It says the unit has already passed dcryptor.

 

Are you still experiencing an issue?

is the yellow led supposed to solid? it's not even blink. i didn't program the key bypass yet.

I would first master reset the unit: https://fortin.ca/en/download/61931/61931.pdf

 

Then re attempt programming.

 

If you still cannot get into mode selection, try doing it with only the pwoer connected to the unit.

i did. still solid yellow. and the fortin rf antenna not blinking either. the bypass firmware 70.39 it was 70.45 but they are same issue. remote start side firmware 1.25 hardware 7.0

Looking at the history of the unit, this module has been re used on multple vehicles.

 

I would suggest next trying a different module to see if its related to the used unit.
