Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery and wait for at least 10 minutes to ensure that all systems are powered down before working on the SRS system.

2. Inspect and Repair Wiring

Tools Required: Multimeter, socket set, screwdriver set
Carefully remove the driver and passenger seat by unscrewing the bolts securing them to the floor.
Lift the seats and inspect the wiring harnesses beneath for frayed wires or loose connections.
Use a multimeter to test for continuity in the wiring. Repair or replace any damaged wires.

3. Replace Faulty Components

If a specific fault code indicates a defective airbag or seatbelt pretensioner:
- Tools Required: Torx socket set
- Remove the defective airbag or pretensioner by unbolting it from its mounting location.
- Install the new component and torque it to the manufacturer’s specifications (usually around 7-10 ft-lbs for airbags).

4. Reconnect and Test

Reconnect all wiring harnesses securely.
Reinstall the seats and ensure all bolts are tightened.
Reconnect the negative battery terminal and turn on the ignition to check if the SRS light is off.
