Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set to "Park" or "Neutral."
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery:
- Clean any corrosion from the terminals using a wire brush and a mixture of baking soda and water.
- Tighten battery terminals to ensure a good connection.
Replace Battery (if needed):
- Remove the old battery by unfastening the hold-down bracket.
- Carefully lift the battery out of the tray.
- Install the new battery in reverse order, ensuring correct polarity.

3. Starter Motor Replacement

Remove Starter Motor:
- Disconnect the positive battery terminal.
- Remove any covers or shields obstructing access to the starter.
- Unbolt the starter motor from its mounting bracket.
- Disconnect the wiring harness and positive cable from the starter.
Install New Starter Motor:
- Connect the wiring harness and positive cable to the new starter motor.
- Bolt the starter motor in place securely.
- Reattach any covers or shields removed during disassembly.

4. Verification

Reconnect the negative battery terminal.
Start the vehicle to confirm the clicking noise is eliminated.
Check that all electrical systems function correctly.
