Solution

1. Preparation

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

2. Addressing Check Engine Light

Sub-steps:
1. Connect the OBD-II scanner and retrieve the error codes.
2. Research the codes to determine the necessary repairs (e.g., replace oxygen sensor, fix vacuum leaks).
3. Perform the required repairs based on the diagnostic codes.

3. Resolving Brake Warning Light

Sub-steps:
1. Check the brake fluid reservoir and top off if low.
2. Inspect brake lines and components for leaks or damage.
3. If brakes are worn, replace brake pads and/or rotors as needed.

4. Fixing Oil Pressure Warning Light

Sub-steps:
1. Check the oil level and add oil if low; ensure the correct type is used (e.g., 0W-20).
2. Inspect the oil filter for leaks and replace if necessary.
3. Replace the oil pressure sending unit if the issue persists.

5. Addressing Battery Warning Light

Sub-steps:
1. Test the battery voltage with a multimeter; it should read around 12.6 volts when fully charged.
2. Clean battery terminals and ensure they are securely connected.
3. If the battery is weak, replace it with a new one.

6. Tire Pressure Monitoring Light

Sub-steps:
1. Check the tire pressures using a tire gauge and inflate to the recommended PSI.
2. Reset the TPMS using the vehicle settings menu or by driving the vehicle for a short distance.
3. Replace any faulty TPMS sensors if the light remains on after resetting.
