In this guide, you will find step-by-step instructions on how to read and clear Lexus airbag fault codes. This procedure works on 1996 and newer Lexus vehicles including Lexus ES330, IS250, RX300, RX350, etc. 

What you will need

Generic code readers can not access the airbag module and will show no fault codes related to the airbag system. The scanner must be able to diagnose Toyota airbag system (SRS). 

Procedure

  1. Connect your OBD-II diagnostic tool to the diagnostic port located under the dashboard, driver's side.2004-Lexus-ES-330 OBDII port 2013-Lexus-GS-350 diagnostic port2007-Lexus-IS-250 OBDII port2007-Lexus-IS-250 OBD II port

Notes

This procedure can be used to turn off Lexus airbag light. Fault codes should only be cleared after the system has been repaired. Do not clear Lexus airbag codes, if the fault codes status is CURRENT or PRESENT. See further instructions below. 

Clearing Lexus airbag codes without addressing the issue is not recommended. When Lexus airbag light is reset without fixing the underlying problem, the airbag light will come back on when you restart the car.
