What causes the SRS light to come on in a 2003 Lexus RX 300?

The SRS (Supplemental Restraint System) light in a 2003 Lexus RX 300 can illuminate due to issues with the airbag system, such as a malfunctioning airbag sensor, a faulty seatbelt buckle, or a problem with the wiring. It may also be triggered by a disconnected or damaged airbag module. If the light is on, it indicates that the airbag system may not deploy in the event of an accident, so it’s important to diagnose and address the issue promptly. A professional scan tool can help identify the specific fault triggering the SRS light.
