is already adjusted with bitgain.
Driver 1/2 identification:
Used to obtain the driver identity.
Data Length: Variable (“*” delimited)
Resolution: ASCII, 0 offset
Data Range: 0 to 255 per byte Operational Range: same as data range
Type: Measured
Supporting information:
PGN 65131
Note: Firmware expects driver identification to fit into 24 bytes. According to captured driver ID
length either 1/2/3 IO ID’s will be sent to server (8 Bytes each). I.e. if driver ID length <= 8, only
one IO ID (129) will be sent to server, if VIN length >9 and <= 16, then two IO ID’s will be sent to
server (129,130), and if driver ID length > 16 and <= 24 then three IO ID’s will be sent to server
(129,130,131).
Engine fuel rate:
Amount of fuel consumed by engine per unit of time.
Data Length: 2 bytes
Resolution: 0.05 L/h per bit, 0 offset
