Solution

1. Preparation

Tools Required: Multimeter, socket set, screwdriver set, OBD-II scanner.
Disconnect the negative battery terminal to prevent any electrical shorts while working on the vehicle.

2. Battery Inspection and Replacement

Check Battery Voltage:
- Reconnect the multimeter leads to the battery terminals, ensuring a proper connection.
- If the voltage is below 12.4 volts, proceed to replace the battery.
Replace Battery (if necessary):
- Remove the negative terminal first, followed by the positive terminal.
- Unscrew any securing brackets and carefully lift the battery out of the tray.
- Place the new battery in the tray, securing it with brackets.
- Connect the positive terminal first, followed by the negative terminal.
- Test the battery voltage again to confirm proper installation.

3. Ignition Switch and Starter Relay Check

Inspect Ignition Switch:
- With the multimeter set to measure voltage, check the ignition switch output when the key is turned to the start position.
- If no voltage is present, replace the ignition switch.
Test Starter Relay:
- Locate the starter relay in the fuse box.
- Swap it with a similar relay (if available) to check functionality.
- If the starter relay is faulty, replace it with a new one.

4. Fuse Inspection

Check Fuses:
- Locate the fuse box and identify the ignition and starter fuses.
- Remove each fuse and visually inspect for any breaks in the metal strip.
- Replace any blown fuses with the same amperage rating.
