Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent accidental deployment of the airbags.
Allow the vehicle to sit for at least 10 minutes to ensure all systems discharge.

2. Inspect and Repair Wiring

Tools Required: Multimeter, wire stripper, electrical tape
Check the wiring harness connected to the airbag control module for any loose connections or frays.
If any damage is found, repair the wiring by stripping the insulation and using solder or butt connectors to reconnect the wires.
Wrap the repaired areas with electrical tape to prevent future exposure.

3. Replace Airbag Control Module (if necessary)

Tools Required: Socket set, torque wrench
If diagnostics indicate a faulty airbag control module, remove it by unscrewing the mounting bolts.
Disconnect the electrical connectors from the module.
Install the new control module by reversing the removal steps and ensuring all connections are secure.
Torque the mounting bolts to the manufacturer’s specifications (specify exact torque values if available).

4. Reconnect Battery and Test System

Reconnect the negative battery terminal.
Start the vehicle and check if the airbag light remains illuminated. If it is off, the repair is likely successful.
