Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, wrench set, screwdriver set, jumper cables.
Ensure the vehicle is parked on a flat surface and the ignition is off. Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Sub-steps:
1. Reconnect the battery terminal if it was disconnected.
2. Check battery voltage again; if below 12.4 volts, charge or replace the battery.
3. Clean the battery terminals using a wire brush and a mixture of baking soda and water to remove corrosion.

3. Fuse Inspection

Sub-steps:
1. Locate the fuse box (usually under the dashboard or in the engine compartment).
2. Remove and visually inspect the fuses related to the ignition and starting system.
3. Replace any blown fuses with ones of the same amperage rating.

4. Starter Motor Testing

Sub-steps:
1. Locate the starter motor, typically near the transmission.
2. Use jumper cables to connect the starter motor directly to the battery.
3. If the starter engages and spins, it is functioning; if not, replace the starter motor.

5. Neutral Safety Switch Inspection

Sub-steps:
1. Locate the neutral safety switch (usually on the transmission).
2. Check the switch operation by shifting the vehicle into neutral and attempting to start.
3. If the vehicle starts in neutral, the switch may need adjustment or replacement.
