Solution

1. Preparation

Gather tools: OBD-II scanner, basic hand tools (screwdrivers, sockets), and a multimeter.
Ensure the vehicle is parked on a flat surface with the ignition off.
Disconnect the 12V battery to prevent accidental airbag deployment.

2. Inspect and Repair Wiring

Sub-steps:
1. Remove the relevant trim pieces to access the airbag module and wiring harness.
2. Visually inspect all wiring for signs of wear, fraying, or damage.
3. Use a multimeter to test continuity in the wire harness.
4. Repair any damaged wires by splicing new wire sections and covering with heat-shrink tubing.

3. Replace Airbag Module (if necessary)

Sub-steps:
1. If codes indicate a faulty airbag module, carefully disconnect the module from the wiring harness.
2. Remove the module by unbolting it from its mounting location.
3. Install the new airbag module, ensuring all connections are secure.
4. Reconnect the battery.

4. Clear Error Codes

Sub-steps:
1. Reconnect the OBD-II scanner to the vehicle.
2. Clear any stored error codes in the SRS system.
3. Disconnect the scanner after clearing codes.

5. Final Assembly

Sub-steps:
1. Reinstall any trim pieces that were removed during the inspection and repair process.
2. Ensure all tools are removed from the vehicle.
