Solution

1. Preparation

Gather necessary tools such as an OBD-II scanner, multimeter, and basic hand tools.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery if working on electrical components for safety.

2. Resolve Specific Warning Light Issues

A. Check Engine Light

Connect the OBD-II scanner to the vehicle's diagnostic port.
Record any trouble codes and investigate their meanings.
Clear the codes and monitor if the light reappears after driving.

B. Oil Pressure Warning Light

Check the engine oil level using the dipstick.
If low, top off with the manufacturer's recommended oil type.
If the light remains on, inspect the oil pressure sending unit and engine oil pump for functionality.

C. Battery/Charging System Light

Use a multimeter to check the battery voltage (should be around 12.6V with the engine off).
Start the engine and check the voltage again (should be between 13.7V to 14.7V).
If readings are out of range, inspect the alternator and battery connections for corrosion or damage.

3. Final Checks

Reconnect the battery if it was disconnected.
Start the vehicle and observe the dashboard for any remaining warning lights.
Ensure all systems are functioning correctly before concluding the repair.
