Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and wiring harness repair tools.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Battery and Connections

Remove the battery terminals (negative first, then positive).
Clean any corrosion from the terminals and battery posts.
Ensure connections are tight and reinstall the terminals (positive first, then negative).

3. Test Battery and Alternator

Reconnect the battery and use a multimeter to measure the battery voltage with the engine off (should be around 12.6 V).
Start the engine and measure voltage again (should be between 13.7 V and 14.7 V). If not, the alternator may need to be replaced.

4. Check Wiring and Fuses

Remove the dashboard cover to access the wiring harness.
Inspect for damaged wires or loose connections and repair as necessary.
Check the fuse box for any blown fuses related to the dashboard and replace them if necessary.

5. Inspect Ground Connections

Locate the ground points for the dashboard components and ensure they are clean and secure.
Tighten any loose screws or bolts and clean the contact points.
