Code 84 should reset itself upon switching off/on the ignition
Hmm, so there is no code 47 for the AYC, however the ABS & AYC are connected, so a fault with the ABS will bring up the AYC light too. I would first sort code 12 on the ABS (Front Left sensor) then see if the AYC light goes away with it.
