Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shocks.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Read and record any trouble codes displayed on the scanner.

3. Address Identified Issues

If Check Engine Light Code Indicates a Specific Issue:
- For misfires: Replace faulty spark plugs or ignition coils.
- For sensor issues: Replace defective sensors (e.g., O2 sensor, MAF sensor).
If Transmission Warning Light is On:
- Check transmission fluid level and condition. Replace fluid if necessary.
- Replace any damaged transmission components if codes indicate failure.
If Brake Warning Light is On:
- Inspect brake pads and rotors, replacing them if worn.
- Refill brake fluid if low and check for leaks in the braking system.
If Oil Pressure or Battery Light is On:
- Check and change engine oil and filter if necessary.
- Inspect and replace the battery if testing shows low voltage or poor health.

4. Reassemble and Test

Reconnect the battery.
Clear the error codes using the OBD-II scanner.
Start the engine and ensure all warning lights are extinguished.
