blue led doesn't stay lit while trying to program

Can't get past first step of programming. I release the button while the led is blue but it goes out.

I would check to see if there is power present on the yellow wire of the 20 pin connector. That wire should only have power when the key is on.

It doesn't have power until the key is on. I have tried a bunch of times to get this programed. I suspect it may be a faulty module.
If it is an evo-one you would also want to check the large pink wire on the 6 pin for the same criteria.

 

Also ensuring you have the correct firmware flashed into the unit for the installation type and vehicle being worked on is a good thing to double check.
