Solution

1. Preparation

Tools Required:
- Multimeter
- Socket set
- Wrench set
- OBD-II scanner
- Battery terminal cleaner
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Replacement

Sub-steps:
1. Disconnect the negative (-) battery cable.
2. Remove the positive (+) cable.
3. Clean the battery terminals with a battery terminal cleaner.
4. Reconnect the cables securely and check for corrosion.
5. If the battery voltage is low (below 12.4V), replace the battery with a new one.

3. Starter Motor and Connections

Sub-steps:
1. Locate the starter motor, typically found near the transmission.
2. Inspect the wiring harness connected to the starter motor for damage.
3. Ensure all connections are tight; repair or replace faulty wiring if needed.
4. If necessary, remove the starter motor by unbolting it from the mounting points and inspect it for internal failure.
5. Replace the starter motor if it is found to be defective.

4. Ignition Switch Check

Sub-steps:
1. Access the ignition switch by removing the steering column cover.
2. Inspect the ignition switch for wear or damage.
3. Use a multimeter to check for continuity in the ignition switch when turned to the "start" position.
4. Replace the ignition switch if it fails to pass the continuity test.
