My 2002 lexus ls430 has the check engine light on constantly but also when the brakes are held for more than a few seconds the abs light, the vsc off light, and the traction skid all come on. When coming to a stop the car does shake. But now the brake lights only flicker on then off. none of the fuses are bad also. All fluids are good. i really cannot find an exact explanation from what ive researched.

 

Wheel speed sensor??

RKW will chime in and he's usually spot on...

 

In the BMW world codes could be read to indicate the issue, and based on the symptoms, it's usually an ABS sensor, or the ABS pump itself. The sensor is the best case scenario, not really that big of a deal...

 

The shaking has something to do with the abs, so your abs wire('s) maybe pinched or cut and is throwing off a bunch of stuff in the car start by looking there.

 

I'm assuming you've read the codes from the CEL and get nothing? Or you've not read the codes yet?
Car shakes... from pressing the brakes or running rough?
Not sure we have enough details here.
Did this just start randomly, or you recently did something and then this started?
