Hi, Just wanted to share some of the experiences that I went through. I too replace sensors and such. To my surprise nothing was working. I came upon a post from a Lexus Tech and he gave me the following info. Disconnecting the battery will not clear the ecu memory. It must be done from the computer port under the dash right under the steering wheel. I used a paper clip to jump top row from left number 3 pin to bottom row from left number 5. With the key off. Make the paper clip so that you can hold it connecting both pins. (unless you have some help) After making the connection, turn the key to the on position. You will see the VSC, Engine, and perhaps Abs lights start flashing. Turn the ignition off. remove the clip. Your computer memory is now cleared. Start your car and the lights should not come on. I went through dealers and mechanics before finding this information. Don't be scared to do it. I have saved thousands by working on my own RX300. Let me know how it goes and if you have any questions. Good luck. Robert :D
