Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, jumper cables.
Safety Warnings: Ensure the vehicle is in park or neutral with the parking brake engaged.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative (-) terminal of the battery to prevent any electrical shorts.
2. Clean the battery terminals using a wire brush and baking soda solution if corrosion is present.
3. Reconnect the battery terminals securely.

3. Starter Motor Test

Sub-steps:
1. Locate the starter motor; it is typically mounted on the engine near the transmission.
2. Disconnect the electrical connector from the starter.
3. Using jumper cables, connect the positive terminal to the starter's positive terminal and the negative terminal to the starter casing.
4. If the starter engages and the engine cranks, the starter motor is functioning and may require further inspection of the ignition circuit.

4. Fuse Inspection

Sub-steps:
1. Consult the owner's manual to locate the fuse box.
2. Remove and visually inspect fuses related to the starter and ignition system.
3. Replace any blown fuses with a fuse of the same amperage.

5. Final Checks

If no issues are found with the battery, starter, or fuses, the ignition switch or the neutral safety switch may need to be inspected or replaced.
