In Reply to: Anti-Lock Light on, symptoms.... posted by Beej 86 325es on May 06, 2001 at 23:22:56:


Just today, my ABS started kicking in at about 7 mph until I stop. It did it all day tonight when my light turned on and it doesn't kick in anymore.
The Bentley is very vague on this. It suggests inspecting the pulse wheels on the hubs, but those were replaced about 5,000 miles ago. Is my ABS unit bad?
Thanks.

Check the pulse rings to be sure they are clean, then check the resistance at all four wheel sensors. One will likely be different (substantially) from the other three. Resistance should be around 1.1-1.2K Ohms or something like that. Find the outlier and replace it. That should fix the problem.
