Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is turned off and parked on a flat surface.
Disconnect the negative terminal of the battery to ensure safety during electrical diagnostics.

2. Address Fault Codes

Identify the error codes retrieved from the OBD-II scanner.
Research and determine if the codes are related to specific components or systems.
Clear the error codes and check if they reappear after testing.

3. Battery and Charging System Inspection

Sub-step 1: Measure the main battery voltage using a multimeter. Voltage should be approximately 12.6V (fully charged) or higher.
Sub-step 2: Test the auxiliary battery voltage in a similar manner.
Sub-step 3: Check the charging system by connecting to a charging station and observing charging status and completion.

4. Replace Faulty Fuses and Relays

Identify any blown fuses or damaged relays from the inspection.
Remove and replace with new fuses of the same amperage rating.
Ensure relays are replaced with OEM parts for optimal compatibility.

5. Repair or Replace Wiring and Connectors

Inspect damaged wiring or corroded connectors and repair as necessary.
Use electrical tape or heat-shrink tubing to insulate repaired wires.
Replace any severely damaged wiring harnesses or connectors.

6. Component Testing and Replacement

For any non-functional components, test them individually with a multimeter.
Replace any components that do not function correctly, ensuring to use compatible parts.
