Get your ABS checked by a ford technician ASAP, ABS problems are a safety issue..
The ABS light indicates that the computer has detected a malfunction in the ABS system and has diagnostic codes and data stored which would be essential in diagnosing the problem.
A technician with a scanner could access the diagnostic codes and data and then be able to give you a diagnosis.
I don't have P1155 listed but P1158 is an oxygen sensor code indicating that cylinder bank 2 is running rich, or so the oxygen sensor thinks. Get this checked too.
