Hey guys,

at times while driving my ABS light comes on and stays ON while the "trac off" light flashes..this only happens once in a while. Maybe like 1-2 times a month. Very weird behavior i must say. Anybody seen this before?

I have a 2000 ES300 with 63k

oops, didn't even realize I posted this in CL of SoCal. My mistake, can it be moved to ES300 330. Thanks

Are you able to get a scanner on it to check the sensors?

Rollin'ES3

well since it only goes off once in a while i havnt had any luck getting it scanned, but next time I'm gonna be prepared..lol

I heard from sombody that when the trac off light flashes that is LIMP mode....

what does that mean?

^Limp mode is when the pcm uses pre-programmed information instead of what would normally be input by the sensor or what have you.... so you can still drive the car, ya mean?

In your case the trac control and ABS is shut off whenever the false or no input is sent to the pcm and/or ABS control unit, which sounds intermittent. Probably a wheel speed sensor

The wheel speeed sensors are used for the ABS and trac control

I figured the wheel speed sensors a while back ago, So i inspected them all and cleaned them up. But maybe it got dirty or some shavings on them as it attracts metal. I dnno I may give up on this.
