1994 850 air in abs system

Post by snugani »

The other week I had a brake line go out and empty the reservoir. The abs light came on shortly after this. After replacing all the lines and bleeding the brakes the light is still on.

I have the system without tracs, and the abs always worked until this happened. This leads me to believe there is air in the system. I got code 442 from the obd 1 system which I believe means low pump pressure.

Does anyone know how to get the air out? Aside from the light being on the car stops great and the pedal is firm

The only way is to use a pressure bleeder and try to push the air out.
