1. Put the key in the ignition and turn it to the "On" position, but don't start the engine.
2. Locate the Diagnostic Link Connector (DLC) under the dashboard, typically near the driver's side footwell.
3. Using a wire or a jumper, connect the +B (positive battery) and CG (check ground) terminals on the DLC.
4. Watch for the airbag light to start blinking. Count the blinks carefully – there might be a series of quick blinks followed by a longer pause.
5. Once you've counted the blinks, turn the ignition switch off and disconnect the wire or jumper from the DLC.
6. Refer to the table below to decipher the airbag light blink codes and identify the specific issue triggering the light.
7. If the light continues to blink after performing the reset or if you're unsure how to interpret the codes, take your vehicle to a qualified Toyota dealership or mechanic for further diagnosis and repair.
