DTC

FMB001 and FM3001 can read out DTC's (diagnostic trouble codes).

There is also an I/O element "Fault Codes" in newer firmware version. If

  • it is enabled and
  • Fault Codes are available on the vehicle,

they will be sent to to server under the AVL I/O ID - 281 encoded with Codec 8 Extended.

There is also an SMS command:

  • faultcodes: displays all visible fault codes.

There is no command that will list all supported DTC's supported by the current vehicle. Only current DTC's can be read out.

The DTC's that can be read by an FM OBD-II device depend on the vehicle make/model/year. Teltonika however does not have a Supported Vehicle List. Customers will have to

  • plug in the FM OBD-II device and
  • test the command to see
    • if and
    • possibly which
  • DTC's are returned and read.

Supported OBD-II protocols:

VIN

OBD-II VIN (vehicle identification number) has a length of 17 bytes and does not fit into Codec 8 protocol.

To get VIN:
