Problem overview

Some Lexus RX300 owners report experiencing issues with the SRS (Supplemental Restraint System) light remaining illuminated, which may indicate a potential problem with the airbag system. Common causes include clock spring failure, which often triggers the airbag light, and damaged wiring in the airbag system that can also keep the SRS light on. Additionally, a faulty crash sensor or issues with the passenger weight sensor may lead to the light staying illuminated, signaling a malfunction in the airbag system. In some cases, low battery voltage can trigger the SRS light as well. To address these concerns, owners are advised to diagnose the specific cause of the SRS light, attempt to reset it, and use an OBD-II scanner to read airbag codes. Given the importance of the SRS light as a safety indicator, it is crucial for owners to resolve these issues promptly and consult a professional mechanic or authorized service center if necessary.
