I've been working on my ABS problem for awhile now--here's whats happened so far--
First off, i got both lights on and hard pedal symptoms. i originally took it to a place and they pulled a code 12 which was to replace the module. I bought a used one from a fellow member. i installed it and cleared the codes and everything was fine. The next day i was at th AF muesem and when I came out my battery was weak. I heard the hyd pump motor running--popped the hood and the relay was shorting out due to some stripped wires. Well, i fixed the wires and bought a new relay and that didn't work. i pulled the codes and got a 35 or 36. So i cleaned and did all the checks on them that the Chilton's manual stated and they both passed. Went back to the relay and jumped the pins to do the test and the hyd motor came on before I put the Ignition switch to run. however, i started the car and the the lights went out and everything was working fine. Put the relay back in and after a couple miles the problems back. My best guess now is that the pressure switch may be faulty. Since all the system was fine with the jumper wire, i figure the switch isn't telling the pump to come on. is there a simple test for the pressure switch before i buy a new one? Sorry so long!
