Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Scan and Record 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 error codes for reference.

3. Inspect Battery and Charging System

Use a multimeter to check the battery voltage (should be around 12.6 volts).
Inspect battery terminals for corrosion and tightness; clean if necessary.
Check the alternator output while the engine is running (should be 13.5-14.5 volts).

4. Check and Replace Fuses

Locate the fuse box and use the fuse diagram to identify any blown fuses.
Remove and replace any blown fuses with the appropriate amperage rating.

5. Fluid Check and Top-Up

Open the hood and check the engine oil level using the dipstick; add oil if low.
Inspect coolant level in the reservoir and top up with the recommended coolant.
Check transmission fluid level according to the manufacturer's specifications.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal securely.
Use the OBD-II scanner to clear any diagnostic trouble codes.
Start the engine and observe if warning lights remain illuminated.
