I have a 51 code flashing don't know the meaning. I think it is internal thermal fuse blown in srs module. I was a ford mech for 14 yrs and this thing has really got to me. I cant figure this thing out. No other codes are showing on obd2. I could really use your help. Was originally showin 43 and 49 flash codes and I fixed that now I only get 51. I got a used module and installed but I still get 51 flashing
