Re: Is there a way to test an ABS pressure switch? Posted by SWEDECAR [Email] ![]() ![]() ![]() In Reply to: Is there a way to test an ABS pressure switch?, toplessBeachCar, Fri, 20 Apr 2007 08:51:34 Members do not see ads below this line. - Help Keep This Site Online - Signup |
If you mean the 5 pin multi pressure monitor switch on the side. It is quite a handful trying to figure out what pins should have continuity and not during different stages of the pump running.
I never remember from time to time but have to grab the Saab ABS manual with descriptions and my home made adapter to plug in and then measure my way.
For me, it is actually a lot easier to just unbolt and bolt another switch in to try with since I have one in stock if I suspect that one to be a problem.
I also have the Saab factory special scan tool to hook up if I want to run ABS testing while driving.
It is also possible that some corrosion have built up on that 5 pin connector so check that first of all.
Sometimes, a sloppy belt could have cut through some of the wires if the harness is not secured properly away from the belts.
Sometimes, someone could have swapped in the wrong relay for pump thinking it is just a regular 4 or 5 pin relay.
