Solution

1. Preparation

Tools Required:
- Multimeter
- Wrench set
- Screwdriver set
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative battery cable using a wrench.
2. Inspect the battery for any signs of leakage or swelling; replace if necessary.
3. Clean the battery terminals with a wire brush to remove corrosion.
4. Reconnect the battery cables, ensuring they are tight.

3. Starter Motor Check

Sub-steps:
1. Locate the starter motor, usually found on the lower side of the engine near the transmission.
2. Disconnect the electrical connectors from the starter motor.
3. Use a multimeter to test for voltage at the starter solenoid terminal when the key is turned to the start position.
4. If no voltage is present, the ignition switch may need replacement; if voltage is present and the starter does not engage, replace the starter motor.

4. Ignition Switch Inspection

Sub-steps:
1. Remove the plastic cover around the steering column using a screwdriver.
2. Locate the ignition switch and check for any loose connections or damage.
3. Use a multimeter to test continuity in the ignition switch; replace if faulty.

5. Reassembly

Sub-steps:
1. Reattach any components or covers removed during the inspection.
2. Ensure all electrical connections are tight and secure.
3. Test the vehicle by turning the key to start.
