Solution

1. Preparation

Gather necessary tools and parts, ensuring you have an OBD-II scanner, multimeter, and basic hand tools.
Disconnect the negative battery terminal and allow the vehicle to sit for at least 10 minutes to discharge any residual power.

2. Inspect and Repair Wiring

Sub-steps:
1. Remove the underdash panel to access the SRS wiring harness.
2. Inspect the wiring for frays, cuts, or corrosion. Pay special attention to connectors.
3. If damage is found, repair the wiring using solder and heat shrink tubing or replace the wiring harness as necessary.

3. Replace Faulty Components

Sub-steps:
1. If any SRS components (e.g., airbag module, seatbelt pretensioner) are faulty as indicated by diagnostic trouble codes, remove them.
2. Install new components, ensuring they are correctly aligned and securely fastened.
3. Connect all wiring harnesses and ensure proper connections to prevent electrical faults.

4. System Reset and Testing

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use the OBD-II scanner to reset the SRS system.
3. Perform a system self-check to confirm all components are functioning and the SRS warning light is off.
