How do I reset Ls400 check airbag light?

To reset the airbag light on a Lexus LS400, first, ensure that the vehicle's ignition is turned off. Then, locate the diagnostic connector, usually found under the dashboard, and use a jumper wire to connect terminals TE1 and E1. Turn the ignition on without starting the engine; the airbag light will blink to indicate the reset is in progress. After a few seconds, remove the jumper wire, turn off the ignition, and then start the vehicle to check if the light has reset. If the light remains on, there may be an underlying issue that needs professional diagnosis.
