For ABS Light:
- Inspect the wheel speed sensors; clean or replace as necessary.
- Check brake fluid level and top up if low.
For Airbag Light:
- Inspect the connections under the seats and at the airbag module; reconnect or replace faulty connectors.
For TPMS Light:
- Check tire pressures and ensure all tires are inflated to the recommended levels.
- If a tire has a slow leak, repair or replace as needed.

4. Reconnect Battery

If any components were removed, reconnect the vehicle battery.
Ensure all connections are tight to avoid any intermittent issues.

5. Final Check

Start the vehicle and observe if the warning lights remain illuminated.
If the warning lights turn off, the issue may have been resolved.
