To reset the PCM (Powertrain Control Module) code on a Lexus IS300, you can disconnect the car's battery by removing the negative terminal for about 15-30 minutes. This will clear any stored trouble codes. After reconnecting the battery, drive the vehicle for a short distance to allow the PCM to recalibrate. Alternatively, you can use an OBD-II scanner to clear the codes directly from the vehicle's diagnostic system.

When you say "reset" button, I assume you have a check engine light on. There is no reset button. You either need to have the PCM scanned with a scan tool to see what fault code is indicated or you can try to clear the code(shuts light off) by disconnecting the battery for 30 minutes.May come back on if failure sets whats called a "hard code".Need to address if hard code.
