In this guide, you will find step-by-step instructions on how to reset the Lexus check engine light.
What you need
Follow these steps to reset the Lexus check engine light.
- Park vehicle and set the emergency brakes.
- Locate the OBD-II port under the dashboard.
- Plugin your scanner.
- Turn on the ignition but don’t start the engine. On vehicles with Start/Stop button, press it twice without touching the brake pedal.
- Allow the scanner to turn on and connect to the car.
- Select OBD-II, then READ CODES. Make sure there are no current codes. If the problem has been fixed, only stored codes should be present.
- Go back and select CLEAR FAULT CODES. Press enter.
- Turn off the ignition, wait 10 seconds, and restart the engine. Check engine light should be on.
This procedure should be performed after a repair. If the Lexus check engine light doesn’t turn off, it is because there is a problem that has not been fixed yet.
Clearing Lexus fault codes without fixing the problem is not recommended. The check engine light will come back on immediately or within a few days, depending on the issue.
Check engine light can also be reset by disconnecting the battery for a few minutes.
A check engine can also reset on its own if no fault codes are present. Typically it takes several driving cycles or about 4-5 days for Lexus check engine light to reset on its own.
