Step 1: Locate the fuse box. Typically found under the dashboard or in the engine compartment.
Step 2: Use the vehicle’s manual to identify the airbag fuse and check it for continuity using a multimeter.
Step 3: If the fuse is blown, replace it with a new one of the same amperage.
Step 4: Inspect the connections under the driver and passenger seats. Disconnect the connectors and check for corrosion or loose wires; clean or reconnect as necessary.

3. Clear Error Codes

Step 1: Reconnect the battery negative terminal.
Step 2: Use the OBD-II scanner to connect to the vehicle’s diagnostic port.
Step 3: Retrieve stored codes and note any persistent issues.
