ABS/Brake Dash Light 1999 LC

[BritLC100]

I own a 1999 Land Cruiser with 261k miles on it. Recently the ABS and brake light have been coming up on the dash randomly with the annoying high pitched alarm. The brakes feel completely normal and the ABS light does not through a code for a OBD Scanner or even store a code. I have scanned it multiple times and have not had anything show. The ABS/Brake light come on most commonly when starting the vehicle and most of the time will go a way a minute or two after the vehicle has been started. Occasionally it will come on while driving and refuse to go away. The only solution I found that works 50% of the time if the ABS Light will not go away is turning the vehicle off and restarting it.

Does anyone have any recommendations to start trying to properly diagnose this ABS/Brake dash light? Wheel speed sensors seem to be what I hear most commonly should be the first fix. I am not sure if it not throwing any codes or storing any could be a hint to anything. Also, let me know if there is any way you can disable the audible alarm for the ABS (fuse to pull?).

I just purchased the truck in June so I am still learning a lot about them. Any help is appreciated, thanks!

Basic/cheap Scanners will not show ABS data, take it to a shop if possible and scan again.

My mechanic said his did not show any codes. Could be a possibility that he was using a cheap one…? Have a friend who also used his which was a nicer one, still nothing. My last resort will be taking it to a local Toyota guy. Thanks for the reply.

Just a reference point, if it helps - when my right rear wheel speed sensor was damaged and working only intermittently, I got the dash lights but no beeping. My dash showed ABS / VSC OFF / BRAKE. I never checked for codes because I knew at the time what the damage was. And my brakes were noticeably different.

Gotcha, good to know that the ABS alarm may not go off in the case of it being related to a speed sensor. Thinking it could be related to ABS Pump or losing pressure in accumulator or brake booster from what I am hearing from a Facebook LC page.

Get a copt of TechStream up and running:

How-To: TechStream In 5 Minutes

Getting Techstream up and running can be a bit of a pain. Hopefully this helps someone get started quickly. Step 1: Purchase an OBD-II / Mini-VCI interface. - I have sold out of my cables and supply chains are back in order, so no reason to purchase more. Anything like this will work: Mini-VCI...

Then once the ABS light comes on, plug in and read the code WITHOUT turningoff the truck. ABS codes are generally not stored. I needed to do this to diagnose a wheel sensor.
