This is the procedure for resetting a TMCC locomotive.
1. Ensure the TMCC base is connected to the track and all power is off.
2. Slide the "Run/Program" switch on the engine to "Program". You may have to turn the engine upside down and push the front truck to one side to see the switch.
3. Place the engine on the track and turn on track power
4. Using the remote, press "ENG", and then a number (0-99)
5. Press "set". If successful, you will hear the horn sound and/or see the headlight flash.
6. To set the engine sounds and feature type, press Aux1 and then 8. Once set, you should hear one or two horn blasts and/or see the lights flash.
7. Turn power off, slide the "Run/Program" switch back to "Run", then turn the power back on.
It is a long shot, but maybe the run/program switch was installed backwards or is broken.
