Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (or neutral) and the parking brake is engaged.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Check Battery Condition
- Inspect battery terminals for corrosion; clean them with a wire brush if necessary.
- If the battery voltage is below 12.4 volts, consider charging or replacing the battery.
Replace Battery
- If replacement is needed, remove the battery hold-down clamp with a socket set.
- Disconnect the positive terminal first, followed by the negative terminal.
- Install the new battery by connecting the positive terminal first, followed by the negative terminal.
- Secure the battery with the hold-down clamp.

3. Starter Motor Inspection

Visual Inspection
- Check the starter motor connections for any signs of damage or corrosion.
Test Starter Functionality
- If the battery is good, reconnect the negative terminal and attempt to start the vehicle.
- If the clicking persists, proceed to remove the starter motor.
Remove Starter Motor
- Disconnect the battery again for safety.
- Remove any components obstructing access to the starter motor (like the air intake duct).
- Unbolt the starter motor from its housing using a socket set and disconnect the wiring harness.
Test or Replace Starter Motor
- If the starter motor is accessible, test it with direct voltage from a battery.
- Replace the starter motor if it fails the test.
