Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and cleaning materials.
Ensure the vehicle is parked on a flat surface, and the engine is turned off.

2. Battery Inspection

Step 1: Disconnect the negative terminal of the battery.
Step 2: Clean the battery terminals and cables using a wire brush.
Step 3: Reconnect the terminals securely after cleaning.

3. Alternator Testing

Step 1: Start the engine and set the multimeter to DC voltage.
Step 2: Measure voltage at the battery terminals; it should read between 13.7 to 14.7 volts.
Step 3: If the voltage is low, replace the alternator.

4. Ground Connection Inspection

Step 1: Locate and inspect the main ground strap connecting the battery to the chassis.
Step 2: Clean the connection points and ensure the strap is tightly secured.
Step 3: If damaged, replace the ground strap.

5. Fuse Inspection

Step 1: Open the fuse box and visually inspect for any blown fuses.
Step 2: Replace any blown fuses with the correct amperage rating.
Step 3: Ensure the fuse box cover is replaced securely.
