Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the negative battery terminal to prevent accidental deployment of the airbags.

2. Inspect and Repair Wiring

Tools Required: Multimeter, wire connectors, electrical tape
Inspect the wiring harness for any frays, shorts, or disconnections.
Use the multimeter to check for continuity in the airbag circuits.
Repair any damaged wires by cutting out the damaged section and splicing in new wire using proper connectors.
Secure connections with electrical tape to prevent moisture ingress.

3. Check and Replace Airbag Module (if necessary)

Tools Required: Socket set, ratchet
Locate the airbag module under the center console or dashboard.
Remove the mounting bolts using a socket set and carefully disconnect the wiring harness from the module.
If the module shows signs of damage or if error codes indicate a faulty module, replace it with a new, compatible airbag module.
Reconnect the wiring harness and securely mount the module back in place.

4. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored airbag fault codes.
Verify that the airbag light on the dashboard is no longer illuminated.
