No blue light and no red light

Just yellow light if i start the truck manually.

If not already done from when we spoke earlier
 

  1. reset the unit: https://cdn02.fortin.ca/en/download/61931/61931.pdf
  2. go back to the flash link and enable options c1 + d1 + d2, (leaving A1 to A11 On)
  3. go back to car and reprogram
  4. go back to flash link and run dcryptor


Before doing all that though, check if your Flash Link has the latest update 4.05. Go into Help (way up top left corner) then Flash Link Firmware Update. This sounds like it may your issue since without this update, your dcryptor may never update correctly back into the evo.
