Solution

1. Preparation

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

2. Battery Inspection

Reattach battery terminals: Clean any corrosion using a wire brush, then re-tighten the connections.
Battery test: Use a multimeter to confirm the battery is fully charged (12.6 volts or higher).
If the battery is low, charge it using an appropriate battery charger or jump-start the vehicle.

3. Starter Relay Check

Locate the fuse box: Open the fuse box according to the owner's manual.
Identify the starter relay: Refer to the fuse diagram in the fuse box cover.
Swap the relay: Remove the starter relay and replace it with a similar relay from another function (e.g., horn).
Attempt to start the vehicle again.

4. Starter Motor Inspection

If the clicking persists, check the starter motor:
- Remove starter motor: Disconnect the battery (negative cable), then remove any covering or shields to access the starter.
- Inspect wiring and connections: Check for loose or damaged wires.
- Bench test starter motor: If accessible, connect the starter motor directly to a known good battery to see if it engages.

5. Final Steps

If all components are functioning but the vehicle still won't start, consider checking the ignition switch or neutral safety switch.
Reassemble all components, reconnect the battery, and ensure everything is secure.
