Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical shorts during inspection.

2. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Use a fuse puller to remove and inspect fuses related to the warning lights.
Replace any blown fuses with ones of the same amperage.

3. Inspect Battery and Charging System

Reconnect the battery and use a multimeter to check the battery voltage (should be around 12.6 volts when off and 13.7-14.7 volts when running).
Clean any corrosion from battery terminals and ensure tight connections.
If the voltage is low, consider replacing the battery or checking the alternator for proper operation.

4. Brake System Inspection

Check the brake fluid reservoir; fill with the appropriate brake fluid if low.
Inspect brake lines and components for leaks or damage.
If necessary, bleed the brake system to remove air bubbles.

5. ABS and Traction Control System Inspection

Remove the wheel covers and inspect wheel speed sensors for dirt or damage; clean or replace as needed.
Check the ABS control module connections for corrosion or loose wiring.
If malfunction persists, consider using a diagnostic tool to reset the ABS control module.
