Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Multimeter
- Socket set
- Torque wrench
- Screwdrivers
Ensure the vehicle is parked on a level surface and the ignition is in the off position.

2. Battery Inspection

Sub-steps:
1. Open the hood and locate the battery.
2. Clean any corrosion from battery terminals using a wire brush and baking soda solution.
3. Tighten the terminal connections to ensure a solid electrical contact.
4. Use a multimeter to check the voltage; replace the battery if below 12.4 volts.

3. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor (typically near where the engine meets the transmission).
2. Disconnect the battery to prevent electrical shock.
3. Inspect wiring and connections to the starter for signs of damage or looseness.
4. Remove the starter motor using the socket set (note torque specifications for reinstallation).
5. Bench test the starter motor by connecting it to a charged battery; if it does not engage, replace it.

4. Ignition Switch Check

Sub-steps:
1. Remove the steering column cover using a screwdriver.
2. Inspect the ignition switch for any visible damage or wear.
3. Test the ignition switch with a multimeter to ensure it is providing continuity when turned to the start position.
4. Replace the ignition switch if it fails the test.

5. Reassembly and Testing

Sub-steps:
1. Reinstall the starter motor and ensure it is properly torqued to specifications.
2. Reconnect the battery terminals securely.
3. Start the vehicle to test for noise and proper operation.
