When Error 02 occurs while programming it indicates that the command station did not receive a response from the decoder. Most decoders will briefly energize the motor to indicate the command has been received. The command station can detect that.


If an Error 02 is occurring, check the following items:

  1. Connection from the command station to the programming track.
  2. If a newly wired programming track, verify the connections to the programming track.
  3. Verify the decoder is wired correctly (if recently installed).
  4. Check the electrical connections between the wheels and the decoder.
  5. Is the locomotive close to the programming track's feeders?
  6. Are the track and wheels clean?
