trying to turn off my check light (or at least find out what's wrong with it) and i get no blinks/flashes when the service port is connected

i know i have bridged it successfully as i can turn it on and off and i get a change in engine tone (due to the ignition timing going from static/mapped) just no flashes

i've removed the 7.5A fuse as per the reset procedure, still nothing!

any ideas? i searched on here and a few threads popped up but none of them had resolutions
