Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, wire brush, dielectric grease.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent accidental deployment of airbags.

2. Clear Diagnostic Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note any DTCs related to the SRS system.
Clear the codes using the scanner.
Reconnect the negative battery terminal, and then start the vehicle to check if the SRS light remains off.

3. Inspect and Repair Connections

Remove the front seats if necessary to access the seatbelt buckle and airbag connectors.
Check the seatbelt connector: Ensure it is securely connected and free from debris.
Clean the connectors with a wire brush and apply dielectric grease to prevent corrosion.

4. Check the Airbag Module

Locate the airbag module, typically under the center console or in the dashboard.
Ensure all connections are secure and inspect the module for signs of damage.
If necessary, replace the airbag module following manufacturer specifications for torque values and installation procedures.

5. Test the Crash Sensor

Locate the crash sensor, usually mounted near the front bumper.
Use a multimeter to test the sensor according to manufacturer specifications.
If faulty, replace the crash sensor and ensure to torque the mounting bolts to the specified value.
