Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery and allow it to sit for at least 10 minutes to discharge any residual power.
Ensure you have personal protective equipment (PPE) such as gloves and safety glasses.

2. Address Fault Codes

Connect the OBD-II scanner and clear any stored fault codes.
Refer to the vehicle service manual for specific codes and required fixes if codes return after clearing.

3. Inspect and Repair Wiring

Remove any necessary trim panels to access the wiring harness for the SRS.
Visually inspect for any frayed wires, loose connections, or corrosion.
Repair or replace damaged wiring as needed, ensuring proper gauge and insulation.

4. Replace Faulty Components

If specific components are identified as faulty (e.g., crash sensors, seatbelt tensioners), remove them.
Install new parts according to manufacturer specifications, ensuring all connections are secure.
Torque any bolts to the specified values provided in the service manual.

5. Final Check

Reconnect the vehicle battery.
Perform a system check using the OBD-II scanner to ensure all fault codes are cleared.
Conduct a final visual inspection of the SRS components to ensure everything is correctly installed.
