Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wire brush, electrical contact cleaner.
Safety Warnings: Disconnect the negative battery terminal before working on any electrical components.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the negative battery terminal using a socket wrench.
2. Inspect the battery for corrosion or damage; clean terminals with a wire brush and electrical contact cleaner if necessary.
3. If the battery is weak (below 12.4 volts), replace it with a new one following the manufacturer's specifications.

3. Fuse Inspection and Replacement

Sub-steps:
1. Locate the fuse box (consult the owner’s manual for location).
2. Remove each fuse related to the malfunctioning systems and check for continuity with a multimeter.
3. Replace any blown fuses with the correct amperage rating as specified in the owner’s manual.

4. Wiring Inspection and Repair

Sub-steps:
1. Inspect wiring harnesses for any visible damage or wear.
2. Repair or replace any damaged wires using heat-shrink tubing and electrical tape for insulation.
3. Ensure all connectors are securely fastened and free from corrosion.

5. Ground Connection Check

Sub-steps:
1. Locate ground points, typically near the battery and engine block.
2. Remove the ground bolts, clean the contact area, and reattach them securely.
3. Confirm that all grounds are tight and free of rust or contamination.
