Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, fuse puller, basic socket set, battery terminal cleaner.
Ensure the vehicle is parked on a flat surface, and the engine is turned off. Disconnect the negative battery terminal before starting work on electrical components.

2. Battery Inspection

Remove the battery terminal covers.
Clean any corrosion from the battery terminals using a battery terminal cleaner.
Tighten the connections to ensure a solid contact.

3. Fuse Replacement

Locate the fuse panel, typically found under the dashboard or in the engine compartment.
Use a fuse puller to remove any blown fuses.
Replace with new fuses of the same amperage rating (check the diagram on the fuse panel cover).

4. Ground Connection Repair

Locate all ground wires connected to the chassis and engine.
Disconnect ground wires and clean the contact points.
Reattach the ground connections securely.

5. Battery Load Testing

Connect the multimeter to the battery terminals, set to voltage mode.
Perform a load test using a dedicated battery load tester.
Replace the battery if it fails to hold voltage under load (below 9.6 volts).
