Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and wire brush.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Sub-step 1: Use the multimeter to check the battery voltage. It should read between 12.4V and 12.7V when the vehicle is off.
Sub-step 2: If the voltage is low, charge the battery fully and retest.
Sub-step 3: Inspect the battery terminals for corrosion. Clean with a wire brush if necessary.

3. Wiring and Connections

Sub-step 1: Visually inspect the wiring harness for fraying or damage. Pay attention to areas near moving parts.
Sub-step 2: Secure any loose connections by tightening connectors and ensuring they are seated properly.
Sub-step 3: If damaged wiring is found, repair or replace the affected wires using appropriate connectors.

4. Fuse Check

Sub-step 1: Open the fuse box and locate the fuses related to the dashboard and interior lights.
Sub-step 2: Remove and inspect each fuse; replace any that are blown with the same amperage rating.
Sub-step 3: Ensure the fuse box cover is securely fastened after inspection.

5. Alternator Assessment

Sub-step 1: Start the vehicle and use the multimeter to check the voltage at the battery with the engine running. It should read between 13.5V and 14.5V.
Sub-step 2: If the voltage is outside this range, consider testing or replacing the alternator.
