Solution

1. Preparation

Gather tools: Multimeter, socket set, battery terminal cleaner, jumper cables, and a wrench.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Disconnect the negative terminal of the battery using a wrench.
Clean corrosion from battery terminals and cable connectors with a battery terminal cleaner.
Reconnect the terminals, ensuring they are tight.

3. Battery Replacement (if necessary)

If the battery voltage is low (below 12.4 volts), replace the battery:
- Disconnect both terminals (negative first, then positive).
- Remove the battery hold-down clamp and carefully lift out the old battery.
- Place the new battery in the tray, reconnect the positive terminal first, then the negative.

4. Starter Inspection and Replacement

If the battery is functioning properly but the clicking persists, test the starter:
- Locate the starter motor (usually near the transmission).
- Disconnect the electrical connectors from the starter.
- Remove the mounting bolts using a socket set and pull the starter out.
- Install the new starter by reversing the removal steps, ensuring all connections are secure.

5. Final Check

Reconnect the battery terminals securely and ensure all tools are removed from the engine compartment.
Attempt to start the vehicle to check if the issue is resolved.
