Vcs, Abs, Brake Light Is On

[ciba401k]

I have a 2005 RX 330 and while driving VCS, brake and ABS light comes on simultaneously after driving for an hour....... The lights disapear if I turn off the engine and restart the car..... then it takes another hour or so before they reappear........

I recently had the tires rotated and it may be that the technician accidently disconnected or loosened the sensor whilch I believe is near the tire/rotor........

Does this make sense?

Do you know where to locate these sensors or wiresfor these sensors near the Tire/rotor? A picture would be helpful

Thx a lot

the sensors are mounted on the hub of the wheel assembly. You will see a wire run going to it. The axle shaft has a toothed gear that the sensor reads for speed.. Could be one of them just has debris knocked loose after the tire rotation messing the sensor up...The sensors usually have a 10mm bolt holding them on. Be very careful to not damage the wiring going to the sensor...

here is how to do it....read post #9 for a picture I know it is a RX300 but probably is similiar....

This is my first post and it might be useful. I also had the same lights problem with my 2005 RX330 (although I did not get a tire rotation done). I brought my RX to the dealer and asked to run a diagnostic check. At first, they told me that they could not do anything since the light is no longer on. But as I was walking out the door without getting the diagnosis done, the service consultant flagged me down and told me that there were several other complaints about the lights coming on and asked me to leave my vehicle for a check up. Few hours later they called me and told me that they replaced the part that made the aforementioned sensors to come on. In short, the lights may be appearing due to your recent tire rotation job, or it may be something else.

PS the lights appeared 4-5 times in a span of a year.
