Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Error Code Resolution

Sub-steps:
1. Connect the OBD-II scanner to the vehicle's diagnostic port.
2. Retrieve and note all error codes.
3. Refer to the service manual to diagnose the issues associated with each code.
4. Clear the codes and observe if they return after a test drive.

3. Fluid Level Check and Top-Up

Sub-steps:
1. Open the hood and check oil, coolant, brake fluid, and transmission fluid levels.
2. If any fluid is low, top it up with the manufacturer-recommended fluids.
3. Recheck the dashboard for warning lights after ensuring fluid levels are correct.

4. Battery Inspection

Sub-steps:
1. Inspect battery terminals for corrosion or loose connections.
2. Clean terminals with a wire brush if necessary.
3. Use a multimeter to test the battery voltage; it should read between 12.4V to 12.7V.
4. Replace the battery if it fails to hold charge or shows low voltage.

5. Sensor and Fuse Checks

Sub-steps:
1. Locate the fuse box and inspect related fuses for the dashboard warning lights.
2. Replace any blown fuses with the correct amperage.
3. Check the condition of relevant sensors; replace faulty sensors as needed.
