Repair Instructions

Clearing Codes:
- After diagnosing and resolving the fault, clear the DTCs using the OBD-II scanner.
- Turn the ignition off and then back on to ensure the airbag light resets.
Replacing Faulty Sensors:
- If any airbag sensors are found to be faulty:
  - Disconnect the battery negative terminal for safety (wait at least 10 minutes).
  - Remove the faulty sensor (document the location and orientation).
  - Install the new sensor and reconnect the wiring harness.
  - Reconnect the battery and clear the codes.
Repairing Wiring Issues:
- For damaged wiring:
  - Cut out the damaged section and splice in a new section of wire.
  - Use heat shrink tubing or electrical tape to secure the repair.
  - Re-test the system.
Replacing the Airbag Control Module:
- If the control module is defective:
  - Disconnect the negative battery terminal.
  - Remove the control module from its mounting location.
  - Install the new module and ensure all connections are secure.
  - Reconnect the battery and check for codes.
Seatbelt Tensioner Replacement:
- If the tensioner is faulty:
  - Disconnect the battery.
  - Remove the seatbelt assembly or tensioner from its mounting point.
  - Install the new tensioner, ensuring all connections are tight.
  - Reconnect the battery and clear codes.

Final Steps

After all repairs are made, perform a final diagnostic scan to ensure no DTCs remain.
Test the airbag system by simulating an accident scenario (if safe to do so) to ensure proper deployment.
Always refer to the manufacturer’s service manual for specific torque specifications and detailed procedures.
