Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, torque wrench, basic hand tools, and a wiring diagram for the airbag system.
• Disconnect the vehicle's battery and wait at least 10 minutes before working on the airbag system to ensure safety.

2. Inspect Wiring and Connectors

• Remove the passenger seat to access the airbag harness and connectors.
• Inspect all connectors for corrosion or damage; clean or replace as necessary.
• Check the wiring for any signs of fraying or breaks, particularly where the wires bend.

3. Test the Weight Sensor

• Locate the passenger seat weight sensor beneath the seat.
• Disconnect the sensor and use a multimeter to test for continuity and correct voltage supply.
• If the sensor is faulty, replace it with a new one, ensuring it is properly calibrated.

4. Inspect Airbag Module

• Remove the airbag module from its mounting location, taking care to follow safety protocols.
• Check for any signs of physical damage or moisture inside the module.
• If damaged, replace the airbag module with a new OEM part.

5. Reassemble and Reconnect

• Reconnect all connectors and wiring, ensuring a secure fit.
• Reinstall the passenger seat and any trim pieces removed during the process.
• Reconnect the vehicle's battery.

6. Clear Codes and Test

• Use the OBD-II scanner to clear any existing codes.
• Perform a self-test of the airbag system to verify that the B0030 code does not return.
