Anybody have any idea why an abs light would flash intermittently on an 02 Tundra?

This has been going on for at least a month or so. Sometimes when I start it the light will flash, but if I turn the ignition off and turn it back to the ON position, the light will go out. Sometimes it takes a couple cycles. I've also noticed that if I drive, it tends to go off after a few stops when I get up around 30 mph, but not always (sometimes I get to my destination without it coming on). Other times, it'll be off, then come on after a stop (light a stop sign or a stop light). Sometimes it'll come on several times in the same drive, sometimes it won't come on for over a week, but it always seems to come back.

I finally decided to do a little research, but I couldn't find much information. I did the pin 4-13 short to try to read a code. As far as i could tell, there was no code. It just made the airbag, cruise & abs lights flash at regular intervals (no pausing or anything like you'd see if it was flashing a code).

Anybody have any ideas? I'd hate to take it to the dealer and have to pay $80 for them to find nothing, since it's intermittent and probably won't happen when they check it, and no codes seem to be stored. Also... just a side note, I have a scangauge and it's not pulling any codes either (wouldn't really expect it to though, since it's an abs, not a check engine code).

If anybody can offer any help, I'd appreciate it. Thanks in advance.

Check your brake fluid level. Low brake fluid will make my E Brake light flash on and off, maybe it does the same for the ABS light?

Have you checked the condition of your brakes? I did not see that mentioned. If you don't want to do it take it to a brake shop and let them inspect the brakes... maybe it is time? They should inspect for free.

The sensor(s) are not working correctly????????
Did you had the truck on a lift recently and turned the wheels???
I had warp rotors and my ABS light came on in the winter in the snow when using 4wd.
Now no snow, replaced the rotors, no more light.

The brake fluid isn't topped up, but it's about halfway between the min & max lines.

It may be due for a brake job. I planned on replacing the brakes & rotors this summer, but I haven't looked at 'em in awhile. I'll take a look at them when I get a chance.

Thanks!

Edit: nevermind... tried moving the discussion to the brakes section, mods didn't like it.
