Solution

1. Preparation

Gather necessary tools: multimeter, OBD-II scanner, socket set, torque wrench, and a hammer.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent any electrical shorts while working.

2. Battery Inspection

1. Inspect the battery terminals for corrosion.
- Clean terminals with a wire brush and a mixture of baking soda and water if corroded.
2. Check the battery cables for any signs of damage or looseness.
- Tighten or replace any damaged cables.

3. Starter Motor Testing

1. Reconnect the battery terminal.
2. Locate the starter motor (typically near the transmission).
3. Test the starter by applying direct voltage to the starter terminal from the battery.
- Ensure proper safety measures are taken to avoid short circuits.
4. If the starter engages, it may need replacement; if not, further testing of the ignition switch is required.

4. Ignition Switch and Relay Inspection

1. Locate the ignition relay in the fuse box and test for continuity.
2. Replace the relay if it shows no continuity.
3. If the relay is functional, inspect the ignition switch for wear or failure.
- Replace the ignition switch if necessary.
