If damaged, repair or replace the affected wiring or connectors.

4. Replace Faulty Crash Sensors

Locate the crash sensors (typically found in the front and rear bumpers).
Remove any mounting bolts and disconnect the wiring harness.
Replace with new sensors and reconnect the wiring.

5. Repair or Replace Seatbelt Pretensioners

Remove the seat covers to access the pretensioners if necessary.
Inspect for any signs of damage; if faulty, replace the pretensioners.
Reinstall the seat covers securely after repairs.

6. Reconnect Battery and Clear Codes
