I have just has a replacement high pressure pump fitted to the braking system on my 1991 9000 2.3 Turbo. Following this, the garage could not get power assist on the brakes to work. They traced this to the wiring on the pressure relief valve, and have replaced some of the wiring. The car now has power brakes, but the ABS light will not go out. There were no faults with the ABS before the pump was replaced. The car's manual says that the ABS light will only go out once brake pressure has built up in the accumulator. Could it be that the sensor which tells the ECU if that pressure is present is part of the relief valve wiring ? If so, does anyone have a wiring diagram for this or can anyone tell me what pin on the ECU senses the pressure (and is good pressure 0V or 12V at that pin) ? I know that I could have the car taken to a garage with the Saab ABS test equipment, but the nearest one is 175 miles away. Does anyone know how to retrieve the ABS fault codes without specialised test equipment ? (I know that on some cars you can do this with a length of wire and a light bulb).
