Antilock Brake Warning Light
Hey y'all, I'm new to the LS400, but I am very excited as I read all about its awesome potential. I've been reading about the LS400 and learning all I possibly can about how to repair common problems with it, but a new one came up today that I'm a little foggy on. My antilock brake light comes on every once in a while (like every couple times I drive the car, the light comes on right as I start the engine). Now it seems to stay on all the time. Any ideas at what it might be?

The other day I went from wheel to wheel, taking the tire off and inspecting the speed sensor (its a little cylinder with a 10mm bolt holding it to the wheel hub) and the front two looked really good, covered in white grease, but when I got to the back two, one was really gunked up. I cleaned the speed sensor off with some white lithium grease in a can (i was a little apprehensive about using brake cleaner on a $140 part), and then sprayed some white lithium grease into the port the speed sensor came out of. I bolted the speed sensor back into place and haven't had a problem with the antilock light coming on again since. Hope that helps! (By the way, I have a 1990 LS 400)
