Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and electrical contact cleaner.
Ensure the vehicle is parked on a flat surface and the engine is off before starting work.

2. Battery Inspection

Sub-step 1: Disconnect the negative terminal of the battery to prevent electrical shock.
Sub-step 2: Inspect battery terminals for corrosion. Clean them with a wire brush and apply anti-corrosion spray if needed.
Sub-step 3: Reconnect the negative terminal securely.

3. Alternator Testing

Sub-step 1: Start the engine and use a multimeter to measure the voltage at the battery terminals. It should read between 13.7 to 14.7 volts.
Sub-step 2: If voltage is low, check the alternator connections and replace the alternator if faulty.

4. Wiring Inspection

Sub-step 1: Visually inspect the wiring harness connected to the dashboard for any signs of damage or loose connections.
Sub-step 2: Repair or replace any damaged wiring or connectors as necessary.

5. Fuse Box Inspection

Sub-step 1: Locate the fuse box and remove the cover.
Sub-step 2: Inspect all fuses related to the dashboard and electrical systems for any blown fuses.
Sub-step 3: Replace any blown fuses with the appropriate amperage rating.

6. Ground Connection Check

Sub-step 1: Locate the ground connection point for the dashboard wiring.
Sub-step 2: Ensure it is clean, tight, and free of corrosion. Clean it if necessary and re-secure the connection.
