Hi! I have a problem with my is250 for 5 month.
In february I replace my bc-racing (was need to rebuild) with stock suspention. From this time I have error time to time. The error is: Right Front Wheel Speed Sensor Signal Malfunction. The Lights is: ABS, check VSC, AFS, EPS.
First, I cleaned the connector of right front abs sensor.
Then I have checke the wire - good.
The guys from Lexus Service told me, if ABS sensor is broken - the error will be light all the time. When it comes from time to time - it's wire problem.
So, I replaced the wire. But the error cames again on the second day.
I think, how I can remember, error comes only when i drive with speed <20 mph, and it often turn off when speed more then 20 mph.
What can it be? Help, who knows...

p.s. sorry for my English

 

If you've replaced the wire to the ABS sensor already, the next step is to replace the actually ABS sensor...which is the entire hub assembly.
