There is no procedure to reset the pcs warning light on a Lexus vehicle. This is a safety feature so that You don't drive the vehicle when it is damaged. If Your light when it shouldn't be the first thing You should try to do is disconnect the battery for 10 minutes so that it can reset itself. This will restore the vehicle to it's factory settings and should get rid of the light. If disconnecting the battery didn't fix it You're going to need to take it in to a shop or use a scanner tool to get rid of this light.

To reset the Lexus PCS warning light you will need to use an OBD II scan tool to clear the fault.
I have 2010 Toyota Lexus Lx570. The PCS light is coming on in the meter of the car. I have diagnosed the car but no code is coming in the car. So please guide me what could be the problem?

I have a 2015 IS350. There is a button under the steering wheel that toggles the PCS on/off. I accidentally pressed it and PCS light came on my dash display (disabling PCS). Press again and it reactivated and PCS light turned off
