what does the B0080 code indicate for my Volvo XC90 Second Generation (2015-2024)

Solution

1. Preparation

• Ensure the vehicle is parked on a flat surface and the ignition is off.
• Disconnect the negative battery terminal and wait at least 10 minutes to allow any residual energy to dissipate.

2. Inspect and Repair Wiring

• Tools Required: Wiring diagram for the airbag system, multimeter, electrical tape.
• Inspect the wiring harness connected to the airbag module and passenger airbag for any frays, corrosion, or disconnections.
• Use a multimeter to check for continuity in the wiring. Repair any damaged wires by splicing in new wire and securing with electrical tape.

3. Replace Airbag Module (if necessary)

• Tools Required: Socket set, torque wrench, T30 Torx driver.
• Locate the airbag module, which is typically found under the center console or behind the dashboard.
• Remove any panels or covers to access the module.
• Disconnect the wiring harness from the module and remove the mounting bolts using the socket set.
• Install the new airbag module, ensuring it is properly aligned and secure, then reconnect the wiring harness.
• Torque the mounting bolts to manufacturer specifications.

4. Verify Passenger Occupant Sensor

• Tools Required: None.
• Check the passenger seat occupant sensor for proper operation. Make sure it is functioning correctly and that there are no obstructions.
• If the sensor is defective, replace it according to the manufacturer's guidelines.

5. Reconnect Battery and Clear Codes

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear the B0080 code and any other related codes.
• Start the vehicle and check that the airbag warning light is off.
