Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery and Connections

Tools Required: Socket set, multimeter
Inspect the battery terminals for corrosion and clean if necessary using a wire brush.
Check the battery voltage with a multimeter. If below 12.4 volts, replace the battery.

3. Fuse Inspection

Tools Required: Fuse puller or needle-nose pliers
Remove the fuse box cover and identify the fuses related to the affected systems.
Replace any blown fuses with the correct amperage (refer to the owner's manual for specifics).

4. Ground Connection Check

Tools Required: Socket set, multimeter
Locate ground points (usually near the battery and on the chassis).
Remove ground connections, clean the contact points, and reattach securely.

5. Wiring Inspection

Tools Required: Multimeter, screwdriver set
Inspect wiring harnesses visually for wear, fraying, or damage.
Use a multimeter to check for continuity in suspect wiring. Repair or replace damaged sections as necessary.

6. System Testing

Reconnect the battery and perform a system reset if necessary.
Recheck for any error codes using the OBD-II scanner.
Test the previously malfunctioning electrical components to verify functionality.
