DTC

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

There is also a "Fault Codes" AVL ID in newer firmware versions. If

  • the elment is enabled and
  • DTC's are available on the vehicle,

then DTC's  will be sent to the 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 DTC's supported by a vehicle. Only current (occurring at reading time) 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:



  • No labels
