Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, fuse puller, wire brush, electrical contact cleaner.
Safety Warnings: Disconnect the battery before working on electrical systems to avoid shorts or shocks.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative terminal of the battery.
2. Clean the battery terminals with a wire brush to remove any corrosion.
3. Reconnect the terminals tightly and ensure there is no movement.

3. Fuse Check and Replacement

Sub-steps:
1. Locate the fuse box and open it.
2. Identify the fuses related to the malfunctioning components.
3. Use a fuse puller to remove any blown fuses.
4. Replace blown fuses with new ones of the same amperage rating.

4. Wiring Inspection

Sub-steps:
1. Inspect visible wiring harnesses under the dashboard and engine bay for any frays or cuts.
2. If damage is found, use electrical tape to secure minor issues or replace the harness for severe damage.

5. Ground Connection Testing

Sub-steps:
1. Locate the ground points in the vehicle (commonly found on the chassis).
2. Remove the ground bolt, clean the connection area with a wire brush, and reattach the ground securely.
