Default LS400 Brake conversion done BUT

These lights are now on and wont go away. I even unplugged the battery for an hr or so and they still came back on...any ideas?

also my brake pedal feels kinda soft (bleed all the air out) its now as stiff as it should be, cars stops on a dime though. Lasty...and this could be from just testing the brakes hard, as i drove to make sure everything was good, the pads/rotors were smoking

any help would be great. Thanks fam!!

Did you take out the abs sensors? They can be either not put back in flush or they could have been damaged.

I'm being totally serious and not trying to sound like a douche cuz maybe the same thing happend to someone else but is your gas tank really on empty? Only asking because that light is on too. Not sure if your gauges are flipping out too.

I am having the same issue and you need to do a zero point calibration to turn those lights off as anytime you mess with suspension geometry the vsc needs re calibrated, The rca's you put in did it.

That will not work he needs to have the vsc re calibrated that is exactly why it is on. No point in trying to clear it as it will not go off until the zpc is done, This is a common issue .

I am still looking for the diy way to do this yet otherwise you could pay a shop to do it which does not have to be a Lexus shop just one with a good quality scan tool.

That is because your car is a 98 later models need to do this however I can't remember the cut off year maybe 01+

Well I have a 99 and I swapped the rcas twice. First time was last year and I had no problems. I then took them out and reinstalled after winter. This time I accidentally pulled the driver side ABS sensor slightly. Now my lights are on too. So I'm sure you damaged the sensor without knowing. Those sensors are super sensitive.

My car is an 01 and I didn't need to do this with either the RCAs or calipers.

If your car has stability control then you need the re calibrate the vsc but if not then you are in the clear.
