Solution

1. Preparation

Tools Required: Multimeter, socket set, wrench set, OBD-II scanner, cleaning brush.
Ensure the vehicle is in park or neutral and the parking brake is engaged. Disconnect the negative battery terminal.

2. Battery Inspection and Replacement

Inspect the Battery: Use the multimeter to check the voltage. If it reads below 12.4 volts, consider charging or replacing the battery.
Clean Terminals: If corrosion is present, clean the terminals and cable ends using a wire brush.
Reconnect Battery: Reconnect the battery terminals tightly, ensuring no corrosion is present.

3. Starter Motor Check

Access Starter Motor: If necessary, remove any components obstructing access to the starter motor.
Test Voltage at Starter: While someone turns the key to the start position, measure voltage at the starter motor. It should be around 12 volts.
Replace Starter if Necessary: If there is no voltage or the starter is malfunctioning, replace it with a new unit.

4. Fuse Inspection

Locate Fuse Box: Find the fuse box and remove the panel cover.
Check Starter Fuse: Identify and remove the starter fuse. Use a multimeter to test for continuity.
Replace Fuses if Required: If blown, replace with the same amperage rating.
