Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle battery to ensure safety while working on the electrical components.
Allow the vehicle to sit for at least 10 minutes to ensure that any residual power is discharged.

2. Inspect and Repair Wiring

Tools Required: Multimeter, wire strippers, electrical tape
Inspect the wiring harness leading to the pretensioner for fraying or damage.
If damage is found, cut out the damaged section and splice in new wiring using wire connectors.
Secure connections with electrical tape and ensure proper insulation.

3. Replace Faulty Pretensioner

Tools Required: Socket set, torque wrench
Locate the pretensioner unit, typically attached to the seatbelt assembly.
Remove the mounting bolts using the socket set and carefully detach the pretensioner from the seat frame.
Install the new pretensioner in reverse order, ensuring it is secured tightly to the frame.
Torque the bolts to the manufacturer's specified torque value (consult service manual for exact specification).

4. Reconnect Battery and Clear Codes

Reconnect the vehicle battery and ensure all connections are secure.
Use the OBD-II scanner to clear any stored error codes from the system.
Confirm that the seatbelt warning light is extinguished.
