A quick, firm, jab & release of the brake pedal should center rhe valve and turn the light off. If the pedal is still mushy after the gravity bleed, you will need to perform the automated bleed with a capable scan tool, then bleed each caliper again. You may need to repair the ABS before the automated bleed will work. The automated bleed operates all of the solenoids in the EBCM and moves any trapped air into the steel lines just outside the EBCM, that's why the calipers need to be bled again, (to get the air out of the system).
