A few years ago I reported an error in the light function settings in the TCS function decoders, today I found the same error is still in place so am reporting it once again. I don't remember if at the time I checked the other settings, but the ones I needed at the time and are still incorrect are for ditch lights. The result is one ditch light is the ditch light of the opposite phase, the other result is a constant dim light instead of the 2nd ditch light. I haven't evaluated what other function settings might be incorrect

copied from the original post:
In the TCS FL4and FL2 function decoders, one of the values to make a function perform as a ditch light is incorrect. The CV value choices should be 10 or 11 for forward operation, 25 and 26 for reverse, and 41 and 42 for non-directional operation. The present values are a value of one too low, making one output non-operational when one uses a value of 9, 24, or 40 that are stored in the DecoderPro files.
