Hi all!
All right ... so much said about it already but I`ve got few questions to SC`ers
About a week ago my breaks suddenly went out: usual symptoms - ABS+Brake lights on and hard pedal
I figured out that it was accumulator .. finallly went out after 11 years of service. I`ve ordered new one from Prior, but in a meantime decided to replace both relays.
When I did that and started the car - I heard buzzing sound. It was ABS pump motor. For some reason it was working non-stop. After about 10-15 mins of driving around it turned off and brakes were hard and lights went on too ... i guess thermal protection
worked and shut it off.
It acts really weird now, because sometimes it works but only with ABS light on a dash. And most of the time it doesn`t work at all.
I went through that little troubleshouting manual on Teves II ABS system. But ... no result.
Unplugged pressure switch connector from unit and grounded pin 4 like it was saying in that manual ... - same thing no result.
I`m pretty sure that it is some kind of electrical problem (or may be pressure switch?) because when it works sometimes everything seem to be fine (i mean hydraulics unit) beside of ABS light on a dash.
I was looking for some good reference on ABS electrical wiring but couldn't find anything but that book on amazon.com
it says it might take up to a month to get it ... may be someone has it already?
particulary i`m interested in Pressure sensor pinout and relay wirings
Thanks everybody.
