Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and a wiring diagram.
Ensure the vehicle is in a safe location with the ignition off and the battery disconnected.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Read and document any error codes; research their meanings for further diagnosis.

3. Inspect and Replace Fuses

Locate the fuse box according to the owner’s manual.
Use a fuse puller to remove and inspect each fuse related to the malfunctioning components.
Replace any blown fuses with the correct amperage rating.

4. Check and Test the Battery

Use a multimeter to measure the battery voltage (should be around 12.6 volts when fully charged).
If the voltage is low, charge the battery or replace it if it cannot hold a charge.

5. Inspect Wiring and Connections

Visually examine wiring harnesses for any signs of wear, fraying, or corrosion.
Tighten any loose connections and clean any corroded terminals with a wire brush and electrical cleaner.

6. Test Electrical Components

For each component that is not functioning, disconnect it and test with a multimeter for continuity.
Replace any faulty components as determined by testing.

7. Verify Ground Connections

Identify all ground points in the vehicle and ensure they are clean and securely fastened.
Use a multimeter to check for continuity between ground points and the chassis.
