Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical shorts.

2. Addressing Check Engine Light

Tools Required: OBD-II scanner, socket set, screwdrivers.
Retrieve codes from the OBD-II scanner.
Research the codes to identify faulty sensors or systems.
Replace or repair the identified components as necessary, such as oxygen sensors or catalytic converters.

3. Brake Warning Light

Tools Required: Brake fluid tester, socket set.
Check the brake fluid reservoir for low fluid levels; refill with the manufacturer-recommended fluid if necessary.
Inspect brake pads and rotors for wear; replace if needed.
Test the brake system for leaks.

4. Tire Pressure Monitoring System (TPMS)

Tools Required: Tire pressure gauge, air compressor.
Measure the tire pressures using the tire pressure gauge.
Inflate tires to the recommended PSI.
If the TPMS warning persists, reset the system according to the owner's manual.

5. ABS System Check

Tools Required: Diagnostic scanner.
Use a diagnostic scanner to check ABS fault codes.
Inspect ABS sensors and wiring for damage; clean or replace as necessary.
