guys this problem IMO needs immediate attention. my ABS...is GONE. i dunno when or how it happened, but it's gone. it doesn't engage anymore when i slam the brakes on hard, i tested it out on an open road while it was raining one night and i also noticed when i had to brake hard in traffic, my girl asked why the ABS didn't engage i was like uh oh. i read/heard somewhere that your ABS can be affected in some way by a speed sensor failure. is this true? because my speed sensor is in fact in need of a replacement. if htat's not the case, then what is wrong? does this problem need professional attention then? help me out guys cuz this is starting to worry me.
