Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent accidental deployment of the airbags.

2. Inspect and Replace Airbag Fuses

Locate the fuse box using the owner’s manual.
Remove the airbag fuses one at a time and inspect them for continuity.
Replace any blown fuses with new ones of the same amperage.

3. Check and Repair Wiring Connections

Remove the trim panels to access the airbag connectors.
Inspect the connectors for corrosion, dirt, or damaged pins.
Clean or repair any damaged wiring using solder and heat-shrink tubing.

4. Test and Replace Airbag Sensor

Disconnect the passenger airbag sensor connector from the vehicle.
Using a multimeter, test the resistance of the sensor according to the specifications in the service manual.
If the sensor is faulty, replace it with a new one.
Reconnect the sensor.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use an OBD-II scanner to clear any stored airbag error codes.
Ensure all connections are secure and check for proper operation of the airbag system.
