Hi group, I have a real problem . My 2000 rx300 has the abs pulsing when coming up to a normal stop..I took it to the dealer who said both rear abs speed sensors were bad. I am disabled now and cant work on it anymore so I had them replace them at a cost of $500 plus labor. Then I get a call saying that it didnt fix the problem,that both rear axle tone rings are bad and the cost is $2000 plus labor. I read in a post by Lexmex where he disconnected the abs. I know the abs is a safety feature, but I cant afford to sink this much money in an abs system. My question is how would I disconnect my abs, is it as simple as pulling a fuse (I heard this ) an if so which fuse? I assure you there is no liability in letting me know.. Larry It will be greatly appreciated as the pulsing is getting really bad.
Same problem with my 98 GS300. ABS started pulsing intermittently , especially when the wheels were turned to the right. Then on occasional stops - then every stop.
Code said passenger front abs sensor - replaced.
Code said passenger rear abs sensor - replaced.
Took it to a different mechanic who had seen it many times. Replaced the rear passenger axle with a used one for $250. There was a protective cone/ring about 5 inches in diameter that had rusted and stopped protecting the sensor. Said it allowed particles and dirt to corrupt the system. Also said the rear sensor was probably not the problem in the first place. Did not replace the cone/ring so i have to be careful to keep it clean. Otherwise, problem solved.
If the pulsing annoys you, unplug a sensor and the abs system shuts down. You then have regular braking, just without the safety, until you have it repaired.
You could try the fuse - I didn't but I suspect it will stop the pulsing when not warranted.
Each wheel has its own sensor - it's a cable about 2 feet long that plugs into the inside of each wheel and senses when speeds don't match. Then the CPU pulses brake pressure like pumping the brakes to avoid skidding.
I'm no DIY'er but a mechanic can do it pretty easily - takes minutes to remove and replace. But removing the fuse might stop the pulsing. Try it and let us know.
