the granada won't have any fault codes readable by the vast majority of fault code readers

you plug a light into the 3 pin diagnostic plug by the battery and it'll flash some sequence of lights to give you very basic info

and it won't be on the afm's as they won't read as a fault

remove the afm's and do the poke test i told you about earlier in the thread and change the one that sticks

there's a guy on facebook who's selling some afm's now that i can post up for you, but i'm not sure if i can post up stuff for sale from other folks so you'd have to get a mod to see if that was possible without me getting into trouble
