Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (screwdrivers, socket set)
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect Battery and Connections

Sub-steps:
1. Remove the battery terminals (negative first, then positive) to avoid any short circuits.
2. Clean any corrosion from the battery terminals using a wire brush.
3. Ensure the connections are tight and secure, then reconnect the battery (positive first, then negative).

3. Check Fuses

Sub-steps:
1. Locate the fuse box (refer to the owner’s manual for the exact location).
2. Inspect all fuses related to the dashboard and electrical systems.
3. Replace any blown fuses with new ones of the same amperage.

4. Test Voltage Output

Sub-steps:
1. With the battery connected, use a multimeter to check the voltage of the battery (should read around 12.6 volts with the engine off).
2. Start the vehicle and check the voltage again (should read between 13.7 to 14.7 volts).
3. If voltage is outside this range, the alternator may need inspection or replacement.

5. Inspect Wiring and Connectors

Sub-steps:
1. Visually inspect wiring harnesses for any fraying, chafing, or damage.
2. Check connectors for corrosion, dirt, or loose connections; clean or tighten as necessary.
3. If any damaged wires are found, repair or replace them.
