Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, wire brush, safety gloves, and safety glasses.
• Ensure the vehicle is parked on a flat surface, and the engine is turned off.

2. Battery Inspection

• Sub-step 1: Disconnect the negative terminal of the battery to prevent electrical shorts.
• Sub-step 2: Clean the battery terminals using a wire brush to remove any corrosion.
• Sub-step 3: Reconnect the battery terminals, ensuring they are tight and secure.

3. Fuse and Wiring Check

• Sub-step 1: Locate the fuse box (usually under the dashboard or in the engine compartment) and check for blown fuses.
• Sub-step 2: Replace any blown fuses with the correct amperage rating.
• Sub-step 3: Inspect wiring harnesses for frays or loose connections and repair as necessary.

4. Alternator Testing

• Sub-step 1: Reconnect the battery and start the engine.
• Sub-step 2: Measure the voltage at the battery terminals with the engine running using a multimeter.
• Sub-step 3: If voltage is below 13.5V, consider replacing the alternator.

5. Final Steps

• Sub-step 1: Clear any error codes using the OBD-II scanner and test drive the vehicle to check for the return of flashing lights.
• Sub-step 2: Monitor the dashboard for any recurring issues.
