Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (or neutral for manual) and the ignition is off.
Disconnect the negative terminal of the battery to ensure safety.

2. Battery Inspection

1.1 Check battery voltage: Connect the multimeter leads to the battery terminals; a healthy battery should read around 12.6 volts.
1.2 Clean terminals: Use a battery terminal cleaner or a wire brush to remove corrosion from the battery terminals.
1.3 Tighten connections: Ensure that both the positive and negative terminals are secure.

3. Starter Relay Testing

2.1 Locate the starter relay in the fuse box (refer to the owner’s manual for exact location).
2.2 Remove the relay and test it using a multimeter for continuity.
2.3 Replace the relay if it shows no continuity or is faulty.

4. Ignition Switch Check

3.1 Locate the ignition switch, typically found on the steering column.
3.2 Disconnect the wiring harness from the ignition switch.
3.3 Use a multimeter to test the switch for continuity in both the 'on' and 'start' positions.
3.4 Replace the ignition switch if it fails the continuity test.

5. Reassemble and Test

4.1 Reconnect the battery terminals.
4.2 Start the vehicle to check if the engine turns over.
