Hi,
My newly aquired 92 CS carlsson has ABS and TCS lights lit. I am not too bothered about the TCS just yet but would like to sort the ABS very soon.
Symptoms/status is:
-Anti-lock light on Most of the time, but occasionally not
-Brake pressure light on for 45 seconds at start-up after overnight stand
-Brake Pressure light on for 10 seconds after 30 minute stand
-ABS Pump runs ok and shuts off shortly after pressure light extinguished
-Fluid level rises and above max mark as expected when off and drops to just below max when system pressurised and pump is off
Also
-TCS Cntrl light always on.
-TCS in speedo light sometimes on (intermittent)
-Can sometimes pursuade Anti-lock light to extinguish by driving about 5 miles... stopping for about 15 minutes, driving another 5 miles and stopping for 5 minutes then starting up. After this driving sequence (or something similar) Anti-lock light sometinmes goes out and stays out for a variable amount of time (5-15 minutes)
-Pressure light does not come on when driving even after a few consecutive brake applications
So far I have...
-Cleaned wheel sensors
-Taken car to authorised SAAB dealer who kept car a week, but couldnt read codes with Tech-2 and had no I-sat
-Performed resistance checks from ABS connector (All check out ok apart from one ... diode check between pins 14 and 1 which indicates a shorted diode ie continuity in both polarities) diode works fine out of circuit ! and continuity between pins remains when diode removed.... not resolved
-Replaced diodes 385, 303A and 303B (no change)
Any advice would be welcome...
