Solution

1. Preparation

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

2. Address Error Codes

Sub-step 1: Clear the DTCs using the OBD-II scanner.
Sub-step 2: Reconnect the battery and start the engine to see if warning lights reappear.

3. Fluid Levels Correction

Sub-step 1: If low, top off engine oil, coolant, brake fluid, and transmission fluid using manufacturer-recommended fluids.
Sub-step 2: Check for leaks that might have caused fluid loss.

4. Battery Maintenance

Sub-step 1: Clean battery terminals with a wire brush to remove corrosion.
Sub-step 2: If the voltage is low (below 12.4V), consider charging or replacing the battery.

5. Wiring and Connectors Inspection

Sub-step 1: Inspect wiring harnesses for fraying or damage and repair or replace as necessary.
Sub-step 2: Ensure all connectors are secure and free from corrosion.

6. System Tests

Sub-step 1: Test the alternator output with a multimeter; it should read between 13.7V and 14.7V when the engine is running.
Sub-step 2: If issues persist, replace malfunctioning sensors or components based on the DTCs retrieved.
