Fast XFI no check engine light

[CS99]

Just want to check and see if XFI 2.0 is supposed to turn on the check engine light when I go to start my GN. Noticed that it is not coming on.

Only on if a fault detected.

Mine does the same thing randomly..... It is supposed to flash the CEL if a fault is detected at start up from my understanding

Thank you!
