  • •Inconsistent deployment of airbags during a crash simulation
  • •Diagnostic tool reporting multiple airbag-related fault codes
  • •Loss of certain safety system functionalities

Diagnostic Steps

  1. 1Scan the vehicle’s ECU using an OBD-II scanner to confirm the B1080 code and check for additional error codes.
  2. 2Inspect the airbag control module connections for any visible damage, corrosion, or loose connections.
  3. 3Check the vehicle’s battery voltage to ensure it is within the normal operating range (12.4V to 12.7V).
  4. 4Verify the integrity of the wiring harness leading to the airbag control module.
  5. 5Perform a reset of the airbag system using the OBD-II scanner and check if the code reappears.

Solution

Solution

1. Preparation

  • Ensure the vehicle is parked on a level surface and the ignition is OFF.
  • Disconnect the battery terminals, starting with the negative terminal to prevent any electrical shock.
  • Wait at least 10 minutes to allow capacitors in the airbag system to discharge.

2. Inspect Airbag Control Module

  • Locate the airbag control module, typically found under the center console or near the driver's seat.
  • Remove any covers or panels obstructing access to the control module.
  • Check the connectors for signs of damage or corrosion. Clean connectors with electrical contact cleaner if necessary.
  • Reconnect the module securely.

3. Test Wiring Harness

  • Visually inspect the wiring harness for any signs of fraying or breaks.
  • Use a multimeter to check continuity of wires leading to the airbag control module.
  • Repair any damaged wires by splicing in new wire, ensuring proper insulation to prevent short circuits.

4. Reconnect Battery and Clear Codes

  • Reconnect the battery terminals, starting with the positive terminal.
  • Use the OBD-II scanner to clear the B1080 code and any other airbag-related codes.
  • Ensure the airbag warning light does not re-illuminate after clearing.

5. Testing and Final Checks

  • Perform a test drive to ensure all systems function properly.
  • Monitor the airbag warning light to confirm it remains off and no new codes appear.

Verification

After completing the repair, verify that the issue has been resolved:

  • Test the affected component to ensure it functions correctly
  • Check for any error codes or warning lights
