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?

Mine was coming on occasionally, but just today started flashing intermittently. What is up??

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)
