Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and wrench set.
Ensure the vehicle is in park and the ignition is off.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection

Inspect Battery Terminals:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion using a wire brush and a solution of baking soda and water.
- Reconnect the battery terminals, ensuring they are tight.
Test Battery Voltage:
- Reconnect the negative terminal.
- Use a multimeter to measure the battery voltage. If it is below 12.4 volts, consider charging or replacing the battery.

3. Starter Relay and Ignition Switch

Test Starter Relay:
- Locate the starter relay in the fuse box.
- Swap it with another relay of the same type to see if the clicking noise persists.
Inspect Ignition Switch:
- Remove the steering column cover if necessary.
- Check for wear or damage on the ignition switch and ensure it engages when turned.

4. Starter Motor Inspection

Check Wiring Connections:
- Locate the starter motor and inspect the wiring harness for any loose connections or damage.
- Tighten or repair any loose or damaged connections.
Test Starter Motor:
- If the issue persists, remove the starter motor for bench testing. Use a jumper cable to connect directly to the battery to see if the motor engages.
