Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, fuse puller.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn on the ignition (do not start the engine).
Follow the scanner prompts to retrieve any stored error codes.
Document any codes for further analysis.

3. Inspect Battery and Charging System

Use a multimeter to check the battery voltage (should be around 12.6 volts when off).
Start the engine and check the voltage again (should be between 13.7 and 14.7 volts).
Clean and tighten battery terminals and inspect for corrosion.

4. Check Fuses

Locate the fuse box (typically under the dashboard or in the engine compartment).
Use a fuse puller to remove and inspect each fuse related to the dashboard and electrical systems.
Replace any blown fuses with the same amperage.

5. Inspect Wiring and Connectors

Visually inspect wiring harnesses and connectors for fraying, breakage, or corrosion.
Repair or replace damaged wiring as necessary.
Ensure all connectors are properly seated and secure.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Turn on the ignition and check if the dashboard lights are still flashing.
If flashing persists, further diagnosis may be needed.
