1997 Civic abs light issue
 

Hello all maybe some one out there can help me on this one. I did all this on a 1997 civic ex I just changed the left and right forward cv shafts(half shafts). Also changed out the right rear and left rear trailing arm bushing. When I did the trailing arm busing I disconnected them but did not remove them from the car. During this I did the rear shoes and while bleeding the brakes I broke bleeder screw off and I changed out the left brake cylinder and bleed the rear brakes. Now I have a ABS light on and the codes as 12,16,18. Before I did this no light any ideas on this sorry for being so long .

Thanks
