Allow the vehicle to sit for at least 10 minutes after disconnecting the battery to ensure all systems are powered down.

2. Inspect and Repair Wiring

Sub-step 1: Remove the driver's side lower dash panel to access the airbag wiring and connectors.
Sub-step 2: Visually inspect the wiring for any frays or breaks, paying close attention to the connectors.
Sub-step 3: If any damage is found, repair the wiring using appropriate soldering techniques or replace the harness as necessary.
Tools Required: Screwdriver set, wire strippers, soldering iron (if needed).

3. Replace Airbag Module (if necessary)

Sub-step 1: If the airbag squib resistance is out of specification, remove the driver's side airbag by unscrewing it and carefully disconnecting the electrical connector.
Sub-step 2: Install a new airbag module by connecting the electrical connector and securing it with screws.
Tools Required: Torque wrench (if applicable for airbag mounting), socket set.

4. Reconnect Battery and Clear Codes

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Use the OBD-II scanner to clear the B0110 code and any other related codes from the airbag system.
Sub-step 3: Conduct a visual check to ensure all panels are securely re-installed.
